Histogram 

Understanding Histograms for Data Analysis

 

In data analysis, histograms serve as essential visualizing tools that allow one to comprehend numerical data distribution visually. By representing information graphicaly, they offer insight into patterns underlying any dataset's frequency or patterns of change. This article introduces histograms by exploring their components as well as their significance within data analysis.

A histogram is a visual representation of data organized into bins or intervals along the horizontal axis and showing frequency or count of points falling into each bin on its vertical axis, providing analysts with information regarding shape, central tendency and spread in any dataset.

Bins: Horizontal bars or intervals along the x-axis that divide data into discrete ranges;

Frequency: Vertical bars on the y-axis that indicate counts or frequencies within each bin;

And finally: the horizontal axis displays ranges of values or intervals over time.

Title and Labels (description of histogram and labels on x and y axes to assist interpretation).

Constructing a Histogram:

For creating a histogram, please follow these steps:

 

Establish the range of data points and choose an appropriate number of bins, by either dividing into equal intervals or selecting intervals with variable widths based on its characteristics. Finally, count how many data points fall under each bin.

 

Create the Histogram: A histogram provides valuable insights into data distribution and patterns; key interpretations include:

 

Shape: Histogram shapes may range from symmetric, left skewed (left or right skew) or uniform; these indicate how data has been distributed across time. Central Tendency: Through careful study of its peak or highest frequency bin, histograms can reveal data's central tendency, such as mean median mode (MMM).

 

Spread: Histograms allow one to observe the spread or dispersion of data by measuring bin width and frequency distribution. Histograms also can identify outliers - points which deviate significantly from the majority and appear as isolated bins in their graph - helping identify them quickly and allowing for their identification as outliers. Eventually Histogram Applications include V.

Applications of Histograms

Histograms find applications across numerous fields, such as:

 

Quality Control involves the identification and correction of variations and defects in manufacturing processes. Finance analyzes stock price movements and returns.

 

Healthcare examines patient demographics and medical test results before providing care, while Social Sciences investigate income distribution and survey responses.

 

Machine Learning: From data preprocessing and feature engineering

 

Histograms are powerful visual tools for comprehending numerical data's distribution and characteristics. By offering an accessible representation, histograms allow analysts to extract valuable insights and make sound decisions across many fields. Mastery in histogram construction equips data professionals with accessing hidden patterns within datasets to gain valuable knowledge that they might otherwise remain hidden from view.

4 Types of Forex (FX) Trend Indicators

Many forex traders spend their time looking for that perfect moment to enter the markets or a telltale sign that screams "buy" or "sell." And while the search can be fascinating, the result is always the same. The truth is, there is no one way to trade the forex markets. As a result, traders must learn that there are a variety of indicators that can help to determine the best time to buy or sell a forex cross rate.

Here are four different market indicators that most successful forex traders rely upon.

Indicator No A Trend-Following Tool

It is possible to make money using a countertrend approach to trading. However, for most traders, the easier approach is to recognize the direction of the major trend and attempt to profit by trading in the trend's direction. This is where trend-following tools come into play.

Many people try to use them as a separate trading system, and while this is possible, the real purpose of a trend-following tool is to suggest whether you should be looking to enter a long position or a short position. So let's consider one of the simplest trend-following methods—the moving average crossover.

A simple moving average represents the average closing price over a certain number of days. To elaborate, let's look at two simple examples—one long term, one shorter term.

The chart below displays the day/day moving average crossover for the euro/yen cross. The theory here is that the trend is favorable when the day moving average (in yellow) is above the day average (in blue) and unfavorable when the day is below the day. As the chart shows, this combination does a good job of identifying the major trend of the market—at least most of the time. However, no matter what moving-average combination you choose to use, there will be whipsaws.

The chart below shows a different combination—the day/day crossover. The advantage of this combination is that it will react more quickly to changes in price trends than the previous pair. The disadvantage is that it will also be more susceptible to whipsaws than the longer-term day/day crossover.

Many investors will proclaim a particular combination to be the best, but the reality is, there is no "best" moving average combination. In the end, forex traders will benefit most by deciding what combination (or combinations) fits best with their time frames. From there, the trend—as shown by these indicators—should be used to tell traders if they should trade long or trade short; it should not be relied on to time entries and exits.

Indicator No A Trend-Confirmation Tool

Now we have a trend-following tool to tell us whether the major trend of a given currency pair is up or down. But how reliable is that indicator? As mentioned earlier, trend-following tools are prone to being whipsawed. So it would be nice to have a way to gauge whether the current trend-following indicator is correct or not.

For this, we will employ a trend-confirmation tool. Much like a trend-following tool, a trend-confirmation tool may or may not be intended to generate specific buy and sell signals. Instead, we are looking to see if the trend-following tool and the trend-confirmation tool agree.

In essence, if both the trend-following tool and the trend-confirmation tool are bullish, then a trader can more confidently consider taking a long trade in the currency pair in question. Likewise, if both are bearish, then the trader can focus on finding an opportunity to sell short the pair in question.

One of the most popular—and useful—trend confirmation tools is known as the moving average convergence divergence (MACD). This indicator first measures the difference between two exponentially smoothed moving averages. This difference is then smoothed and compared to a moving average of its own.

When the current smoothed average is above its own moving average, then the histogram at the bottom of the chart below is positive and an uptrend is confirmed. On the flip side, when the current smoothed average is below its moving average, then the histogram at the bottom of the figure below is negative and a downtrend is confirmed.

In essence, when the trend-following moving average combination is bearish (short-term average below long-term average) and the MACD histogram is negative, then we have a confirmed downtrend. When both are positive, then we have a confirmed uptrend.

At the bottom of the chart below, we see another trend-confirmation tool that might be considered in addition to (or in place of) MACD. It is the rate of change indicator (ROC). As displayed in the chart below, the orange-colored line measures today's closing price divided by the closing price 28 trading days ago.

Readings above indicate that the price is higher today than it was 28 days ago and vice versa. The blue line represents a day moving average of the daily ROC readings. Here, if the red line is above the blue line, then the ROC is confirming an uptrend. If the red line is below the blue line, then we have a confirmed downtrend.

Note below that the sharp price declines experienced by the euro/yen cross from mid-January to mid-February, late April through May and during the second half of August were each accompanied by:

  • The day moving average below the day moving average
  • A negative MACD histogram

Indicator No. 3: An Overbought/Oversold Tool

After opting to follow the direction of the major trend stage, a trader must decide whether they are more comfortable jumping in as soon as a clear trend is established or after a pullback occurs. In other words, if the trend is determined to be bullish, the choice becomes whether to buy into strength or buy into weakness.

If you decide to get in as quickly as possible, you can consider entering a trade as soon as an uptrend or downtrend is confirmed. On the other hand, you could wait for a pullback within the larger overall primary trend in the hope that this offers a lower risk opportunity. For this, a trader will rely on an overbought/oversold indicator.

There are many indicators that can fit this bill. However, one that is useful from a trading standpoint is the three-day relative strength index, or three-day RSI for short. This indicator calculates the cumulative sum of up days and down days over the window period and calculates a value that can range from zero to If all of the price action is to the upside, the indicator will approach ; if all of the price action is to the downside, then the indicator will approach zero. A reading of 50 is considered neutral.

The chart below displays the three-day RSI for the euro/yen cross. Generally speaking, a trader looking to enter on pullbacks would consider going long if the day moving average is above the day and the three-day RSI drops below a certain trigger level, such as 20, which would indicate an oversold position.

Conversely, the trader might consider entering a short position if the day is below the day and the three-day RSI rises above a certain level, such as 80, which would indicate an overbought position. Different traders may prefer using different trigger levels.

Indicator No A Profit-Taking Tool

The last type of indicator that a forex trader needs is something to help determine when to take a profit on a winning trade. Here, too, there are many choices available. In fact, the three-day RSI can also fit into this category. In other words, a trader holding a long position might consider taking some profits if the three-day RSI rises to a high level of 80 or more.

Conversely, a trader holding a short position might consider taking some profit if the three-day RSI declines to a low level, such as 20 or less.

Another useful profit-taking tool is a popular indicator known as Bollinger Bands. This tool takes the standard deviation of price-data changes over a period, and then adds and subtracts it from the average closing price over that same time frame, to create trading "bands." While many traders attempt to use Bollinger Bands to time the entry of trades, they may be even more useful as a profit-taking tool.

The chart below displays the euro/yen cross with day Bollinger Bands overlaying the daily price data. A trader holding a long position might consider taking some profits if the price reaches the upper band, and a trader holding a short position might consider taking some profits if the price reaches the lower band.

A final profit-taking tool would be a "trailing stop." Trailing stops are typically used as a method to give a trade the potential to let profits run, while also attempting to avoid losing any accumulated profit. There are many ways to arrive at a trailing stop. The chart below illustrates just one of these ways.

The trade shown below assumes that a short trade was entered in the forex market for the euro/yen on January 1, Each day the average true range over the past three trading days is multiplied by five and used to calculate a trailing stop price that can only move sideways or lower (for a short trade), or sideways or higher (for a long trade).

The Bottom Line

If you are hesitant to get into the forex market and are waiting for an obvious entry point, you may find yourself sitting on the sidelines for a long while. By learning a variety of forex indicators, you can determine suitable strategies for choosing profitable times to back a given currency pair. As you gain confidence, you'll be able to determine pairs of indicators that will help pinpoint trade opportunities.

Also, continued monitoring of these indicators will give strong signals that can point you toward a buy or sell signal. As with any investment, strong analysis will minimize potential risks.

MACD Histogram & Crossover: Everything You Need to Know

MACD Histogram

Momentum trading can be a nerve-wracking experience. If done right, you can rack up a lot of profit quickly. If not, you can falter and make wrong buy/sell decisions that can send you down a spiral of losses. One tool to help traders in momentum is the use of the MACD indicator and the MACD histogram. Here, we will discuss how you can make the most out of it.

What is the MACD Histogram Momentum Indicator?

The Moving Average Convergence Divergence (MACD) is an indicator that tracks trend momentum. It shows the connection between two moving averages of a market’s price. You get the MACD by subtracting the period EMA from the period EMA (Exponential Moving Average). With this, you have the MACD line.

The MACD indicator alone does not provide enough information when it comes to buy or sell signals. For this, you will need the signal line. The signal line is basically a 9-day EMA of the MACD. With this line plotted over the MACD line, you can easily see when to buy or sell.

For instance, if the MACD line is above the signal line, then your bias is to go short. Conversely, you go long when the MACD is below the signal line. There are many ways to look at the MACD indicator. However, most traders use it to identify divergences, crossovers, as well as rapid rises or falls. We will discuss MACD indicator strategies later.

MACD Histogram Calculation Formula

The MACD line is generated based on a calculation which subtracts the period EMA (also called long-term EMA) from the period EMA (short term EMA). From this, we can have the MACD histogram by subtracting the signal line from the indicator line.

The EMA is a type of moving average that prioritizes more recent data points. EMA is sometimes called the exponentially weighted moving average. The difference between EMA and SMA (simple moving average) is that EMA gives more weight and significance to recent price changes. SMA merely applies an equal weight to everything in the period.

MACD Histogram Color

When you enable the MACD indicator, an indicator below the price chart.  (Read about other indicators here: ATR Indicator, Stochastic Indicator, RSI Indicator) The MACD line is the blue line and the signal line is the orange line. Usually, when you enable the MACD indicator, it also provides you with the MACD histogram. Here, you are given bar charts that move with the two lines, which is the histogram.

MACD Histogram Settings

While some traders have unique MACD histogram settings, you are better off sticking to the default settings. This is because the market is an ever-changing platform. Even though you found a setting that works today does not mean it will be effective tomorrow. So the best way to make the most out of the MACD histogram isn’t to optimize the settings, but rather to look at the signals produced from the default settings and learn how to go from there.

MACD Histogram Values

The value of the MACD histogram can be positive or negative. It is positive when the short-term EMA is above the long-term EMA. Conversely, it is negative if the short-term EMA is below the long-term EMA. The distance between the MACD to its baseline, whether above or below, indicates that the distance between the two EMAs is increasing.

MACD Histogram strategy

With the theories out of the way, let’s talk about how you can use the MACD histogram to identify entry and exit points. Keep in mind that engaging in momentum trading like this requires a nerve of steel. This is one reason why momentum trading is difficult because you need to wait for the right moment before taking action, and many people fail to do so and end up selling themselves short. The strategies below should help you get started.

Entry Strategy

Dr. Alexander Elder created the impulse system, which is used to identify entry points by using a momentum indicator to measure market inertia and another indicator to measure the momentum. In this case, we will use the exponential moving average (EMA) to measure the inertia and the MACD for momentum, both of which are included in the same MACD indicator.

When the EMA rises, the inertia has a bullish bias. When the EMA falls, the inertia has a bearish bias. For the MACD histogram, if it rises, then the bullish momentum is picking up steam. If it falls, then it is a bearish momentum. Below is the MACD indicator with the MACD line and signal line invisible and the EMA indicator enabled.

MACD Histogram Strategy

For this system, you are looking for the moment when the EMA and MACD histogram are pointing in the same direction. That would be your entry signal. This is because the inertia and momentum are pushing the trend upward or downward together. So, when both EMA and MACD histogram are on the rise, that means it is a bearish momentum and the trend is most likely to continue to go up. Conversely, if both EMA and MACD are going down, that means the trend is going down. (Also read about: Trendline Trading)

MACD Histogram Entry Strategy

There is a way to refine your entry points. If you are comfortable with trading with the daily charts, for example, then you should take a look at the weekly chart. You should analyze the bearish or bullish tendency of the market. To help you identify the market’s trend on a larger time scale, use the week EMA and weekly MACD histogram for the weekly chart.

When you know the long-term trend, you can go back to the daily chart and trade with the trend. In other words, you trade with the bigger picture in mind, thus minimizing risk. (Also read: Risk Reward Ratio) Favorable trades here are those that move in the same direction as the long-term weekly trend. In this case, you can use the day and MACD setting of and you can wait for the right signal.

Below is an example of the weekly chart and daily chart (respectively) both showing an upward trend, which indicates favorable trades.

MACD Histogram Entry Strategy 4

We will use the daily chart for our trading and the weekly chart to observe the long-term trend. You can trade in a different timeframe as well. To determine which is a viable long-term chart, simply multiply your current timeframe by 5 to 7. For instance, if you trade on the minute chart, the bigger timeframe is 1 hour and you should look at the 1-hour chart to identify the larger trend at play.

For instance, if you trade on the daily chart and use the weekly chart for reference, you wait until the day EMA and the MACD histogram to go up together. That is a strong buy signal and you should go long and stay there until the signal disappears, which is when the EMA and Histogram no longer go up together.

On the other hand, if the weekly trend is going down, wait until the day EMA and MACD histogram to go down on the daily chart. That is a good sell signal and you should go short then. Moreover, you should be ready to cover the short position the moment the buy signal disappears.

Techniques for Exiting Positions

Momentum trading can be very effective in both markets with a strong trend or choppy ones because it is done in a short timeframe. The best markets in any week are those that have strong intraday trends, and that is where you should be trading. This is why momentum trading requires a nerve of steel as intraday trading can be nerve-wracking. That said, remember to hop off the momentum train before it goes down and take your profit with it.

We’ve already covered the entry strategy. Your exit point is the moment when any of the indicators stops going up. On a daily trading chart, the MACD histogram tends to make that divergence first as the momentum of the trend weakens. Of course, the momentum slowing down means that the buy signal is gone. To some traders, that is not a true signal. However, using the impulse system, that is a sell signal.

If the weekly trend is going down and the EMA and MACD histogram are also going down on the daily chart, and that you are in a short position (and you should), it is best to cover your shorts the moment any of the two indicators stop giving a sell signal. That is when the downward momentum is losing steam and has already done most of its descent. You should sell before the trend hits rock bottom.

Unlike entry points, exit points require you to be quick on your feet take action the moment you see the trend is reaching its end. The whole system is all about riding the momentum so when it loses steam, you get out.

MACD Histogram TradingView

MACD Histogram is available on TradingView as well as a whole host of other forex online platforms. For TradingView, you need to create an account with them first before you can use their advanced features.

MACD Histogram Alert

Forex trading may not provide the most exhilarating experience most of the time. You can get bored or distracted and could potentially miss an entry or exit point if you don’t keep your eyes on the moving chart. For this reason, the community has created various MACD histogram alerts to ping you when a certain condition is met such as when the MACD line crosses the signal line. Many of them are highly customizable, some of which can send you an email to let you know of any notable update.

MACD Pros and Cons

The MACD is able to show the strength of the current market trend via the histogram. On top of that it is also able to identify overbought and oversold areas, whereby, the signal line value is more than the MACD value and where the signal value is less than the MACD value respectively. In addition, the MACD is highly customizable to your trading style. Furthermore, the MACD has multiple strategies alone, making it an advanced tool to master with multiple additions to your trading arsenal. However, it is a lagging indicator, meaning that the MACD crosses might have a few candles of delay, hence not providing the sharpest entry and exit possible. Subsequently, it is capable of providing conflicting signals during choppy markets, making it somewhat unreliable.

MACD Pros and Cons

MACD Crossover strategy

The MACD can give many signals within a certain period, thus it can be a challenge for traders to validate the strength of the signal. The degree in strength of the MACD crosses varies based on historical data. A MACD cross is taken to be stronger, with a higher probability, when the cross is well above the zero line, more than the previous recent cross that stands out.  The figure below illustrates this in a live chart..

MACD analysis

The MACD crossover strategy is one of the simplest and widely used strategy out there. To dissect the profitability of this strategy, a series of backtest is conducted in the H4 timeframe.

In this series of backtests, the pair EURUSD is taken as a sample representing the forex vehicle, AAPL is taken as a sample to represent the stocks vehicle and BTCUSD is taken as a sample to represent the cryptocurrency vehicle.

For simplicity, we will assume that all trades taken have a risk of 1% of the account.

Definitions:  Avg Risk reward ratio= ( Total risk reward ratio of winning trades/ total no. of wins)                Profitability (% gain)= (no. of wins* reward)- (no of losses* 1) [ Risk is 1%]

The examples of the backtest are as shown in the following figures:

MACD analysis 1

MACD analysis 2

MACD analysis 3

For the Backtest results, trades with blue and yellow zones indicate an overall win with the blue zone as reward and the yellow zone as the risk taken.

As shown in our backtest, the win rate of this strategy for EURUSD (Forex) is 30%, AAPL (Stocks) is 40% and BTC (Crypto) is 20%

The average risk reward ratio of this strategy for EURUSD (Forex) is , AAPL (Stocks) is and BTC (Crypto) is  

The profitability of this strategy for EURUSD (Forex) is , AAPL (Stocks) is and BTC (Crypto) is

MACD Conclusion

Although the MACD crossover strategy doesn’t have a fantastic win rate or an outstanding average risk to reward ratio, hence making it seem somewhat unprofitable, it is only one of the many strategies to utilise the MACD indicator. There are no doubt other more advanced and profitable strategies out there to utilise it. Even so, the MACD is a very useful and widely used tool for indication, alongside other indicators to be added into your setup. Not to mention that it can be customised to fit trading styles as well.

And that is everything you need to know about MACD histogram to get started. If you are not familiar with momentum trading, it is best to start with a demo account with some virtual currency to start so you can get some experience before you put your actual capital at risk.
