Force Index

What is Force Index?

The Force Index is a metric that uses  volume and price  to determine the force behind a move in price or to define future tipping points. It was used in his seminal novel, Trade for a Living, created by Alexander Elder. There are three basic elements to price movement of a product, according to Elder: speed, scale, and quantity.

The Force Index incorporates all three like an oscillator, fluctuating as the balance of force changes across both favorable and negative areas. It may be used to reinforce the overall pattern, to classify functional corrections or to foreshadow divergent reversals. It  can also be referred to a mathematical metric, calculating the  strength used to push an asset’s level. The force index utilizes price and volume to assess the power behind a change in the market.

The three main components of the force index are market change speed, price change scale and amount of trade. The resulting formula will reliably calculate major shifts in the strength of bulls and bears when used in combination with  moving average. In this way, elder took a very effective single predictor, moving average, and combined it with his intensity index to gain much greater predictive performance.

What does Force Index Indicator Tells You?

A force index relates the present price to a prior price and then multiplies it over the period by distance. The corresponding meaning can be positive or negative. The force factor is usually calculated over many times. The force indicator then says whether the price has made further movement upward or downward, and therefore how much amount or pressure is behind the change. 

Rather large demand changes and very high volume are correlated with high force index readings. Broad demand fluctuations that lack volume can result in an index of force that is not as large or small (compared to where the volume is big). As the index of force tends to gage consumer power or energy, it may be used to help validate patterns and breakouts.

How does Force Index Operate?

The force index is determined by subtracting the closure of yesterday from the closing of today, then multiplying the sum by the today’s amount. When today’s trading rates are higher compared to yesterday, the power is good. The power is unfavorable if the closing rates are weaker than yesterday’s ones. The level of force is measured  by a greater market shift and a larger volume.

How to Calculate Force Index?

To measure a 1-period force index, the following formula is used:

Force Index (x) = [near (current period) close (prior period)] x volume

It is calculated as an exponential moving scale. Under other terms, previous data points from the calculation above are used and the metric is determined as an sum of these subsequent values. Most recent data points hold greater weight than older data points, with an linear running average.

Accordingly, the metric is measured in the general form: 

Force Index (n) = n – period  moving average of Force Index (x) 

Alexander Elder proposed a moving average of 13-periods and this is typically the default configuration for charting. Nonetheless, the specification of the periodicity can be changed depending on user feedback. Like the elder ray table, the data collected for the measure is taken on a regular basis, rendering its usage non-viable on narrower charting time frames (e.g. 4-hour, 15 minute, etc. ). It should operate on timescales that are greater than the regular (e.g. , weekly, monthly).

Force Index: Trend Identification

You may use  Force Index to reinforce or assess the phenomenon. Such a phenomenon, whether short-, medium- or long-term, depends on the parameters of  force index. Although the default parameter of  force index is 13, respectively, chartists may use higher or lower numbers for more or less smoothing. Note how the 13-day force index is more fluid and jagged when the 100-day force index becomes smoother and traverses the zero line fewer often. The 100-day force index may be used to assess the medium- to long-term pattern in this regard. Note how a price chart resistance breakdown leads to a break-out of pressure on the 100-day Force Scale. 

Calculating Bulls and Bears Moving Forces of Force Index

Force index calculates the force behind a pass. In other terms, the path of the transfer, the amount the price has risen and the quantity of the change at the moment. When a bar’s closing price is greater than the previous bar’s closing price, we might assume the impetus behind the change was either favorable or bullish. If the selling price is smaller than the corresponding bar closing price, then the impact has become pessimistic or bearish.

Unless the demand increase is only low, so the power behind the shift is only high. When there’s a major price shift then the impact is high. Therefore, the bigger the price shift, the greater the impact. And the greater the distance, the greater the power behind the transfer. The measure believes that differences are strictly related.

How do you do Technical Analysis for Force Index?

Trend and technology traders use a combination of patterns, indicators, and price tables to help them make financial decisions. Technical analysis is the process of determining the direction of the market based on the various stock charts used. Investors are analyzing the price chart to gain a better understanding of where markets are likely to move.

Force Index is an oscillator that measures the difference between the oscillations of two different oscillator types in the same system. When a force index is used in conjunction with a moving average (MA), the resulting numbers can measure significant changes in the power of bulls and bears.The force indices take into account factors such as market capitalization, market share and the number of shares in circulation.

According to many experts in technical analysis, It is one of the best tools to combine volume and price.The Force Index is often used as a technical analysis tool and is a moving candlestick chart of a stock, such as the Dow Jones Industrial Average (DIA).

For example, the extent of price movement, which brings the largest price advantage, shows the strongest buying pressure. According to Elder, there is a strong correlation between the price-to-volume ratio and the number of shares in circulation.

This indicator was created by Dr. Alexander Elder and uses price changes and trading volumes to measure the strength of bulls and bears. The logic is that the indicator tries to measure the force of the trend by combining stock movement and volume.

The oscillator focuses on the movement of the price-to-volume ratio of a stock over a period of time, rather than on the actual price.

How do you do fundamental Analysis for Force Index?

As you can see, the short-term strength index is smoothed with a moving average to help you find entry points into the market. Most traders buy when the Force index’s exponential moving averages are negative, and vice versa they sell when those averages become positive. As a trader, you should always act on the basis that the trend is represented by the moving average, not the long-term force index.

The Forex Index is a fast and simple tracker that uses the details on volume and price to help you make trading decisions. A short-term smooth Force Map, which we previously mentioned, helps define suitable entry points. A medium-term steady Force Index shows us the pattern and shifts in bullish and bearish powers in the markets at work. 

The Force Index should be used as an indicator in conjunction with other indicators and analytical techniques used by traders. The medium-term Smoothing Force Index tells us a lot more about the market and its prospects. 

When a force index is used in conjunction with a moving average (MA), the resulting numbers can measure significant changes in the power of bulls and bears. It is wise to use RSI and MACD together, as they measure market dynamics, but they can give opposite indications when measured against different factors. In this way, Dr. Elder takes the moving averages and combines them with his power indices for even greater predictable success. The Force Index is an indicator that uses the price volume to assess the force of a movement and identify potential turning points. 


Elder’s initial trading guidelines revolved around merging the Forex Index with two separate moving averages. The unique mix was a 2-day EMA used as a spatial short-term indicator, and a 13-period EMA used as a general pattern chart. 

Elder claimed that as force index’s intermediate-length moving average rises to a new level, bullish powers on the sector are rising. Which implies an uptrend is expected to persist. Similarly, as the Forex Index’s thirteen day EMA falls to new depths, it is gradually reflecting bearish powers in the economy.

It indicates that a downtrend will continue. When demand shifts are not accompanied by value, force Index intermediate-length EMA can flatten out. It can also arise if the huge quantities have only minor shifts in costs. In this way, a flattening out of Force Index indicates a turnaround may be closer. 

The measure of forces oscillates over and below zero. Price is known to be in an uptrend, if beyond zero. Price is called in downtrend if below zero. When price and index diverge, therefore that could be an indicator that the direction may shift. A longer duration on the tracker would deliver a smoother course with less oscillations. A shorter duration can result in a more fluid course and more rapid changes. Although that could be more suitable for people with limited timeframes, a larger percentage of false alarms would be vulnerable to this.  Thus, a prolonged duration would produce less signals whereas more signals would be produced in a shorter time span.

The force index is an oscillator that measures the relative strength of forces in a market, such as the force of an engine, truck or train.

This indicator reflects the market trend and can be used to reinforce the general trend or to identify a playable correction. This indicator shows the divergence of the situation and is used as an indicator reflecting market trends. The Force Index identifies playable corrections and deviations and can use the indicator to either reinforce general trends or identify playable corrections.

When used in conjunction with a moving average, the resulting numbers can measure significant changes in the power of bulls and bears. In this way, Elder takes the moving averages and combines them with its power indices for even greater predictable success. The Force Index comprises three key components, all of which measure the relative strength of forces in a market.

The indicator is based on price direction and trading volume, which, according to Elder, are the three main elements of price movement. The FI can confirm trends, see if there is a correction that is worthwhile, and even predict a reversal. This is the direction, scope and volume that are the main determinants of price developments in the market over a period of time.

The Force Index identifies playable corrections and deviations and can use the indicator to either reinforce general trends or identify playable corrections.
