Understanding the Force Index and Its Impact on Momentum Trading

The Force Index is a trend-following indicator that integrates price and volume data. It helps traders identify trade signals within trends as well as detect divergences.

Force Indices tend to signal upward trends. Conversely, when they reach new highs they often signify the continuation of an uptrend; conversely if they drop lower lows this may signal that downtrends could be weakening and are becoming vulnerable for reversal higher.

Trend Confirmation

Alexander Elder created The Force Index as an indicator to assess price moves based on three essential elements – direction, extent and volume. It serves as an oscillator – moving in either positive or negative territory depending on shifts in balance of power. It can help strengthen an overall trend or detect corrective moves within playable correction zones or foreshadow potential reversals with divergences.

The Force Index differs from most indicators by taking both price and volume into consideration. This makes it easier for traders to open positions aimed at major market participants; plus it makes calculations much simpler! Plus it’s convenient.

Calculating the Force Index involves subtracting the previous close from the current one and multiplying that figure by volume; then averaging that result over an appropriate time period – usually 13 bars. If the force index value goes past certain thresholds, this signals buy or sell signals; otherwise it should remain constant.

However, traders should keep in mind that the Force Index is a lagging indicator and should only be traded alongside other technical tools. Doing so could lead to overconfidence and poor risk management practices.

Thus, using the index in combination with moving averages and price can help filter out unnecessary signals while focusing on those most likely to produce profitable trades.

As part of trading the Force Index, the initial step should be identifying key support and resistance levels on your chart and closely watching them for potential trading opportunities. Once an opportunity has been identified, use of this indicator can confirm it as well as help define entry points.

To identify the ideal trading opportunities, it’s essential to look out for when the force index rises above a threshold level and when price EMA positively slopes. Conversely, for short trades look out when force index falls below threshold levels or price EM negatively slopes – these could be ideal signals for buying trades!


Force Index indicators provide an effective means of measuring the strength of buyers and sellers; they can also be used to detect divergences. When prices move in one direction while an indicator moves another way, this may signal that there will soon be an upcoming reversal; creating trading opportunities that offer considerable potential profits.

The force index is a lagging indicator, meaning it uses historical price and volume data to calculate an exponential moving average (EMA), which means it may take time before providing trade signals. A longer period can help smooth out oscillations and minimize false signals generated by this indicator.

An increased force index reading indicates that buyers are stronger than sellers and that there is strong commitment underlying price movements, making this an excellent indicator for traders looking to buy or short sell stocks within specific trends.

Conversely, a low force index reading indicates that sellers are stronger than buyers and there is weak commitment underlying price movement – an alarm bell for traders looking to sell or purchase stocks in any particular trend.

During uptrends, the force index often spikes upon strong price breakouts with high volume, serving to validate and confirm its legitimacy and increase chances of success in trading. Meanwhile, sideways movements and pullbacks typically cause the force index to mean-revert towards zero as size of price moves and volumes tend to diminish over time.

As such, traders must rely on the force index in conjunction with other indicators to ensure that any trade meets all necessary criteria. Ideally, trades should be opened when the force index rises above zero and closed when it falls back below it; in this way, traders can avoid opening too many positions that are likely to fail and reduce false trades; additionally, this approach helps traders avoid selling into strong downtrends.

Trend Reversal

Alexander Elder first introduced The Force Index indicator in his book “Trading for a Living”. It oscillates above and below zero to provide information on price movements based on direction, magnitude and volume. It can also be used for trend confirmation by highlighting potential price reversals through divergences.

Price movements reveal the relative strength of buyers and sellers in the market. Their magnitude reveals market changes’ duration while volume provides insight into commitment behind each move. A combined indicator is then calculated to give a sense of bull or bear dominance: when it reaches new highs it indicates more bull power and an upward trend could continue; conversely when falling below previous lows means bear strength is increased and therefore downward trends could persist.

When both the force index and price EMA reach new highs simultaneously, this signals an uptrend; conversely if either drops and decreases simultaneously then this indicates selling activity. Divergences between price EMA and force index can also provide trading signals, however they must be supported by other indicators for confirmation purposes.

In general, traders will look to buy when the 13-day exponential moving average (EMA) of force index is above its centerline and sell when it falls beneath. Traders can adjust the number of periods used to create more or less smooth movements in an indicator; longer-term traders typically employing more periods than shorter-term traders. The Force Index can be utilized to confirm trending prices, identify playable corrections and foretell reversals via divergences. Add Force Index as a study easily by clicking the Add Studies button in the Edit Chart menu and choosing Force Index from the available studies list. You can even modify its period settings for reduced trading signals produced by this indicator.


Alexander Elder created the Force Index as an indicator to measure price movements’ momentum. It incorporates three important aspects of momentum trading: direction, extent and volume. As such it can be used to reinforce trends, predict corrections or identify divergences.

Direction: When measuring an upward or downward trend, higher readings represent buyers as being stronger than sellers while lower readings indicate sellers as being the lead force. Extent: Any significant price move shows high commitment from either side and strong buying or selling pressure; hence a high Force Index reading indicates its reach and extent of trending activity.

Formula for Calculating Force Index. A Force Index can be easily calculated using this simple formula: the difference between recent closing price and previous one multiplied by current trading volume. Since it is a lagging indicator, it may take time for trade signals to come through; using a moving average to approximate it may speed up this process.

As such, the Force Index can be combined with other indicators to enhance its accuracy of signals it generates. When trading uptrends or downtrends occur, buy when the 2-day exponential moving average moves positively while sell when moving negative.

Force Index can also be used to detect corrections and divergences in price movements, for instance when higher lows appear despite continued price appreciation; or when lower highs appear when prices decline – an indication of potential sustained downtrends or corrections respectively.

As with other technical indicators, the Force Index may produce false signals. To increase accuracy of its signals it is advisable to combine it with other indicators like Money Flow Index and Relative Strength Index to enhance its accuracy. Furthermore, traders must remember that Force Index is a lagging indicator; thus it takes some time for data to reach it so it is wise to monitor it frequently for changes.
