What is the Weighted Moving Average (WMA) Indicator?
The Weighted Moving Average (WMA) is a moving average that puts more weight on recent price bars, so it reacts faster than a Simple Moving Average. It plots as a single line on your chart. Read it like any moving average: slope tells you direction, and price behavior around the line tells you whether the trend has control.
The WMA shows trend direction and dynamic support/resistance with less lag than equal-weight averages. Don't try to make it do more than that.
How is the Weighted Moving Average (WMA) Indicator Calculated?
The WMA multiplies each price in the lookback by a weight, sums those weighted prices, and divides by the total of the weights. Recent bars get heavy weights. Older bars get light ones.
The formula: WMA = sum(w_i × P_i) / sum(w_i)
On a 14-period WMA with linear weights, today's bar gets a weight of 14, yesterday's gets 13, down to 1 for the oldest bar. The total weight comes from n(n+1)/2.
Default lookback on most platforms is 14 periods. Shorter settings react faster but produce choppier signals. Longer settings smooth the line but confirm slower. Pick based on your timeframe.
How to Use the Weighted Moving Average (WMA) Indicator in Trading?
Use the WMA as a trend filter and timing line. Rising WMA with price above = bullish bias. Falling WMA with price below = bearish bias. That's your foundation.
Here are the testable ways traders use it:
Trend bias: Take longs only when price is above a rising WMA. Take shorts only when price is below a falling WMA. Trade with the slope, not against it.
Pullback entries: In an uptrend, buy a pullback that tags the WMA and then closes back above it. In a downtrend, sell a rally that rejects the WMA and closes back below. The line is your trigger, not your entry.
Price/WMA crossover: A close above the line signals momentum shifting up. A close below signals momentum shifting down. You get far fewer false signals when the WMA slope agrees with the cross direction.
Two-WMA cross: A fast WMA crossing above a slow WMA confirms trend acceleration. Crossing below confirms deceleration and bearish control. Stick to one short-period WMA and one longer-period WMA, not three or four stacked on top of each other.
Stops and invalidation: Place stops beyond the most recent swing low/high, or beyond the WMA zone after a pullback entry. A clean break and hold through the line means the trend is losing control. Exit before the position becomes a -3R trade.
