Volume Weighted Moving Average (VWMA)

Volume Weighted Moving Average (VWMA) is a moving average in which each closing price is weighted by the trading volume of its candle. This means that high-activity periods have a greater influence on the indicator’s value than low-volume “quiet” candles.

Trend Identification with VWMA

VWMA is used like other moving averages — by comparing it to the current closing price:

• Price above the VWMA line → buy signal (long).
• Price below the VWMA line → sell signal (short).

🔵 Thanks to volume weighting, VWMA more accurately reflects real market consensus: price moves backed by high trading interest shift the line more, while low-volume moves have little effect on its position.

VWMA Price Crossover

When the current price crosses the VWMA line, it may signal a local trend change:

• Crossover from above downward → signal to open a short position.
• Crossover from below upward → signal to open a long position.

The key value of VWMA crossovers is signal quality: if the breakout is accompanied by high volume, the move simultaneously shifts the VWMA line and confirms the strength of the trend.

Calculation Formula

VWMA is calculated as the volume-weighted mean of closing prices over the last Length candles, where trading volumes serve as weights:

VWMA = Σ(Close[i] × Volume[i]) / Σ(Volume[i])

Where Close[i] is the closing price of candle i, Volume[i] is the trading volume of candle i, and the sum is taken over the last Length candles.

Note

Unlike EMA and SMMA, VWMA does not use a recursive formula — each value is recalculated fresh over the Length candle window. The only parameter is the period Length.

Timeframes and Practical Use

• On liquid pairs with high trading volume, VWMA produces the most reliable signals — volume data is trustworthy there.
• On illiquid pairs or non-standard timeframes, volume data quality may be poor, reducing the accuracy of the indicator.

👉 VWMA works best in combination with momentum indicators (RSI, MACD) or volatility indicators (ATR). Use it as a signal quality filter, not as a standalone entry trigger.

Use in Veles Bots (Flexible Indicators)

Available settings:

• Period — number of candles for calculation. Range: 2–500, default value: 20.
• Interval — candle timeframe.
• Method — calculation type. By bar close (on the selected interval only), or by minute (once per minute for any interval).
• Shift — shifts the requested indicator value back by the specified number of candles.

Limitations

• VWMA is a trend indicator: it shows the direction of movement based on participant activity, but does not predict reversals.
• The indicator depends on volume data quality: on pairs with manipulated or unrepresentative volume, signals may be unreliable.
• For better accuracy, it is recommended to use VWMA in combination with other indicators (RSI, ATR, EMA) and support/resistance levels.
• In Veles bots, VWMA can be used as an entry or exit filter, combined with any other conditions.

Summary

VWMA is a trend filter that accounts for real market activity when calculating the moving average. In Veles bots, it helps filter out entries on low-volume moves and build strategies based on market-participant-confirmed trends. Most effective on liquid pairs in combination with momentum indicators such as RSI or MACD.
