VWMA: Volume-Weighted Moving Average

הרעיון במילים פשוטות

A price reached on heavy trading says more than one reached on a quiet candle. The VWMA lets the busy candles pull the average harder, so it hugs the prices where most of the business was done.

איך זה מחושב

Multiply every close of the last N candles by its volume, add them up and divide by the total volume of those candles. On CFDs and forex the volume is the tick count: how many price changes there were.

VWMA = Σ(close × volume) ÷ Σ(volume) over the last N candles

איך משתמשים בזה

• Read it like any moving average: rising means an uptrend, the price above it means buyers are in control.
• Compare it with an SMA of the same period: VWMA above the SMA means the rises came on more volume than the falls.

הסקת מסקנות

• When VWMA and SMA are nearly equal, volume was spread evenly.
• A big gap between them points to one-sided, heavy trading.

ממה להיזהר

• Tick volume is a stand-in for real volume; it works well for comparisons within one ticker, less across tickers.

קצת היסטוריה

Volume-weighted averages grew out of the institutional VWAP benchmark; the moving version became a standard indicator in charting software in the 1990s.
