# 2. Volume USDT Moving

We use the moving method of calculating the trading volume, which shows the value at the current moment, minus N periods ago, where "N" is the selected timeframe. 

The difference between moving and candlestick (bar) trading volume is that when a candle closes, the volume value is not reset to zero.
