Volume indicators
Accumulation/Distribution (A/D)
A running total of volume that leans towards buying when candles close near their highs and towards selling when they close near their lows.
用通俗的话解释
Where the price closes within its range tells you who won the candle. A/D adds a portion of the volume for closes near the high and subtracts it for closes near the low, building a line that shows whether money is flowing in (accumulation) or out (distribution).
计算方法
Each candle's position of the close in its range (from −1 at the low to +1 at the high) is multiplied by its volume and added to the running total.
Close location = ((close − low) − (high − close)) ÷ (high − low)
A/D = previous A/D + close location × volume如何使用
- Rising A/D confirms an uptrend; falling A/D confirms a downtrend.
- Divergence: price rising while A/D falls suggests the rally lacks real buying.
得出结论
- The level of the line means nothing; only its direction and its divergences matter.
示例
A stock trades flat for two weeks but closes near the top of each day's range: A/D climbs steadily, hinting at quiet buying before a breakout.

注意事项
- On currencies, metals and CFDs there is no central exchange volume. The chart uses "tick volume", the number of price changes in each candle, which follows real activity closely but is not the number of contracts traded.
