Accumulation/Distribution (A/D)

الفكرة بكلمات بسيطة

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).

طريقة الحساب

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

كيفية الاستخدام

• 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.

استخلاص النتائج

• The level of the line means nothing; only its direction and its divergences matter.

ما يجب الانتباه إليه

• 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.
