What is the A/D Line API?
The Accumulation/Distribution Line is a cumulative volume-flow indicator. Each bar's contribution is weighted by where the close falls within the high-low range — a close near the high adds more than a close near the low. When the A/D Line rises alongside price, volume confirms the trend. When A/D diverges from price (one goes up, the other down), it signals potential reversal. Our API delivers the current A/D value so your bot can detect divergence without aggregating tick data yourself.

Frequently Asked Questions
How is the A/D Line calculated?
Each bar's Money Flow Multiplier = ((Close - Low) - (High - Close)) / (High - Low). This is multiplied by volume to get the Money Flow Volume. The A/D Line is a running cumulative sum of these values. Brokers use tick volume, which is the basis for our calculation.
Why does the A/D value look like a large number?
A/D is a cumulative indicator — it accumulates volume-weighted values from the start of the data series. The absolute number is not meaningful by itself; what matters is the direction and trend of the A/D line relative to price. Compare current values to historical values using the history endpoint.
How do I detect A/D divergence programmatically?
Fetch A/D history alongside OHLC history for the same symbol and timeframe. Compare the slope of the last N A/D values against the slope of the last N closing prices. If price trend and A/D trend move in opposite directions, that is divergence.
Is A/D different from OBV?
Yes. On-Balance Volume (OBV) adds full volume when close is up and subtracts it when close is down. A/D uses a multiplier based on the close's position within the high-low range, giving partial credit based on where price closed — making it more nuanced than OBV for Forex candles.
