Indicator values are computed server-side on every new candle. Your app queries the result — no TA library, no candle history needed.
A/D Line API — Smart-Money Volume Flow
The Accumulation/Distribution line shows whether volume is supporting or undermining price moves. Spot divergence early via a single REST call.

Why TickAtlas
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.

What developers ask first.
Straight answers on limits, coverage and how the endpoint behaves in production.
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. Our data uses 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.
