Volume Indicators API
Live volume-based technical indicators that traders run to confirm a move with the volume behind it, computed on demand from the OHLCV candles you pass in — no key, no cache, nothing stored. The mfi endpoint returns the Money Flow Index, a volume-weighted version of RSI that swings from 0 to 100, with an overbought reading above 80 and oversold below 20. The obv endpoint returns On-Balance Volume, the running total that adds a candle's volume on an up close and subtracts it on a down close, together with whether it is rising or falling — rising OBV confirms buying pressure. The cmf endpoint returns the Chaikin Money Flow, which sums money-flow volume over the lookback to show whether buyers or sellers are in control. These indicators all need the volume of each candle, which makes them a fundamentally different tool from price-only indicators like RSI, MACD, Stochastic and ADX: they answer whether volume is confirming the price move or diverging from it. Works for any market — forex, stocks, crypto or commodities — because you supply the candles with volume. Computed locally and deterministically, so it is instant and private. Ideal for trading bots, divergence screeners, breakout confirmation and trading dashboards. Candles are open:high:low:close:volume. Live, nothing stored. 3 compute endpoints. For price-only indicators use a technical-indicators, oscillators or trend-indicators API.
