Trend Indicators API

Live trend and direction indicators that traders run to gauge whether a market is trending and which way, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The adx endpoint returns the ADX (Average Directional Index) with the +DI and -DI lines using Wilder's method, so you get both the strength of a trend (a reading above 25 signals a real trend) and its direction. The psar endpoint returns the Parabolic SAR — the trailing stop-and-reverse level that sits below price in an uptrend and above it in a downtrend, and flips when price crosses it — together with the current trend. The donchian endpoint returns the Donchian Channel: the highest high and lowest low over the lookback with the midline, and whether the last close has broken out of the channel. These indicators all need the full high, low and close, and they answer a different question than momentum oscillators, closes-only indicators or volatility tools: is there a trend, and which way is it going. Works for any market — forex, stocks, crypto or commodities. Computed locally and deterministically, so it is instant and private. Ideal for trend-following bots, breakout screeners, trailing-stop logic and trading dashboards. ADX needs 2 x period + 1 candles. Live, nothing stored. 3 compute endpoints. For RSI/MACD use a technical-indicators API; for Stochastic/CCI use an oscillators API.
