#vortex

Live trend-following indicators that traders run to ride a trend and time its turn, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The supertrend endpoint returns the SuperTrend line, the ATR-banded trailing level that sits below price in an uptrend (acting as support) and above it in a downtrend (acting as resistance) and flips when a close crosses it, with the current trend. The aroon endpoint returns Aroon Up, Aroon Down and the Aroon Oscillator, which measure how recently the highest high and lowest low were made — a reading of 100 means it just happened — to tell you how fresh and strong the trend is. The vortex endpoint returns the Vortex Indicator's VI+ and VI- lines, whose crossover is a classic trend-change signal. These are trend-following indicators, deliberately distinct from the ADX, Parabolic SAR and Donchian set and from momentum, volatility and volume tools: they each use the high, low and close to follow a trend and flag its reversal with their own formula. Works for any market — forex, stocks, crypto or commodities — because you supply the candles. Computed locally and deterministically, so it is instant and private. Ideal for trend-following bots, signal dashboards and back-tests. SuperTrend defaults to period 10 multiplier 3; Aroon to 25; Vortex to 14. Live, nothing stored. 3 compute endpoints. For ADX/Parabolic-SAR/Donchian use a trend-indicators API; for RSI/MACD use a technical-indicators API.
