#donchian

Which markets are breaking out of their recent trading range, computed live from Yahoo Finance (no key, nothing stored). The Donchian channel — the highest high and lowest low of the last N days — is the breakout system the legendary Turtle traders rode: a close above the 20-day high is a classic long entry, below the 20-day low a short, and the 55-day channel is the slower, higher-conviction version. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 20-day and 55-day Donchian channels (upper, lower and midline), where price sits inside the 20-day channel, and flags fresh breakouts above the high or below the low. The screener endpoint returns the upside and downside breakouts across the board plus the channel-position ranking. The asset endpoint returns one market's Donchian card. The universe endpoint lists what is covered. The cross-asset Donchian / channel-breakout (Turtle) screener cut — distinct from the crypto-only Donchian screener, the 52-week-range screener (a much longer window), the Bollinger-Bands screener and the bring-your-own-candle indicator APIs. It catches the range breakouts across every asset class at once.

Which coins are breaking out of their recent trading range, computed live from Binance candles — no key, nothing stored. The Donchian channel is the highest high and lowest low of the last N periods; a price above the upper band is a classic trend-following breakout (the original turtle-trading signal) and a price below the lower band a breakdown. The breakout endpoint returns, for one pair, the N-day Donchian upper and lower bands, the current price, where it sits in the channel (0% at the low, 100% at the high), the distance to each band and a status — new_high, new_low, near_high, near_low or inside. The screener endpoint scans a basket of coins and surfaces the ones currently breaking to new highs (momentum-long candidates) and to new lows (breakdowns), ranked by how decisively they have cleared the band. The symbols endpoint lists tradable pairs. This is the range-breakout / Donchian-screener cut for crypto — distinct from the generic indicator calculators (which you feed your own data), the volume-profile, the seasonality and the order-flow APIs in the catalogue. Bands use the prior completed candles, so a breakout is a genuine move beyond the established range. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; lookback is 5-200 days.

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.
