Crypto Donchian Breakout Screener API

healthy 4,367 Subscribers

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.

Bollinger Bands & Squeeze Screener API

Which markets are coiled for a breakout and which are stretched to their bands, computed live from Yahoo Finance (no key, nothing stored). Bollinger Bands wrap a 20-day average in plus/minus two standard deviations; price riding the upper band is strong, the lower band weak, and — the prized signal — when the bands pinch tight (a "squeeze"), volatility has compressed and a big move usually follows. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's bands, its %B (where price sits between the lower band at 0 and the upper at 100), the bandwidth and whether bandwidth is at a multi-month low (a squeeze, breakout pending). The screener endpoint returns the board with the markets in a squeeze, the ones breaking above the upper band and the ones breaking below the lower. The asset endpoint returns one market's Bollinger card. The universe endpoint lists what is covered. The Bollinger Bands / volatility-squeeze screener cut — distinct from the bring-your-own-candle technical-indicator APIs, the FX-only z-score API and the market-breadth API. It finds the coiled springs across the whole market.

52-Week High/Low Range Screener API

Where every major asset sits in its one-year range — across stocks, indices, bonds, commodities, FX and crypto — computed live from Yahoo Finance (no key, nothing stored). The 52-week high/low is the single most-watched level in markets: assets breaking to new 52-week highs are in confirmed uptrends and chased by momentum, while new 52-week lows mark capitulation, and the "new highs / new lows" list is a classic breadth and momentum read. This places each instrument in its range as a 0-100 position (0 = sitting on its 52-week low, 100 = at its 52-week high), with how far it is below the high and above the low, and flags fresh new highs and new lows. The screener endpoint returns the whole multi-asset universe ranked by range position — what is breaking out at the top and breaking down at the bottom — plus the new-high and new-low lists. The asset endpoint drills into one instrument. The universe endpoint lists what is covered. The 52-week-range / new-highs-new-lows momentum cut across asset classes — distinct from the crypto Donchian-breakout screener (crypto only) and the single-quote, index, commodity and stock price feeds, which carry the 52-week high/low as a field but do not rank it across a multi-asset book.

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.

Golden Cross / Death Cross Screener API

Which markets just flipped trend on the most-watched signal in technical analysis — the 50-day vs 200-day moving-average cross — computed live from Yahoo Finance (no key, nothing stored). A golden cross, the 50-day average crossing up through the 200-day, is the classic confirmation of a new uptrend, and a death cross the opposite; funds and headlines move on them. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 50- and 200-day moving averages, whether it is in a golden-cross (bullish) or death-cross (bearish) regime, how many days since the last cross, and how far price sits above or below each average. The screener endpoint returns the whole board with the markets that have crossed most recently — the fresh golden and death crosses — and the bullish/bearish tally. The asset endpoint returns one market's moving-average card. The universe endpoint lists what is covered. The moving-average-crossover / golden-cross screener cut — distinct from the bring-your-own-candle technical-indicator APIs, the market-breadth API (which aggregates the share above a single moving average) and the FX-only signals API.
