Candlestick Pattern Screener (Multi-Asset) API

healthy 3,874 Subscribers

Which markets just printed a reversal or continuation candlestick pattern on their latest daily candle, computed live from Yahoo Finance (no key, nothing stored). Candlestick patterns are the oldest price-action signals there are: a hammer at a low hints a bounce, a shooting star at a high a turn, an engulfing candle a momentum shift. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this reads each asset's most recent candles and detects the classic single- and two-candle patterns (doji, hammer, inverted hammer, shooting star, hanging man, bullish/bearish engulfing, bullish/bearish harami, marubozu), tagging each bullish, bearish or neutral. The screener endpoint returns every market flashing a pattern right now, split into bullish and bearish signals. The asset endpoint returns one market's latest candle with any pattern detected on it. The patterns endpoint lists what is recognised. The cross-asset candlestick-pattern screener cut — distinct from the crypto-only pattern detector and the bring-your-own-candle pattern API. It scans the whole market for price-action signals at once.

Crypto Candlestick Pattern Detector API

Which reversal and continuation candlestick patterns have just printed on a coin, and which coins across the market are flashing one right now, detected live from Binance candles — no key, nothing stored. Candlestick patterns are the oldest price-action signals there are: a hammer at the bottom of a move, a bearish engulfing at the top, a doji marking indecision. The detect endpoint fetches a pair's recent candles and returns the patterns found on the latest ones — each with its name, whether it is bullish, bearish or neutral, the candle it formed on and a short meaning — plus the latest OHLC. The screener endpoint scans a basket of coins and surfaces the ones whose most recent completed candle just formed a bullish or bearish reversal pattern, so you can find fresh setups across the market in one call. The symbols endpoint lists tradable pairs. This is the coin-native candlestick-pattern screener cut for crypto — it fetches the live data itself, distinct from the generic pattern-recognition calculator (which you feed your own OHLC), the Donchian breakout, the momentum and the volume-profile APIs in the catalogue. Detected patterns include hammer, shooting star, bullish/bearish engulfing, doji, marubozu and morning/evening star. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; interval is 1h/4h/1d/1w.

Candlestick Pattern API

Live candlestick-pattern recognition that traders and trading bots run on OHLC candles — computed on demand, no key, nothing cached. Detect the patterns that complete on the last candle of a series; scan a whole series for every pattern occurrence with its position; or list the 24 supported patterns. Each match carries a bullish, bearish or neutral signal. Works for any market — forex, stocks, crypto or commodities. A pattern-recognition engine, distinct from numeric-indicator and support-resistance tools: it turns raw candles into the reversal and continuation signals a chartist reads.

Stock Index Seasonality API

The calendar patterns equity traders position around — "Sell in May", the Santa Claus rally, the September swoon — computed live from ~10 years of Yahoo Finance monthly data across the world's major stock indices (no key, nothing stored). Equities have well-documented seasonal tendencies, and this measures them directly: for each index it takes a decade of monthly returns, groups them by calendar month, and returns the average return in each of the twelve months, the share of years that month was positive (the win rate), and the historically strongest and weakest months. The seasonality endpoint returns one index's full 12-month seasonal profile plus the current month's historical bias. The month endpoint flips it around: for a calendar month it ranks every index by its historical average return, so you can see which markets are seasonally strong or weak right now. The indices endpoint lists what is covered, from the S&P 500, Nasdaq, Dow and Russell to the DAX, FTSE, CAC, Euro Stoxx, Nikkei and Hang Seng. The equity-index seasonality / calendar-pattern cut — distinct from the FX, commodity and crypto seasonality APIs, the index price feed and the constituent APIs.

Commodity Seasonality API

The calendar patterns commodity traders position around, computed live from ~10 years of Yahoo Finance monthly futures data (no key, nothing stored). Commodities are the most seasonal market there is: natural gas tends to rally into winter heating demand, gasoline into the summer driving season, grains around the planting and harvest calendar. This measures it directly — for each commodity it takes a decade of monthly returns, groups them by calendar month, and returns the average return in each of the twelve months, the share of years that month was positive (the win rate), and the historically strongest and weakest months. The seasonality endpoint returns one commodity's full 12-month seasonal profile plus the current month's historical bias. The month endpoint flips it around: for a given calendar month it ranks every commodity by its historical average return, so you can see what is seasonally bullish or bearish right now. The commodities endpoint lists what is covered. The commodity-seasonality / calendar-pattern cut — distinct from the FX-seasonality API (currencies), the commodity-price feed, the commodity-spreads and the commodity-momentum APIs. It answers what a commodity usually does this month, not what it costs today.
