Crypto Trade Size Distribution API

healthy 4,922 Subscribers

Who is actually trading a pair — retail or whales — read from the composition of Binance's aggregated trade tape by trade size, no key, nothing stored. Order flow tells you the net direction; this tells you the size profile behind it: whether a move is driven by a swarm of small retail prints or a handful of large institutional ones, often the more important signal. The distribution endpoint scans the recent aggregated trades for a pair and buckets them into size cohorts (micro under $1k, retail $1k-$10k, mid $10k-$100k, whale over $100k), returning each cohort's trade count, volume in base and quote and its share of total volume, plus the whale-volume share — the single read on how institutional the flow is. The percentiles endpoint returns the trade-size percentiles (p50, p90, p99) and the average, median and largest trade. The symbols endpoint lists tradable pairs. This is the trade-size composition / participant-mix analytics cut for crypto — distinct from the order-flow / CVD API (which measures buy-versus-sell direction), the order-book depth, the slippage and the price APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form.

Crypto Order Flow & CVD API

Who is actually hitting the market — buyers or sellers — read live from Binance's aggregated trade tape, no key, nothing stored. Every trade carries a flag for which side was the aggressor: a taker buy lifts the ask, a taker sell hits the bid. Summing those over a window gives order flow — the net buying or selling pressure that price action follows — and its running total is the Cumulative Volume Delta (CVD), the metric order-flow traders watch to spot absorption and divergence. The flow endpoint scans the recent aggregated trades for a pair (up to 5,000) and returns the taker-buy and taker-sell volume in base and quote, the delta (buy minus sell), the CVD over the window, the buy/sell ratio, the share of volume that was buying, a net-pressure label and the time span covered. The large endpoint surfaces the big prints — single aggressive trades above a notional threshold — and tags each as a taker buy or sell, so you see the whale orders moving the tape, with the buy- and sell-side large-trade totals. The symbols endpoint lists tradable pairs. This is the trade-flow / CVD microstructure analytics cut for crypto — distinct from the raw recent-trades feed, the order-book depth and the price, ticker and slippage APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form.

Crypto Options Put/Call Ratio & Sentiment API

The single headline gauge of how the crypto options market is positioned, computed live from Deribit's public option book — no key, nothing stored. The put/call ratio is the amount of put activity divided by call activity: a low ratio means the market is loaded with calls (bullish, greedy positioning), a high ratio means puts dominate (hedging, fear). The ratio endpoint returns, for a currency (BTC or ETH), the market-wide put/call ratio computed two ways — by open interest (the standing positioning) and by 24-hour volume (today's flow) — with the call and put totals, the spot index and a plain-language sentiment label. The expiries endpoint breaks the put/call ratio down by expiry, revealing the term structure of sentiment: whether hedging is concentrated in the near term or further out. This is the aggregate options put/call sentiment cut for crypto — distinct from the US-equity put/call API (a different market), the max-pain / open-interest positioning view, the implied-vol skew surface and the gamma-exposure APIs in the catalogue. Below roughly 0.7 is call-heavy and bullish, above 1.0 put-heavy and defensive; it is most useful read as a contrarian gauge. Currency is BTC or ETH, the two assets Deribit lists liquid options for.

Crypto RSI & Oscillator Screener API

Which coins are overbought or oversold right now, computed live from Binance candles — no key, nothing stored. Momentum oscillators are the classic mean-reversion signals: a Relative Strength Index (RSI) above 70 says a coin is overbought and stretched, below 30 oversold and washed out, while the Stochastic oscillator times the turn within the recent range. The oscillators endpoint fetches a pair's candles and returns its Wilder RSI(14), the Stochastic %K and %D, and a plain signal (overbought, oversold or neutral) on a chosen timeframe. The screener endpoint scans a basket of coins and surfaces the ones that are currently overbought (possible pullback) and oversold (possible bounce), ranked by how stretched they are. The symbols endpoint lists tradable pairs. This is the coin-native oscillator / mean-reversion screener cut for crypto — it fetches the live data itself, distinct from the generic oscillator calculators (which you feed your own OHLC), the momentum trend-alignment, the Donchian breakout and the candlestick-pattern APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; interval is 1h/4h/1d/1w.

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.
