Crypto Volume Profile (VPVR) API

healthy 4,500 Subscribers

Where a crypto pair has actually traded the most volume by price level, computed live from Binance candles — no key, nothing stored. Most charts show volume over time; the volume profile shows it over price, and that is where support and resistance really live. The profile endpoint splits the price range into buckets and distributes each candle's volume across the prices it spanned, returning the volume-by-price histogram, the Point of Control (POC — the single price with the most traded volume, the market's fair-value magnet), the Value Area (the price band holding roughly 70% of all volume) with its high (VAH) and low (VAL), and the high-volume nodes. The levels endpoint returns just those key levels plus where the current price sits relative to the value area — above it (acceptance higher), inside it, or below — the read traders use for mean-reversion and breakout setups. The symbols endpoint lists tradable pairs. This is the volume-by-price / market-profile cut for crypto — distinct from the raw OHLCV candle feed, the time-of-day seasonality API, the trade-size distribution and the order-flow APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; interval is 15m/1h/4h/1d.

FX Pivot Points API

Live FX pivot points — the classic support and resistance map traders watch — as an API, computed from European Central Bank daily reference rates. For any currency pair it takes the prior completed week's or month's high, low and close and returns the central pivot P plus three resistances (R1, R2, R3) and three supports (S1, S2, S3), in both the Classic and Fibonacci methods. It also returns the current rate, whether it sits above the pivot (bullish bias) or below (bearish), and the nearest level above and below — ready-made entry, target and stop levels. Get a pair's pivots, or scan a whole basket for bias at a glance. A support/resistance layer for forex, trading and charting apps. Live, no key. Distinct from rate, strength, volatility, correlation, signal (MA/RSI), range, seasonality and drawdown APIs — this is the pivot-point S/R map.

Crypto Pairs Trading & Spread API

The statistical-arbitrage signal between two coins — how stretched their price ratio is versus its own recent average, computed live from Binance daily candles (no key, nothing stored). Pairs traders do not bet on direction; they bet on the spread between two correlated coins reverting to its mean. When ETH/BTC (or any ratio) runs two standard deviations above its average, the spread is stretched — short the rich leg, long the cheap one, and profit when it snaps back. The spread endpoint takes two coins and returns the current price ratio, its rolling mean and standard deviation, the z-score (how many standard deviations stretched), the return correlation of the two coins (pairs trading works on correlated pairs) and a long/short mean-reversion signal. The screener endpoint scans every pair in a liquid basket and ranks them by absolute z-score — the most stretched, most tradeable spreads right now. The coins endpoint lists what is covered. The pairs-trading / relative-value spread cut for crypto — distinct from the correlation-&-beta API (which gives the correlation matrix, not the tradeable spread), the single-coin momentum, the funding-arbitrage and the price APIs. It answers whether a spread is stretched, not whether two coins move together.

Altcoin Season Index API

One number that tells you whether crypto capital is rotating into altcoins or huddling in Bitcoin, computed live from Binance daily candles (no key, nothing stored). The market swings between two regimes: in "altcoin season" most alts outperform Bitcoin and money chases the long tail; in "Bitcoin season" alts bleed against BTC and capital flees to the majors. The classic gauge is simple — of the top altcoins, what share has outperformed Bitcoin over the last 90 days? Above ~75% it is altcoin season; below ~25% it is Bitcoin season. The index endpoint returns that index (0-100), the season label, Bitcoin's own return over the window and how many alts out- versus under-performed. The leaderboard endpoint ranks the alts by their excess return versus Bitcoin — who is leading the rotation and who is lagging — each with its own return, BTC's return and the gap. The coins endpoint lists the universe. The altcoin-season / alt-vs-BTC rotation cut — distinct from the market-cap-dominance and global-market APIs (which report BTC's share of total cap, not relative performance), the single-coin momentum and the price APIs. It answers whether it is altseason, not what the market cap is.

Crypto Smart-Money vs Retail Positioning API

How crypto's biggest, most-capitalised futures traders are positioned versus the retail crowd — and the divergence between them — computed live from Binance's public futures positioning feed (no key, nothing stored). Binance splits its perpetual traders into the whole crowd and the "top traders" (the top ~20% of accounts by margin balance, a smart-money proxy) and publishes the long/short split of each. When smart money leans one way while the crowd leans the other, that gap is a classic contrarian signal: an over-long retail crowd the big accounts are quietly fading often marks a local top, and vice versa. The positioning endpoint returns, for a coin, the long/short ratio and long-share of three cohorts side by side — the global crowd, the top traders by account, and the top traders by position size. The divergence endpoint returns the smart-money-minus-retail gap with a plain-language read. The history endpoint returns the time-series across 5m to 1d buckets so you can watch the gap open and close. The smart-money-versus-retail / positioning-divergence cut for crypto — distinct from the single-cohort long/short-ratio feed, the funding-rate, open-interest and price APIs. It tells you who is on which side, not just how many are long.
