Crypto Smart-Money vs Retail Positioning API

healthy 4,873 Subscribers

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.

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-to-Macro Correlation API

Whether crypto is trading as a risk asset or a hedge, measured by how closely a coin moves with the stock market, gold and the dollar — computed live from Binance and Yahoo Finance, no key, nothing stored. The single most-asked macro question about crypto is whether it is "digital gold" or just high-beta tech; this answers it with numbers. The correlation endpoint returns, for a coin (BTC or ETH), its return correlation to the S&P 500, the Nasdaq 100, gold and the US dollar index over a chosen window, each with a plain-language read (risk-on if it tracks stocks, a hedge if it tracks gold or moves against the dollar) and an overall verdict. The beta endpoint returns the coin's beta to the S&P 500 — how much it amplifies equity moves — with the correlation and R-squared. This is the cross-asset / crypto-versus-traditional-markets correlation cut — distinct from the crypto-to-crypto correlation API (coins against each other), the realised-volatility and the price APIs in the catalogue. Correlations use daily log returns aligned on common trading days; coin is BTC or ETH, window 20-365 days.

Crypto Funding Rate Arbitrage API

The perpetual-futures funding rate for a coin side by side across the major exchanges, and the spread between them — computed live from each venue's public API, no key, nothing stored. A perpetual swap charges or pays funding every few hours to keep its price tethered to spot; when the same coin's funding differs across exchanges, a trader can be long the perp where funding is most negative (and gets paid) and short where it is most positive, harvesting the spread market-neutral. The funding endpoint returns, for a coin, the current funding rate on Binance, Bybit, OKX and Gate.io — per interval and annualised — the venue paying the most, the one charging the most, and the cross-exchange spread (the arbitrage edge). The screener endpoint scans a basket and ranks the coins by the size of that spread, surfacing the biggest funding-arbitrage opportunities. This is the cross-exchange funding-rate / basis-arbitrage cut for crypto — distinct from the single-exchange funding-rates feed (one venue), the spot-versus-perpetual basis and the price APIs in the catalogue. Funding is per interval (most venues settle every 8 hours); annualisation assumes three settlements a day, and intervals can differ by venue, so verify before trading. Coins are bases (BTC, ETH).
