Closing Strength (CLV) API

Where each market closes inside its daily range, and what that says about who is in control into the bell, computed live from Yahoo Finance daily OHLC — no key, nothing stored. The close is the most important price of the day: a market that runs up but closes back near its low was sold into all afternoon (distribution), while one that closes on its highs has buyers in firm control (accumulation), even if the headline change is the same. The Close Location Value (CLV) captures this on a -1 to +1 scale — +1 is a close exactly on the high, -1 exactly on the low, 0 the middle of the range. This API turns it into a conviction gauge. For each instrument it returns today's CLV, the average CLV over the window (a positive average means closes persistently in the upper half — accumulation; negative means distribution), the recent 20-day CLV as the current pressure reading, the share of days that closed in the upper third versus the lower third of their range, and a plain-language read. The asset endpoint returns one instrument's full closing-strength profile; the screener endpoint ranks the cross-asset universe from strongest accumulation to heaviest distribution, so you can see where buyers are quietly winning the close. This is the close-location / accumulation-distribution-pressure cut, price-only and no volume — distinct from the candlestick-pattern API (named shapes on the last bar), the volume-indicator tools and the price feeds. It is who won the day.

Candlestick Pattern Screener (Multi-Asset) API
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"e=USDT form; interval is 1h/4h/1d/1w.

TradingView Technical Ratings API
Live technical-analysis ratings and market screeners from TradingView, with no key. TradingView's famous "Strong Buy / Buy / Neutral / Sell / Strong Sell" gauge aggregates around 26 indicators into one consensus rating; this reads TradingView's own public scanner and returns it cleanly across crypto, US stocks and forex. Get the full technical rating for any symbol — the overall consensus plus the separate moving-average and oscillator sub-ratings, with the live RSI, MACD, ADX and Stochastic values; screen a market for the top movers ranked by change, volume, rating or price, each with its rating; and find symbols by name with their price and rating. The technical-signal / screening layer for trading dashboards, screeners, alpha tools and analytics. Distinct from single-indicator APIs — this is TradingView's aggregated consensus rating and multi-symbol screener. Live from TradingView; short cache only.

Variance Ratio Test API
A formal statistical test of whether a market follows a random walk, or whether its returns carry tradeable momentum or mean-reversion that is real rather than noise — the Lo-MacKinlay variance ratio test, computed live from Yahoo Finance daily closes, no key, nothing stored. Most persistence tools give you a single descriptive number; this gives you a hypothesis test with a verdict. The variance ratio compares the variance of multi-day returns to the variance of one-day returns scaled up: under a true random walk the ratio is 1 at every horizon. A ratio above 1 means returns positively autocorrelate (trends persist — momentum); below 1 means they reverse (mean-reversion). Crucially it attaches a heteroskedasticity-robust z-statistic and a p-value at each horizon, so you know whether the deviation from a random walk is statistically significant or just sampling noise — the thing a point estimate cannot tell you. The asset endpoint runs the test at horizons of 2, 4, 8 and 16 days and returns each ratio, z-statistic, p-value and a reject/fail-to-reject verdict, plus an overall read. The screener endpoint ranks the cross-asset universe by their 2-day variance ratio, separating the statistically momentum-like markets from the mean-reverting ones. This is the random-walk hypothesis-test cut — distinct from the Hurst-exponent regime API (a point estimate with no significance), the momentum and the price APIs. It is the test, with the p-value attached.
