SuperTrend & Trend-Following API

healthy 3,337 Subscribers

Live trend-following indicators that traders run to ride a trend and time its turn, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The supertrend endpoint returns the SuperTrend line, the ATR-banded trailing level that sits below price in an uptrend (acting as support) and above it in a downtrend (acting as resistance) and flips when a close crosses it, with the current trend. The aroon endpoint returns Aroon Up, Aroon Down and the Aroon Oscillator, which measure how recently the highest high and lowest low were made — a reading of 100 means it just happened — to tell you how fresh and strong the trend is. The vortex endpoint returns the Vortex Indicator's VI+ and VI- lines, whose crossover is a classic trend-change signal. These are trend-following indicators, deliberately distinct from the ADX, Parabolic SAR and Donchian set and from momentum, volatility and volume tools: they each use the high, low and close to follow a trend and flag its reversal with their own formula. Works for any market — forex, stocks, crypto or commodities — because you supply the candles. Computed locally and deterministically, so it is instant and private. Ideal for trend-following bots, signal dashboards and back-tests. SuperTrend defaults to period 10 multiplier 3; Aroon to 25; Vortex to 14. Live, nothing stored. 3 compute endpoints. For ADX/Parabolic-SAR/Donchian use a trend-indicators API; for RSI/MACD use a technical-indicators API.

Crypto Donchian Breakout Screener API — oanor API marketplace

Crypto Donchian Breakout Screener API

Which coins are breaking out of their recent trading range, computed live from Binance candles — no key, nothing stored. The Donchian channel is the highest high and lowest low of the last N periods; a price above the upper band is a classic trend-following breakout (the original turtle-trading signal) and a price below the lower band a breakdown. The breakout endpoint returns, for one pair, the N-day Donchian upper and lower bands, the current price, where it sits in the channel (0% at the low, 100% at the high), the distance to each band and a status — new_high, new_low, near_high, near_low or inside. The screener endpoint scans a basket of coins and surfaces the ones currently breaking to new highs (momentum-long candidates) and to new lows (breakdowns), ranked by how decisively they have cleared the band. The symbols endpoint lists tradable pairs. This is the range-breakout / Donchian-screener cut for crypto — distinct from the generic indicator calculators (which you feed your own data), the volume-profile, the seasonality and the order-flow APIs in the catalogue. Bands use the prior completed candles, so a breakout is a genuine move beyond the established range. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; lookback is 5-200 days.

 Statistics Canada Economic Data API — oanor API marketplace

Statistics Canada Economic Data API

Key Canadian economic indicators from the official Statistics Canada Web Data Service. Pull the Consumer Price Index, the seasonally-adjusted unemployment rate, monthly real GDP, the Bank of Canada policy rate and the national population estimate — look up a single indicator, read a full country snapshot with all of them at once, or fetch the raw time series for any Statistics Canada vector by its id (with as many recent periods as you need). Every value carries the indicator label, its unit and the exact reference period, and always resolves to the latest published observation, so there are no dates to hard-code. Built for dashboards, macro research and CAD currency or rates models that need authoritative Canadian data. Distinct from market and FX feeds, and from our OECD cross-country indicators: this surfaces official Statistics Canada figures.

Every value carries the indicator label, its unit and the exact period it refers to, and always resolves to the latest published observation — no date juggling. Coverage spans Australia to the United States, with the United Kingdom, Germany, Japan, France and every other OECD member in between. Built for dashboards, macro research and currency or rates models that need authoritative, comparable cross-country economic data. Distinct from market and FX feeds: this surfaces official OECD statistics.

 Stock Market Fear & Greed Index API — oanor API marketplace

Stock Market Fear & Greed Index API

Live CNN Fear & Greed Index for the US stock market — no key, nothing stored. The equity-market sentiment gauge: a single 0–100 score (0 = extreme fear, 100 = extreme greed) built from seven market indicators, distinct from the crypto Fear & Greed index in the catalogue. The index endpoint returns the headline score and rating plus the previous close and the readings one week, one month and one year ago, so you can see how sentiment has shifted. The components endpoint breaks the index into its seven underlying indicators — market momentum, stock-price strength, stock-price breadth, put/call options, market volatility (VIX), junk-bond demand and safe-haven demand — each with its own score and fear/greed rating, so you can see what is actually driving sentiment. The history endpoint returns the daily score timeline for the last year. Build market-sentiment dashboards, contrarian-signal bots, risk dashboards and newsletter widgets on top of the most-watched sentiment gauge in equities. Score bands: 0–24 extreme fear, 25–44 fear, 45–55 neutral, 56–75 greed, 76–100 extreme greed.
