#chart

Historical price for any crypto token by its on-chain contract address, keyless. Unlike current-price APIs, this is the time dimension: a price chart over any window, the price at any past date or timestamp, the percentage change over a period, and the token first-ever recorded price. Works for any token on any chain by chain:address (and coingecko:id), covering long-tail tokens centralized APIs miss. Live, nothing stored. The token price-history layer for charting, backtesting, accounting, tax and analytics apps — distinct from current-price and coin-slug APIs, this prices a token HISTORY by contract address.

Live conversion of OHLC candles into the alternative chart types traders use to filter noise — computed on demand, no key, nothing cached. Convert candles to Heikin-Ashi (which smooths price action and clarifies trend); build Renko bricks from a price series and a brick size (stripping out time and small moves); and produce a Three Line Break chart (which only prints a new line on a confirmed move). Each carries the latest trend direction. Works for any market — forex, stocks, crypto or commodities. A chart-transformation engine, distinct from pattern-detection and indicator tools: it turns ordinary candles into the trend-clarifying chart types a discretionary trader reads.

Live historical price data and analytics for any crypto coin, from the public CoinGecko feed. Get open/high/low/close candles over a date range; the price, market cap and volume time series; the move over a period with its high and low; and a coin's multi-period performance with all-time-high and all-time-low. Works for thousands of coins in any quote currency. A crypto history-and-analytics layer — distinct from spot-price and whole-market feeds: it turns the price archive into the candles, time series and moves a trader studies. Live, with a short upstream cache.
