Candlestick

A candlestick is a chart representation of price movement over a single interval, showing the open, high, low, and close values for that period.

Each candle condenses an interval into four prices, the open and close forming the body and the high and low forming the wicks, so a glance conveys direction and range. A sequence of candles is the standard way to visualize price history. A candlestick is the graphical form of one OHLCV record, so our OHLCV feed directly supplies the data a chart renders, at any interval a caller requests, as a cheap read for portfolio and trading views.
