Candlesticks

GET
https://api.onetrading.com/fast/v1/candlesticks/{instrument_code}
public
Get instrument candlesticks for a specified time period. The requested time period may include up to 5000 candlesticks; for example, a request for minutely candles is limited to at most approximately 83 hours. Please note that fewer candlesticks than the theoretical limit may be provided for a given time period due to gaps in trading activity. Additionally, the endpoint now accepts a parameter called 'countBack,' which specifies the exact number of bars to load. If not provided, the default value is set to 5000. It's important to note that 'countBack' takes precedence over 'from' when both parameters are present.
