OHLCV meaning
Open, High, Low, Close, Volume. Interval is set by parameters such as 1m, 1h or 1d.
Time zones
Align calendars and time zones across markets to avoid lookahead bias in backtests.
TIQEX kline endpoints
Each market has a dedicated kline route with symbol, interval and limit — unified JSON arrays in responses.
Adjustments
Pin adjustment and calendar rules before cross-vendor compares; empty bars are often holidays, not halts.
Endpoints
See equity kline docs; backtest organization in /guides/backtesting-data-setup.
