Stock Split & Adjustment

Backtests must declare whether candles are adjusted; otherwise return curves lie.

Adjustment types

Forward adjustment aligns history to today's price; backward keeps historical levels. Vendors name them differently.

Ex-dividend gaps

Corporate action days create price gaps — strategies should tag them, not treat as volatility.

Align with API

Confirm TIQEX kline field docs and pick one adjustment convention in your backtest engine.

Backtest traps

Mixing adjusted and unadjusted series breaks indicators; lock one convention and data_version during sweeps.
