By Marco BösingWhat Are Session High & Low?
Session high and low refer to the highest and lowest prices reached within a defined trading session (e.g., the regular US session, the Asia session, or the London session). These extreme points are far more than statistics — they mark zones where significant concentrations of stop orders and liquidity accumulate.
Institutional participants frequently use session extremes as reference points for entries and exits. When a session high or low is broken, it can either signal a genuine breakout or trigger a stop run, where liquidity above or below the extremes is swept before the market reverses.
Understanding session highs and lows is a fundamental building block for analyzing market structure and liquidity flows.
