Low of Day

Low of day (LOD) is the lowest price printed in the current regular session, and the intraday support level the most eyes are on. Longs place stops just beneath it; short sellers watch it as the trigger for a fresh leg down.

That stop clustering is what gives LOD breaks their character: when the level goes, resting sell stops execute at once, producing a sharp flush. Sometimes the flush is the start of a trend day lower; sometimes it is a washout that clears the weak hands and marks the exact bottom. Volume and the speed of the reclaim decide which — a LOD break that snaps back above the old low within minutes is a classic reversal signal.
