Session highs & lows as liquidity
Liquidity & Stop Hunts
Every session leaves its own pool
The Asian session prints its own high and low. So does London. So does New York. Each one becomes a fresh, short-term liquidity pool that the NEXT session frequently targets before setting its own direction.
The overnight range is a built-in map
You don't need to guess where liquidity sits at the open. The overnight session already drew it for you. Its high and low are usually the first two levels the new session tests.
The first move isn't always the real move
The initial push at a session open frequently exists just to grab the prior session's liquidity. Treat it as information, not confirmation, until you see what happens after the grab.
