The flip is the level at which estimated dealer positioning changes sign — damping above, amplifying below, or the reverse depending on the market. It is one of the most watched numbers in dealer-flow analysis and one of the most consistently misused.
What it actually marks
A change in behaviour, not a price objective. Above it, hedging flow absorbs moves; below it, hedging flow extends them. Crossing it means the character of the session changes, and that is the information.
Nothing in the mechanism pulls price toward the level. The flip is where the regime switches, in the same way a coastline is where the terrain changes rather than somewhere the water is trying to go.
The mistake in practice
Traders set targets at the flip and hold losing positions waiting for price to reach it. Price has no obligation to. It can spend an entire session well away from the flip, and often does.
The trade the level supports is different: adjust expectations when price crosses. Tighten stops on a move into the amplifying side. Expect ranges to hold on the damping side. Neither of those requires price to visit any particular number.
It moves
The flip is computed from a book that changes continuously. It is not a fixed level for the session; it drifts as positioning shifts and can move substantially around an expiry or after a large trade.
A flip level noted at the open and referenced at three in the afternoon may describe a market that no longer exists. This is why the path matters as much as the value — a flip walking steadily higher all day is a market being repositioned, and that is worth more than the number itself.
The practical use
Treat it as a switch for how you trade, not a level you trade toward.
