Exit when price enters an opposing supply/demand zone?

Your trade is running, and ahead of it sits a thick supply (or demand) zone you've marked — a wall that should stop the move cold. The question isn't whether the zone is real. It's whether a zone you drew should override a system that didn't.

Supply and demand zones mark areas of presumed unfilled orders. They sometimes cause sharp reactions — and they're sometimes sliced straight through as if they weren't there. Worse, their boundaries are subjective: tighten or widen the zone and the “reaction” story changes. That subjectivity alone should disqualify it as a hard exit trigger.

Supply and demand zones are frequently consumed rather than respected, and where exactly you draw them is subjective. A self-drawn wall isn't a system-defined exit.

Obvious zones are often weak ones

The cleaner and more obvious a zone looks to you, the more obvious it is to everyone, which frequently means it gets absorbed rather than defended. Reacting to every opposing zone means exiting in front of the many that fail to hold — sacrificing the continuation your strategy was built to capture.

Tested rules over drawn boxes

If reaching an opposing zone reliably ended trades, it would live in the exit logic. It doesn't, because across a real sample it doesn't pay. This is the same family as the order block and trendline questions: discretionary chart objects don't get veto power over a tested trade. Let the stop and target run.

A supply or demand zone is a box you drew around a hope. Tested winners pass through those boxes constantly — don't exit in front of one.
