When 61.8% fails on purpose

Many traders treat 61.8% as a magnet that must bounce. In the Practice Lab we treat it as a decision point: hold with structure intact, or fail and force a stand-aside.

What “fail” looks like

Price tags 61.8%, prints a close beyond it in the counter-trend direction, and the prior swing low (or high) that defined the impulse also gives way. The Fib did its job — it framed the test. The trade idea did not survive.

What we rehearse

• Speak the invalidation level before the candle closes
• Avoid “averaging” into a broken Fib as if the ratio owed you a bounce
• Switch to the higher timeframe to see whether your impulse was nested inside a larger opposing move

Carry-out rule

If 61.8% fails with a structure break, the next action is flat, not heroic. Bring a failed example to the next group evening; the room learns faster from broken charts than from perfect ones.
