Double top / double bottom (DOUBLE-TAP)

How the setup is identified

Identifies a double top or double bottom — two failed attempts at the same level — and trades the reversal from the second attempt.

Status and evidence

Zero fires — entry conditions too strict for live gold. Fired 233 times in replay and never once live, which is its own warning about replay-only results.

What we learned

This one produced the most useful negative result in the set: it fired 233 times in replay and never once live. The gap is not a bug, it is a measurement of how much easier pattern identification is when the outcome is already known.

Any strategy showing a large replay-to-live frequency gap should be treated with suspicion regardless of its replay profitability. It is the same lesson as FAILED-BREAKOUT-FADE, arriving through a different route.
