The UI told a swing-trade story (entry -> target -> stop) while the engine runs
a momentum portfolio (buy strength, trail out, re-rank). The selection was
honest; everything around it was borrowed from a strategy we don't run.
The target is never an exit under `atr_trailing`: `_atr_trailing_close()` does
not even take it as a parameter. It exists only to compute the R:R and touch
odds that admit a setup through the activation gate. Backtested exit reasons for
the production strategy: 144 initial stop, 98 trailing stop, 78 max hold —
target 0. See docs/research/sr-levels-and-exits.md.
What changed:
- New ExitPlanPanel on every setup card states the rules that actually close the
trade: initial stop (1R), the price at which the 3x ATR trail takes over from
it, the trail width in R, and the max hold. Derived in lib/exitPlan.ts from the
live exit policy, so it follows Admin rather than hardcoding the default.
- New BaseRatesPanel replaces per-target "probability" as the answer to "what
usually happens": win rate, average hold, best/worst R, and how trades actually
ended — measured under the real exit, from the backtest report.
- "Target"/"target probability" relabelled to "level"/"touch odds" and grouped as
gate metrics, with the R:R. On the dashboard focus card, residual momentum
(the actual signal) takes the headline stat those two used to occupy.
- The take-trade dialog no longer offers a target dropdown whose value the exit
ignores; it states the trailing plan instead. The picker returns only when the
live policy is mode='target', where the choice is real. The stored target is
now the setup's own, not whichever row was last clicked while exploring.
- "Played out" is gone. A setup was declared dead once price reached the target —
backwards under a trailing exit, where reaching a level is the good case and
the trade keeps running. Only the stop invalidates a setup now; running past
the entry is an "extended" warning, measured in R (you'd be chasing).
The levels ladder, the price rail and the chart overlay all stay fully
explorable — clicking a level still drives them. It is framed as overhead
structure, which is what it is, rather than a menu of exits.
Adds a parity guard: the UI recovers ATR as |entry - stop| / 1.5, so the test
fails if the scanner's stop width ever moves.
