Get Trap Detection Signal

Trap detector — failed-breakout fade opportunities at gamma walls.

Flags failed breakouts (bull trap / bear trap) as fade opportunities when dealer long gamma reinforces a reversal at a resistance/support wall. Standalone detector, not part of the MSI composite.

Logic highlights (src/signals/advanced/trap_detection.py):

• breakout_buffer_pct = min(0.1%, 0.15 × realized_sigma × √5) — vol-scaled noise floor.
• Upside-fail (bear fade): close > resistance + buffer AND net_gex > 0 AND gamma strengthening AND call wall NOT migrating up.
• Downside-fail (bull fade): mirror, with put wall NOT migrating down.
• Score = 0.4 + 0.4 × distance_strength + 0.2 × gex_boost, then flow multiplier.
• Triggered when |score| ≥ 25 (clamped 0.25).

Params: symbol (default SPY). Returns 404 when no data exists.

• score — [-100, +100].
• signal — "bullish_fade" | "bearish_fade" | "none".
• triggered — true when |score| ≥ 25.
• breakout_up / breakout_down — whether price has crossed the buffer.
• call_wall / prior_call_wall — current and ~30min-ago resistance level.
• put_wall / prior_put_wall — current and ~30min-ago support level.
• call_wall_migrated_up — invalidates a bear fade when true.
• put_wall_migrated_down — invalidates a bull fade when true.

Trader interpretation:

• signal == "bearish_fade" + breakout_up == true → price poked above the broken_resistance_level (now sitting below close) but dealers are long gamma and the call wall hasn't migrated; short-call-spread / put-debit.
• signal == "bullish_fade" → mirror play; price slipped beneath broken_support_level (now sitting above close), put wall hasn't migrated, and is set up for a reclaim.
• call_wall_migrated_up == true (bear fade) or put_wall_migrated_down == true (bull fade) → setup invalidated; dealers repositioning with price.

Note on field naming. broken_resistance_level and broken_support_level refer to the level price has just breached — so on an upside breakout the "broken resistance" sits below close, and on a downside breakdown the "broken support" sits above close. This is intentional: the trap setup keys off the recently-breached level, not the next unbroken one above/below.
