Lineage

Declared at intake, carrying any prior negative result
Relation to prior work
experimental descendant
Note
Shares A03's broad causal shape (compression regime -> transition to decisive displacement -> continuation), measured via bar-to-bar range-overlap fraction instead of a short/long ATR ratio. Classified as a descendant rather than independent given genuine uncertainty about candidate-population overlap with A03, not because the calculation is identical.

Frozen specification

Snapshotted at intake — not re-read from a live module
Mechanism hypothesis
A transition from heavy short-horizon bar overlap/chop into low-overlap directional expansion predicts continuation.
Long rule
On a closed 5-minute bar i: if the average adjacent-bar range-overlap fraction over the 10 closed 5-minute bars strictly before i is >= 0.5 (a high-overlap compression regime), AND bar i's own overlap with bar i-1 is <= 0.15 (a sharp drop in overlap), AND bar i's own range >= 1.5x ATR(14) computed over the 14 closed 5-minute bars strictly before i, AND bar i closes above its open (bullish): enter LONG (continuation) at the next 1-minute bar's open.
Short rule
Same overlap-regime-transition + expansion condition, with bar i closing below its open (bearish): enter SHORT.
Entry trigger
High-overlap-regime-to-low-overlap directional expansion on a closed 5-minute bar, edge-detected: re-armed only once the high-overlap regime condition is next observed false, then true again, on a later closed 5-minute bar.
Earliest executable entry
Next 1-minute bar's open after the triggering 5-minute (transition) bar closes.
Initial stop
The transition bar's OWN opposite extreme: low of the transition bar for a long entry, high of the transition bar for a short entry.
Exit
FIXED_2R only (this seed strategy's declared A1 scope), via the shared TradeTracker; 5-day max-hold expiry as a backstop.
Causality
The high-overlap-regime average is computed only from closed 5-minute bars STRICTLY PRECEDING the trigger bar, and the ATR used for the expansion-magnitude check is likewise computed only from bars strictly before the trigger bar -- the trigger bar's own range never contaminates either baseline it is measured against. Entry is deferred to the next 1-minute bar's open after the trigger bar closes. No same-bar entry.

Parameters
overlapWindowBars5m = 10 (integer) — 5-minute bars over which the high-overlap-regime average is computed.highOverlapThreshold = 0.5 (number) — Average overlap fraction over the window must be at or above this to count as a compression regime.lowOverlapThreshold = 0.15 (number) — The trigger bar's own overlap with the prior bar must be at or below this.atrLength5m = 14 (integer) — 5-minute ATR lookback for the expansion-magnitude requirement.expansionAtrMultiple = 1.5 (number) — The trigger bar's own range must be at least this multiple of the preceding ATR.
