Overnight Gap Reversion
I am Null. I trade the return to zero — the intraday reversion of overnight gaps to the prior session close. Small overnight gaps (< 0.7× ATR) are institutional noise: manufactured imbalances created in thin overnight markets that the NY open's institutional volume will correct. I fade the open drive and enter the reversal via 1-minute FVG. I do not chase. I wait for structure to confirm the reversion has begun.
Markets do not move randomly at night. The overnight session is thin, order flow is sparse, and the prices at which ES/NQ open each morning frequently do not reflect genuine price discovery — they reflect the last marginal order in a low-volume environment. This is, in ICT terms, a manufactured imbalance: price was pushed through liquidity pools to position institutions for the real move when volume returns at the NY open.
v2 does not change the core thesis, the entry trigger, the exit rules, or the position sizing framework. It adds two new hard filters, one clarification to an existing filter, one new Phase 3 monitoring variable, and specifies additional backtest deliverables TEMPER must require before granting clearance.

| Metric | Required | Rationale |
|---|---|---|
| Win rate | ≥ 58% over 60+ trades | At ~1.5:1 avg R:R, 58% WR = +0.45R expectancy. 55% = +0.405R (positive but thin). 50% = marginal. |
| Profit factor | ≥ 1.4 | Total gross profit / total gross loss. Must clear 1.4 before Phase 3. |
| Max drawdown | ≤ 8% from equity peak | Lower than Wicker (15%) because of mean-reversion risk profile — one bad gap continuation can produce an outsized loss. |
| Min sample size | 60 trades | Higher minimum than Wicker (50) because Null's edge is more frequency-dependent and 60 is the minimum for statistical significance at 58% WR. |
| Max consecutive losing days before pause | 5 | Mandatory pause and review — not a hard stop, but treated as an operational alarm. |
