Supply Scout on Micro Dow (MYM)
Should you use it?
Use with cautionUsable, with caveats
It meets the brief on MYM, but read the caveats before trading it — and run it in simulation first.
- Stayed profitable going forward at 4 of 4 walk-forward cut-offs.
- Would have been picked in advance at only 1 of 4 cut-offs — the edge was found with the whole period in view.
- An isolated optimum: neighbouring stop/target settings don't pass, so small drifts could break it.

What the numbers say
- It meets the brief. Target: profit factor above 1.0 and at least 3 : 1 net profit to max drawdown. Result (NT8 Strategy Analyzer, with the “NinjaTrader Brokerage Free” commission template): PF 1.29 and 4.6 : 1 on 299 trades.
- Profitable in every calendar year of the test (2024: +$218, 2025: +$1,134, 2026: +$556); 15 of 26 months positive; best 2025-10 (+$546), worst 2026-03 (−$188).
- Long / short split. Longs +$654 on 147 trades, shorts +$1,267 on 152.
- Exposure. Average 64 minutes in the market, 0.6 trades per session; every trade closed within the Globex session it was opened in (18 at the 15:55 flatten, 3 at the 17:00 session close), nothing carried across the 17:00 break or a roll.
- Walk-forward. The in-sample winner failed forward at 4 of 4 cut-offs. The recommended set was positive forward at 4 of 4 cut-offs (forward PF 1.27–1.43, net/DD 1.4–4.0) and would have passed the in-sample gate at 1 of 4 of them — positive forward but not something an earlier search would have selected.
- Plateau. 2 of 72 stop/target cells in the same family pass PF > 1 and net/DD ≥ 3 over the full period — an isolated optimum.
- Verified. The replica behind the sweep matched NT8’s trade count on the validation window (279 vs 279); headline figures come from NT8’s own engine.

How robust is it?
Walk-forward check
The in-sample winner held up forward at 0 of 4 cut-offs; the recommended set was positive forward at 4 of 4 and would have passed the gate at 1 of 4. It works forward but was identified with the whole period in view — discount the headline accordingly.
Monte Carlo
The observed drawdown ($408) sits at the low end of what the same daily results could have produced — 78% of resampled histories draw down further, and 1 in 20 reaches $936 or more. The edge is not in doubt in this sample: 1.4% of resampled histories end below zero and the 3 : 1 brief holds in 59% of them. Reordering the same trades (second row) moves the drawdown a lot: the 95th-percentile sequence-risk drawdown is $950. Size the account on the 95th-percentile drawdown ($936 per contract) plus margin, not on the observed $408, and expect up to 162 trading days without a new equity high.

Know before you trade it
- Selection bias. 105,840 configurations were searched; the walk-forward is the only evidence not contaminated by the search. The recommended set was positive forward but earlier searches would not have chosen it.
- Plateau width. 2 of 72 neighbouring stop/target cells pass — the set is an isolated optimum and should be treated as unproven.
- Instrument-specific. Stops and targets are in MYM ticks; do not transfer them to another instrument — each instrument has its own report.
- Fill assumptions. Both engines fill stops at the stop price and targets on touch; live fills will be worse.
- Two years, one regime. The sample is Aug 2024 → Sep 2026; behaviour in other regimes is untested.
Getting started
- Run it in simulation first with the inputs above and compare the first 100–200 trades against the forward statistics before any live size.
- Do not chase the leaderboard. Re-optimising to whatever tops the in-sample ranking is the procedure the walk-forward check shows failing.
