A reader sent us a paid TradingView opening-range-breakout strategy — the kind sold with a glowing equity curve and one giant number on the sales page: 76% win rate. It looked more profitable than the system we'd spent weeks building and gate-testing. So we exported its full one-year trade log — 331 trades on NASDAQ micro futures — and did what nobody does before buying: read it.
| What's advertised | What the log says | |
|---|---|---|
| Win rate | 76.4% | real — but keep reading |
| Average winner | — | +23.5 points |
| Average loser | — | −69.6 points |
| Profit factor | — | 1.10 |
| Year's profit | $2,875 | …trading up to 12 contracts |
| Profit per contract | — | $3.10 per trade |
| Commission column | — | $0.00, all 331 rows |
| Max drawdown | — | $2,853 — as large as the profit |
Win 76% of the time, win small, and lose three times bigger when you lose. That's not an edge with a high win rate; it's the win rate purchased from the edge — the exact inversion we demonstrated in part 4, running in a paid product.
331 trades at an average of ~3.4 contracts is roughly 1,100 contract round-trips. At realistic micro-futures costs that's about $1,950 in commissions and exchange fees the backtest never paid. Subtract it and the year's $2,875 becomes roughly $900 — before slippage, which at this trade frequency comfortably erases the rest. The honest expectation of this strategy is approximately zero, presented as a winner by a checkbox left unticked.
196 of 331 trades — 59% — enter and exit inside the same five-minute candle. Backtesting platforms fill same-bar entries and exits at optimistic intrabar prices that no live order flow guarantees; it's the least falsifiable fill assumption in retail backtesting. When most of a system's trades live in that zone, the equity curve isn't evidence — it's rendering.
Position sizes swing from 1 to 12 contracts with no stated rule — and the biggest sizes cluster after losing streaks. Whatever the intent, on a prop account that pattern has a name: one of its −70-point losses at size 12 is a −$1,680 day, an instant daily-loss-limit violation at most firms. A strategy can be harmless in a vacuum and undeployable inside the rules you'd actually trade under.
Strip the presentation away and the vendor's system made independent, real-money-adjacent choices we had tested and rejected on seven years of data: a shorter opening range (our data ranks it below 20–30 minutes), always trading both directions (fails selection tests), and profit-taking tuned for win rate (the part-4 trap). The audit didn't just fail their strategy — it out-of-sample confirmed our graveyard. Every grave got a second flower.
The uncomfortable economics: a 76% win rate with a green curve will outsell a 51% win rate with honest gates every single time. Which is why this series exists. Audit the log. It's always in the log.
