The six Lab checks.
| Check | Result | What we found |
|---|---|---|
| 01Real ticks | CAUTION | It reproduces on real ticks with 80 trades against the author’s 79, but for +$425.32 against the advertised +$589.34. Renko bricks built from ticks differ from broker to broker. |
| 02Out-of-sample | FAIL | January 2025 to May 2026 lost $338.94 at a profit factor of 0.94 over 389 trades. |
| 03Live and verified | NOT ASSESSED | Backtests only. This verdict rests on the Lab’s own tests, not on a live account. |
| 04Real costs | PASS | About $10 of spread and commission across 80 trades. Costs are not the problem. |
| 05Robustness | FAIL | Starting the test a few sessions later turns +$425 into a $323 loss. Brick size 21 is an isolated spike, and only 10 of 25 variants finish above zero. |
| 06Integrity | CAUTION | Symmetric, one position at a time, a real stop-loss and no martingale. But the advertised 1.18% drawdown comes from 0.01 lot on $10,000, about 0.4 times leverage. |
What we measured.

1 May to 24 August 2026: profit factor 1.72, against the advertised +$589.34 at 2.27.
- Out-of-sample−$338.94
January 2025 to May 2026: profit factor 0.94 over 389 trades.
- Full 20 months−$264.89

- Start date moved−$323
