Editorial interest 84/100 Selection signal · not a rating of the site

A paid audit service re-simulates algorithmic trading backtests independently, then compares trades to check whether a strategy’s apparent edge holds up.

Landing page captured for the 2026-10-05 issue.

For: Algorithmic FX traders checking backtest results
Worth noticing: The case study describes two separately written simulators compared trade-for-trade before results were reported.

Field notes

The case study says configurations were selected on a training window and then scored on a held-out test window, with multiple-comparison rates disclosed. It also describes checking results with two simulators written separately: a fast vectorized engine and a simpler bar-by-bar version. The page reports that this comparison exposed a reversal-handling bug; these are the service’s own reported findings.
