The walk-forward lab is now open. You send a compiled expert advisor or the source code, we run rolling in-sample optimisation with out-of-sample validation and return a report you can actually act on.
The report includes walk-forward efficiency per window, parameter stability heatmaps that show whether the profitable region is a plateau or a single lucky cell, and Monte Carlo equity cones built by reshuffling trade order and slippage.
We also check the boring things that kill live results: spread and commission sensitivity, tick modelling quality, trade count per window and behaviour around session gaps and rollovers.
Turnaround is usually three to five business days depending on the parameter space. Request a slot through the contact form and describe the strategy, symbols and timeframes you trade.
