Data preparation
We assemble survivorship-free data, apply corporate actions and validate every series.
Strategy build
Your rules are coded independently and checked line-by-line against your description.
Testing & robustness
In-sample, out-of-sample, walk-forward, parameter sensitivity and Monte Carlo resampling.
Report & review call
You receive the PDF, data files and code notes, followed by a call to walk through results.

Common biases we check for
Look-ahead
Using information that wasn’t available at the time of the trade.
Survivorship
Testing only on companies that still exist today.
Overfitting
Tuning parameters until noise looks like signal.
Cost blindness
Ignoring commissions, spreads, slippage and borrow fees.
