A GM strategy you can build in minutes

Snap a data source brick set to GM, add an entry (e.g. an RSI dip or a moving-average cross), a stop and target, and run it. TradeBricks splits the data into a development window and an unseen holdout, so a strategy that only looks good in-sample gets flagged as overfit instead of fooling you.
