About this app

Builds a track record from a win rate, average win and loss, and a spread, then resamples it with replacement four thousand times to produce a distribution of expectancies with a 95% interval, plotted as a histogram against zero. Reports the share of resamples that come out negative — frequently large for a record that looks convincing — and computes the number of trades that would actually be needed for the interval to exclude zero, which is usually thousands rather than dozens.
