About this app

A hidden symbol at a hidden starting point, revealed one session at a time, with buy, sell, flat and step controls and a running equity curve. The newest bar is drawn well left of the canvas edge so there is visibly nothing to the right of it. Trades are marked on the chart and logged with their return. The argument it makes is not about the score: setups that look obvious in a screenshot are ambiguous while they are forming, and that ambiguity is the actual job.
