Chart Replay

How Chart Replay works

You see 100 days of history. Wait (or the → key) reveals the next few trading days one at a time, and stops early when something happens: a fill, an exit, or a setup worth a look. You never have to enter: waiting for confirmation is a real decision. To enter, choose Go long or Go short, tap your stop on the chart, then tap a target or skip it. The red box is what you risk and the green box is your reward; drag either handle to adjust them, before or after the fill. Moving a target farther when the chart supports a bigger move is fine; widening a stop costs discipline.

Orders fill at the next day's open, and position size is calculated so that hitting your stop costs exactly your chosen risk (0.5%, 1% or 2% of the account). Full Port instead puts the whole account into the trade: the screen glows green or red with your account, there are no hints, Auto-play only runs while you're in a trade, and every Wait costs 10 discipline points on top of the 25 each Full Port trade costs.

Stops and targets fill at their price during the day, or at the open if price gaps through them. If a day touches both, the stop is assumed to fill first. That's the conservative assumption real backtests use.

Scoring

Score = (1,000 + 200 × total R) × discipline%. An R is one unit of the risk you planned, so +3R means you made three times what you risked. Discipline drops when you move a stop further away, plan trades under 1.5:1 reward:risk, go Full Port, or overtrade. You'll also see how you did against simply buying and holding the same 60 days.
