Enter the plan once, then open the five plan-aware calculation and review tools with matching context.
Plan data stays in the URL fragment and is not sent as part of the page request. The workspace does not save these plan values. Backtest receives equity only; replay opens a clearly labeled planned-stop scenario that must be replaced with actual execution data after a completed trade.
