Start with one question below. For a full strategy run, use the personal rules simulator or the prop firm simulator. No firm is needed when the limits are your own. The portfolio rebalancing calculator turns entered holding values and target weights into sell-and-buy trades or a no-sales cash plan.
Choose by the answer you need.
Size a position, or find the capital implied by a fixed dollar-risk amount.
See how different win/loss sequences meet the limits you enter.
Calculate the climb back, or inspect a floor against an equity path.
Test your strategy against your own limits or a published rule set.
Different jobs, different models. The trailing-floor trace compares static, end-of-day, intraday and closed-trade modes on one event path. Its separate optional Monte Carlo widget, like the personal-rule widgets, uses a static floor. Calculator inputs do not transfer automatically between tools. A modeled result is not a forecast or a recommended risk level.
