About PropFitt
PropFitt is a risk manager built for traders taking prop firm challenges. It keeps every challenge, phase and rule set in one place, and answers the only question that matters before you click buy: how much can I risk on this trade without breaking the account?
From evaluation phases through to funded trading, PropFitt tracks your balance curve, drawdown usage and daily loss limits in real time. Our purpose is simple — help traders protect their drawdown while making informed, repeatable risk decisions instead of guessing.
The drawdown survival model turns your remaining drawdown budget and losing-streak history into a concrete risk per trade, recalculated after every result.
Static, trailing and end-of-day drawdown rules, plus daily loss limits, are translated into a live remaining budget so a breach never comes as a surprise.
Pass probability, risk of ruin and wins-to-pass sizing come from calibrated simulations of your own trading edge and your challenge rules.
