Start here: what FundedSim simulates and what it doesn't
FundedSim runs your trades through the real eval rules of Apex Trader Funding and Topstep: trailing drawdown (end of day or intraday), the daily loss limit, the 16:59 ET end-of-day settlement, contract limits and the profit target. Trade in the app with live prices or import your TradingView trades as a CSV.
What it does not do: it is not a broker, it does not send orders anywhere, and passing here does not get you a funded account. It is practice, so the mistakes cost nothing.
