Starting Line
The liquidation line starts at starting balance - trailing amount. If your equity ever drops below that line, the account is considered blown.

How This Simulator Treats Trailing Drawdown
Trailing Logic
After each trade, the high-water mark (max equity) is updated. The trailing line is set to high-water mark - trailing amount, subject to the cap rule you choose.
Illustrative Starting-Balance Cap
In the capped mode, the simulated line never moves above the starting balance. This is a generic mathematical option, not a representation of Apex or any other provider's current rule. Verify the plan, stage, high-water input, update frequency, cap, breach comparison, and fees in the provider's live documentation.
Model scope and rule sources
The calculator processes one completed trade P/L value at a time. It does not model intratrade equity highs, commissions unless included in each input, daily-loss limits, consistency rules, resets, liquidation latency, or provider-specific stage transitions.
- My Funded Futures intraday drawdown explanation and end-of-day drawdown explanation, reviewed September 19, 2026, illustrate why update clocks and high-water inputs must be explicit.
- Topstep Trading Combine parameters, reviewed September 19, 2026, provide a separate current rule example and demonstrate that provider terminology and breach comparisons vary.
Examples are educational. Provider rules change; use the provider's current written terms and dashboard threshold for an operational decision.
