Equity curve split by account: bands, purchase lines and cash tally
The prop firm simulation draws the backtest equity curve as a sequence of account bands, one per evaluation bought, so you can see which part of the curve belongs to which account and how each one ended.

Where to find it
- Where
- Replay → Previous sessions → "Prop firm simulation" tab → section "Equity curve, split by account"
- Input
- The lifecycle events emitted by the simulation engine (sequential or parallel) and the closed trades of the backtest
- Requires
- At least two closed trades and a saved rule set to simulate against
What it does
A backtest equity curve behaves like a single live account: it never resets. A prop firm account does. When an account dies at the bottom of a drawdown, the next evaluation starts again at its own initial balance, not at the level where the curve currently sits. The recovery that only looks like a return to break-even on the continuous curve is, for the new account, a full gain that can pass its evaluation. The reverse is also true: a curve in profit can hide an account that has just breached its floor.
This panel makes that visible. It keeps the cumulative P&L curve of the backtest and overlays one band per account: a vertical dashed line at each evaluation purchase, a tinted band from the purchase session to the session where the account died, and a lighter line where the evaluation was passed, which is the boundary between risking the fee and trading funded capital. An account still alive when the sessions run out extends to the right edge of the drawing.
Nothing is recomputed here. The panel re-reads the events already emitted by the lifecycle engine (EVALUATION_PURCHASED, ACTIVATION_PAID, EVALUATION_PASSED, EVALUATION_FAILED, FUNDED_FAILED, PAYOUT_PAID) so the drawing cannot diverge from the numbers shown elsewhere in the report.
Legend and tally
| Element | Default | Meaning |
|---|---|---|
| Dashed vertical line | One per purchase | Marks where a new account restarts from its initial balance |
| Band "Eval lost" | Tint per outcome | Account that failed during evaluation |
| Band "Funded lost" | Tint per outcome | Funded account that breached its floor |
| Band "Still open" | Tint per outcome | Account alive when the sessions ran out; counted neither as passed nor failed |
| Lighter line "passed on" | Only if passed | Session where the evaluation was passed |
| bought / funded / paid out | Counters | Accounts purchased, accounts that passed, accounts that received at least one payout |
| hit the max DD | Counter | Accounts whose breach reason was MAX_DRAWDOWN, in either phase; daily-loss or consistency deaths are not counted here |
| cashed in / spent | Money | Net payouts received versus purchases plus activation fees |
How to use it
Hover a band to read its tooltip: account number, start and end session, the session it passed on, the number and total of payouts, and the breach reason when it died. Compare the number of bands against the counters: many short bands ending on the drawdown line mean the strategy spends most of its fees before ever reaching a funded phase.
Read the tally, not the curve, when you want to know what was actually collected. The net P&L of the curve includes evaluation profits that are never paid out and funded profit that died with its account. The cash-flow engine that feeds this tally only adds the cash field of each event, which is what lets the same path be replayed against another firm's fee schedule.
Limits and pitfalls
- Band positions are placed at day precision: a session label is compared with midnight UTC while a CME session opens the evening before at 17:00 Chicago time. The offset is a few hours and only affects where a band edge lands on a curve spanning weeks.
- The panel needs at least two closed trades and a measured width; with fewer trades only the counters are shown.
- In the parallel lifecycle, accounts opened on the same day receive the same P&L series and die together for the same reason. That is copy trading, not diversification, and the bands will overlap accordingly.
- This is a simulation over past trades and a rule set you entered. It does not certify how a firm applies its rules and promises nothing about future results.

Frequently asked questions
- Why does an account pass while the overall curve is only back to break-even?
- Because the new account started at its own initial balance when the previous one died. On the continuous curve the move looks like recovery; for that account it is a full gain measured from its own start.
- Why is the "cashed in" figure so different from the net P&L of the curve?
- Payouts are per account and every account cost its purchase and activation fee. Evaluation profit and any funded profit that was never withdrawn are not cash; the tally separates what was received from what was spent.
- Is an account still open at the end counted as a failure?
- No. It is shown as "Still open" and excluded from the pass rate, because counting it as failed would lower the pass rate as the tested period gets shorter.
