Free prop firm challenge simulator
Rehearse a funded-trader evaluation before you pay for one. BackForFree replays real market data candle by candle and enforces the same kind of rules prop firms use: a profit target, a trailing or static drawdown, a daily loss limit, position limits, minimum trading days and a consistency rule. No account, no card.
How it works
- Pick an evaluation. A futures account tier or a percentage-based program, with its profit target, drawdown and daily loss limit.
- Pick a market and dates. Choose a start and end date (or a random one so you can't remember what happened). The chart is cut at the start; the future stays hidden.
- Trade the replay. Step one 1-minute bar at a time or play at 1x–10x. Market, limit and stop orders, optional stop loss and take profit you can drag on the chart.
- Pass or fail honestly. Break a rule and the account is liquidated at the exact price, like a real evaluation. Hit the target with enough trading days and consistency and you pass.
Futures evaluation rules
| Account | Profit target | Trailing drawdown | Daily loss limit | Max position |
|---|---|---|---|---|
| $25K | $1,500 | $1,500 | $500 | 2 Minis / 20 Micros |
| $50K | $3,000 | $2,000 | $1,000 | 5 Minis / 50 Micros |
| $100K | $6,000 | $3,000 | $2,000 | 10 Minis / 100 Micros |
Every futures account needs at least 2 trading days, and your best day may be at most 50% of total profit (consistency rule). You choose intraday or end-of-day trailing drawdown; both lock at the starting balance.
Percentage-based programs (forex, gold, indices, crypto)
| Program | Profit target | Daily loss | Max loss | Min days |
|---|---|---|---|---|
| Two-Step · Phase 1 | 10% | 5% | 10% static | 4 |
| Two-Step · Phase 2 | 5% | 5% | 10% static | 4 |
| One-Step | 10% | 3% | 6% trailing (end of day) | 1 (best day ≤ 50%) |
Account sizes: $10K, $25K, $50K, $100K or $200K.
No look-ahead
Higher-timeframe candles (5m, 15m, 1H, 4H, daily) are built minute by minute from the bars you have already seen, and the 40 indicators only ever use those bars. Inside a 1-minute candle, fills follow a fixed path: a rising candle goes Open → Low → High → Close, a falling one Open → High → Low → Close. Stops and market orders take your chosen slippage; limits and take-profits fill at their price.

Is it the same as a real evaluation?
No simulator can promise that. Real fills, liquidity and each firm's exact rules differ. BackForFree is for practising discipline, testing a plan against hard limits and learning how drawdown rules behave before money is on the line. It is not affiliated with any prop firm.
