Paste your real per-trade results in R (a 2.3R winner, a full -1 loss, a -0.6partial, and so on). The sim resamples them in blocks so your actual losing streaks stay intact, instead of assuming every trade is independent. The win rate and R above are read from these while they’re here. 8+ trades needed.

Challenge verdict

Good odds — held back by a thin, uncertain sample.

Held to B: the odds rest on a thin sample — more trades would firm it up.

Risk 0.90% (~$900) per trade gives the best raw odds — 86% of simulated attempts pass. But you don't need to size that big: 0.80% (~$800) passes 84% of the time — nearly the same — for less blow-up risk. Over-sizing rarely buys better odds; it mostly raises the chance of a breach.

Best-odds pass rate is 86% on your point estimate, 16% at the low end of a 50-trade sample. The tighter that gap, the more your sample backs the number.

How The5ers’s rules shape your sizing

Most The5ersaccounts don’t fail on strategy — they fail on the 10% max drawdown or the 5% daily loss limit, usually from three to five oversized trades. The calculator above sweeps every position size against those exact limits and the 8% target, then shows the one with the highest odds of clearing the challenge. The honest answer is almost always smaller than traders expect — which is the whole point of checking before you pay the fee.

§ The5ers questions

What lot size should I use for The5ers?

There's no single number — the safe size depends on your win rate and reward:risk. The free calculator above runs thousands of simulated The5ers attempts against its 10% max drawdown and 5% daily loss limit and returns the position size with the best odds of passing, plus a leaner size with nearly the same odds. It's almost always smaller than traders expect.

What is The5ers's max drawdown and daily loss limit?

The5ers's evaluation uses a 10% overall drawdown and a 5% daily loss limit, with a 8% profit target across 4 account sizes ($5k, $10k, $20k, $100k). The full, source-dated rulebook breaks down all 14 encoded rules.

Does The5ers allow EAs or automated trading?

Yes — The5ers is algo-friendly, so EAs and automated strategies are allowed on the evaluation.
