The sticker price of an evaluation is one monthly fee. The real price is that fee times the attempts it takes you to pass — plus resets and activation. Put in your numbers and see the cost you're actually signing up for.
Everything hinges on the per-attempt pass rate — and it's lower than most traders assume, because eval rules (a trailing drawdown, a daily loss cap, a consistency rule) fail strategies that are genuinely profitable in the long run. With pass probability p, you should expect about 1/p attempts on average: 50% → 2 attempts, 30% → 3.3, 20% → 5. And roughly 1 in 4 traders will need more attempts than that — the "bad-luck" column below.
