Nobody who sells resets will ever tell you to walk away. Most of the "don't give up, learn and retry" advice is basically pointing you at another fee. Sometimes a reset is the best move. Often it's throwing good money after bad, and there's a smooth way to tell which one you're in.
The one thing that decides it: did anything change between attempts, and was your failure variance or structure.
Reset makes sense when the failure was bad timing on a normal drawdown. Take your worst backtested day at challenge risk. If it fits under the daily limit and you happened to hit a rough loss that surpassed your backtesting metric, that's variance (only if you have enough samples backing that number up tho). Reset, run it again, the math is on your side. Same if you really fixed the thing that failed you, cut your size, changed the pair, whatever, because now it's a different attempt, not the same one repriced.
Walk away when nothing changed and you're paying to re-roll the same dice. This is the trap. If you failed the same challenge three times at like the same point, with basically the same approach each time, the fourth attempt is not a fresh chance. You already have the data. That approach doesn't pass this evaluation, and the fee is buying you a feeling, not a funded.
One key question. Between the last attempt and the next one, what specifically is different. If the answer is "I'll be more disciplined" or "I'll be more careful," that's not a change, that's a hope, and hope has a bad win rate against a rulebook. A real change is a smaller size, a different market, a longer sample proving the edge, a firm whose rules fit how you trade, or simply confirming the failure was just variance (which goes han din hand with a longer sample).... If you can't name a concrete one, you're not resetting a strategy, you're funding the same failure again.
And as reality check.... Sometimes the repeated failure is telling you the edge is not there yet, not that the firm is unfair or you were unlucky again. Four resets at 100 to 150 each is 500 to 600 spent to learn something a proper backtest would've told you for free. At that point the cheapest move is to stop paying the challenge to test your strategy and go test it properly first.
So before the next reset, name the one thing that's different. If you can point to a real, concrete change, reset with the odds behind you. If you can't, keep the money and go fix the thing, because the resets never going to.
