The real reason most traders fail prop firm challenges (it's not their strategy)
I've watched dozens of traders blow prop firm evaluations trading perpetual futures, and it's almost never because their entries were bad.
It's this sequence, every time:
Take a loss early in the day
Feel behind, increase size to "make it back"
Take a second loss, now emotional
Breach the daily drawdown rule on trade 3 or 4
The fix isn't a better indicator. It's a hard rule: 3 losing trades = done for the day, no exceptions. And your position size should be calculated backwards from your max daily drawdown, not from how confident you feel about the setup.
On a $50k account with a 5% daily drawdown ($2,500), that's roughly $625 max risk per trade if you want room for 4 losses before breaching. Most people size way bigger than that and have zero margin for a bad morning.
If you're prepping for a perp futures challenge, get the math right before you touch the strategy. Happy to answer questions on drawdown math or challenge rules in the comments.
