1% risk or 0.5% risk on a challenge with a 10% max drawdown?"

0.5% for me. Ten losses in a row at 1% puts you about 9.6% down, which is almost at the limit. At 0.5%, the same streak costs about 4.9%, so you still have room to recover. Yes, the target takes longer, but surviving a bad streak matters more than finishing fast. What do you use?"
