The consistency rule explained

Your single best trading day can't exceed a set percentage of your total profit — 40% on the Acid Easy evaluation, 20% on Acid Instant, and none on a funded Acid Easy account.

Example at 40%: if your total profit is $2,000, no single day may contribute more than $800. It rewards steady, repeatable trading. Breaching it delays a pass/payout until your profit distribution comes back into range — it doesn't fail your account.
