Drift worst day vs the daily limit: four tracks, one $5,000 line
Drift's worst day over eighteen months was $1,750 on NAS, 35% of a $5,000 daily loss limit; XAU used 30%, MGC 18%, MNQ 11% (source: PV_EDGE Master Data, modeled Apr 2025 – Mar 2026, live Apr – Sep 2026). None of the four crossed half the limit on any day.
Why read the worst day before the net?
Because a prop firm account ends on one bad day, not on one bad quarter. A track that earns well but spends 80% of the limit on its worst day is a track that will eventually spend 100%. Drift's largest single day used 35%, which leaves room for the other families on the same account to have their worst day too.
What does a fixed-schedule exit do for the worst day?
It caps exposure in time. Every Drift track closes on a fixed schedule, so a position cannot run through a session it was never meant to hold. A schedule isn't a prediction of the day; it's a cap on how long the account is exposed, and that is what makes the worst day a number you can plan around.
How does the limit work on the Index?
On the PVE Index Forex version, with all 16 tracks on one 100K swing account, the worst live day was $1,469 against the same $5,000 limit, 29%. The mechanics of the limit itself are in prop firm daily loss limit explained, and the full Drift write-up is in Drift: the newest strategy family.

FAQ
Is 35% of the limit a lot? It leaves 65% of the day for every other track on the account. Inside the Index, worst days don't all land on the same date, which is why the Index's own worst live day is 29%.
Does the worst day change when weights are recalculated? The dollar figure per track at its 100K preset doesn't. Its contribution inside the Index does, because the weight does.
