The quiet
account-killer

A firm can have a perfect drawdown model and still be useless to a tick scalper. Many of the friendliest EOD firms quietly pair that forgiveness with an anti-scalp or minimum-hold rule. Miss it and your profits get voided after the fact.

If you trade 2–8 tick targets on ES, your holding time is often measured in seconds. That puts you squarely in the zone several firms police. The rules come in a few flavours — and the wording matters, because enforcement is usually pattern-based, not a single-trade trip-wire.

01The four rule patterns

Why it's dangerous
These rules are often enforced at payout time, retroactively. You can pass, trade for weeks, then have profits voided because the account review flags your holding-time profile. Check before you fund — not after.

02How firms tend to land

Scalp-fitWhat it meansTypical profile
CleanScalping allowed, no relevant minimum-hold ruleSub-second flags only on extreme cases (e.g. <5s generating most profit)
GreyScalping fine, but micro-scalp (~≤15s) banned as a core strategyWorkable if your average hold clears the threshold — measure it
RiskHard rule that bites a tick profilePercentage-held rules, or explicit tick+time bans, or no-100+-trades caps

The pattern worth internalising: the newer, EOD-friendly firms are the ones most likely to attach a scalp constraint, because the forgiving drawdown is balanced by tighter behavioural rules. The cleanest scalp-fit often sits with the more established futures-native firms.

03How to protect yourself

Bottom line
Drawdown decides whether you survive; scalp-fit decides whether you're even allowed to play your game. Treat it as a kill-criterion equal to drawdown, not an afterthought.

Every firm on the index carries a colour-coded scalp-fit tag — green, amber, or red — so you can filter out the rules that would void your style.
