Copy trading, hedging and shared devices: the prop firm rules that aren’t about numbers

Some payouts are refused because of how you traded, not how much. These rules vary between firms more than any other kind, so read them before you connect a trade copier or open a second account.

We read six well-known futures firms’ own rules and help pages in September 2026. No firm is named here. Rules change, so check your firm’s current page.

1. Hedging: banned everywhere we looked

Every firm we read bans hedging. What counts as hedging is where they differ:

• long in one of your accounts and short in another, in the same market;
• opposite positions in the mini and micro of the same market;
• at one firm, even opposite positions in related markets, such as long one stock index and short another.

If you trade several accounts, the safe habit is simple: every account in the same direction, always.

2. Copying your own trades: the biggest difference

• Allowed: one firm says you can copy between your own accounts there, and even to accounts at other firms, as long as every account is yours and verified in your name.
• Banned: another firm bans trade copiers for passing several accounts, and after you pass.
• Not said: most firms’ pages don’t say either way. One firm’s own pages disagree with each other.

A useful clue: if a firm builds a trade copier into its own platform, copying between your own accounts there is clearly expected. Copying across firms, through an outside copier, is the part to confirm.

3. Other people: the firm line

Across the firms we read, these are banned: copying someone else’s trades, trading as a group, trading an account for someone else, and sharing your login. Each firm words it differently, and not every page lists every one, but none allowed them. Some go further: no using the same computer or phone as another trader, no VPNs, or logging in from consistent internet addresses unless you’ve asked.

4. Trading styles

None of the pages we read set a minimum time a trade must stay open. Some banned specific styles instead: high-frequency trading, exploiting unrealistic fills, trading certain news releases, or holding positions too close to the session close.

Why these rules exist

They stop one person hedging across accounts so one of them is guaranteed to pay, and they stop accounts being passed by someone other than the owner. Read that way, they protect the traders who pass on their own.

Before you connect a copier

1. Read your firm’s prohibited-conduct page, not just the drawdown and target.
2. Ask in writing, for example: “Is copying my own trades across my own accounts allowed, including across different firms?” Save the answer.
3. Save a dated copy of the rules the day you buy. Here’s how.
4. Remember the maths too: five copied accounts at 2 contracts is 10 contracts on the same trade. The position size calculator includes the copied-account multiplier.

Educational material only. Not investment advice. Trading futures involves substantial risk of loss and most people who try it lose money. Check your account rules with your firm; they change.
