Seven mistakes that end prop firm accounts

These seven errors explain most account closures. All are preventable.

1. Oversizing

Large trades to reach target fast: the top cause of failure. Keep risk small and constant.

Treating trailing as static, or ignoring floating losses. See the drawdown guide.

Opening or closing inside a banned window can void profit or breach the account.

Copying others or hedging across accounts/firms is prohibited almost universally.

Server-time resets can put losses either side of local midnight into one trading day.

Commercial bots often violate hold-time or HFT rules. Get written approval first.

After a loss, stop. Need does not improve the next trade.

Refunds for accidental breaches?

Almost never; some firms offer discounted retries.

Warning before closure?

No; hard breaches typically close accounts automatically.
