Is there an inactivity rule?
Updated
Funded accounts must stay active. Place at least one trade in any rolling 15-day period. If 15 calendar days pass without a trade, your funded account can be deactivated.
The rule only applies to funded accounts. There's no inactivity rule during the evaluation, though the 120-day time limit still applies.
Going on a break
If you'll be away, message support before your break starts. As long as you've told us in advance, your funded account won't be deactivated for inactivity while you're away.
