I request @ZuluTradersDesk to note the following observations concerning US Compliant Trader Accounts:
A trader that strictly follows one trade FIFO standard with a maximum of only one opened position obviously meets the US Trader Accounts Compliance requirement. However, it appears this is not the case. ZuluTrade system seems to penalize an account when a pending order is closed at the same time with an active position as seen in the MT4 snapshot below on 2020.01.21 11:10:00.
The Account name is: FIFO 1 Model
This account was removed from the US list. This appears to be an error that should be corrected by @ZuluTradersDesk.
