Hi Nchele,
The various prop firms will open and close the FTMO robots differently. You didn’t specify how long you have been trading with these various prop firms but in my opinion you just need to give the robots more time to place trades.
My advise when looking to use other prop firms is to first test them out with a minimum account to see how the FTMO robots perform before opening larger accounts. If possible chose 3 or 4 prop firms, place the same robots with small lot size and test them for a month or two then pick the best performing one to open larger account. Test, test, test, before opening large accounts.
Alan,
