If I am in a margin warning, what happens if the market moves back in my favor?

There will be a daily maintenance margin check at 17:00 ET. If the market has moved back in your favor at that time such that your Usable Maintenance Margin (Usble Maint Mr) is greater than 0, your Margin Status will be reset (MC = N). You may contact FXCM’s service or trading desks if you wish to have your margin reset earlier.

Once your account status is reset, your account will no longer be on ‘close only’ and you will be able to place new positions provided you have enough available margin in your account.
