If it receives an requote or slippage error while opening, it will retry again 6 times with an short time delay between the last 2 try's and the 1st 4. When closing, it will keep trying until it closes, does not matter what error it receive. So dont worry to much about that
Ive made some changes to the ea, added an closeall option and fixed the current draw down display to correctly display 2 decimals. Ive updated that post where I attached the ea.
