On Live account, faced too many problems with the Orders Execution for opening & closing. Can take easily 5 seconds and click on average 3 times on the Buy/Sell or close bottom before it takes into consideration.
Also, had more than 1 time server problems when I was in trades... very frustrating !
Have reported all of these to the Customer Service (I am considered to be a VIP customer), and only a kind of 'sorry' came back with no solution and so far, nothing has improved.
Execution and server are very important points as you can loose money !
