To Keitsuke :
Congratulations!!
A word of strong counsel :
For the first 10 or so trades, trade the smallest amount you can.
This is so that you can "practise" live trading.
Be prepared for
slippage.
Be prepared for the entries and exits to take longer than on a demo.
Be prepared for screen freezing.
Keep a sharp watch on your floating profit/loss.
I am not saying that the above problems will occur but be prepared just in case.
Also very important - know how the "re-login" function works in case you need it.
