I can't open more than four positions at a time.
I have noticed some people can open more than four trades same time with very low equity while I can't open with higher equity.
I'm just trading 1 mil standard lot with 4 different pairs while it shows that I still have 14 mil Free Trading Line; however, system rejects any new positions after four.
This is the message, pls take a look:
14:45:36 Your order has been rejected due to validation failure. Open positions/ entry orders limit reached. To enable new positions/ entry orders, respective number of existing positions/ entry orders must be merged/ closed/ canceled.

I don't know what the rules are, but I am only able to have 5 trades at any one time. That is a combination of open and pending trades.

Note that not only open positions are counted, but pending entry orders as well. Hence, you won't be allowed to open new positions or set new entry orders when having 4 open positions and 1 pending order.

Thanks Dukas; I see, I had a pending order; that explains the rule
