Why do I receive a message "Your order has been rejected due to validation failure. Open positions/ entry orders limit reached"?
According to the contest rules, the participant can maintain only 1 open position group. Any further requests to open a new position or place a pending order will be rejected.
And you can not open more than 5 positions at once. I can not find this rule in the contest rules about the 5 position maximum but it gives the same message.
