If you click on positions < Missed, there will be an explanation for every missed trade. Such as not enough money in balance, Market not available etc.
Our system works by sending out the request for a trade to be placed and then waits for a response from the broker server. This is usually instantaneous but we will wait for as long as 15 minutes. If the trade remains within the price parameters set by the signal, the trade will be executed within those 15 minutes. After 15 minutes the trade will not be copied. This is why your trade execution could be late or missed.
