The missed trades tab on the positions page will give you a reason as to why the trade was missed.
Also we suggest you check whether your max drawdown has been triggered by navigating to Account and checking your Max drawdown status.
If this has been triggered, either reset your drawdown or add further funds to your wallet. Secondly check whether your account has enough funds in.
