Order request sometimes not being dispatched to server, causing trade timeout error. Could be a bug.

Each order operation request (OrderSend, OrderModify, OrderClose) goes through a number of stages, with the first steps being display of the details in the Journal log and the transmission of the request to the server. However, it often seems that the request is never dispatched, and the order

Alternative to IsConnected()

IsConnected() within a continuous loop seems to take around a minute to react to a lost connection. A timeout of execution of a submitted trade operation can take a few minutes to return to the client. These durations are too long. Are there any alternatives that would tell me in under 5s whether

Can a broker disable expert advisors?

Can a broker disable expert advisors? Does IsExpertEnabled() check whether the broker has enabled or disabled expert advisors? Or does it only check whether the user has enabled it in the terminal? Similarly, does IsTradeAllowed() check whether the broker has enabled or disabled trading in the

Price feed frozen - how to check for and handle in an Expert Advisor

I sometimes see that the price feed from a broker has stopped, only to resume a while later. Just in the last hour I saw that the price froze for around 6 minutes, base on the time in the MarketWatch pane. It's a demo account , and I presume that brokers may not worry as much as with live servers
