Why orders get cancelled?

Hi,
Obviously noobish question here.. pardon me
Mostly trying to understand if there is any risk of a stop loss order not being executed for whatever reason, and what to do in that case.

I understand that order does not get filled AT ALL if:
-Client cancels the order
-The server is having tech/connection problems

Any other reasons an order can fail to execute?

Thanks a million.

That wont be a huge concern.. your stop will usually be filled.. the worst that will usually happen is if price goes darting through your stoploss level you may experience slippage and get filled for 5-10 pip more a loss than your stoploss was at.. but price would really need to blow through there.. slippage of a pip is more likely

your stoploss is going to be executed when price falls beyond it.. so it will get executed eventually like I said even if there is slippage

if somehow your stoploss never got executed I would contact broker and I bet they would credit your account for the mistake... if not I'd take them to court and find a new broker in the mean time


least of your concerns tho.. especially if you have a small account..
