(sorry I had originally posted this in the wrong forum)... I opened a forex account with one of the "leading" dealers (perhaps to be mentioned at another time). I put in my first live order on their platform. It was a stop order to open a short position. I watched as the bid ticked several times below my stop price (just by one tick). I then cancelled the order, and the cancellation went through instantly. As it turned out, I would have been quite wrong had I successfully opened the trade. But my concern is, of course, what if I had been long, and the sell stop had been missed like that? I would appreciate any feedback. I have not traded Forex previously, other than on demos, so I don't know what to expect in the "real world". Would I have been filled at a lower price if the market continued down? Not filled at all? Could I contest the trade (or lack of trade) like I could with a stock that has time and sales?
