OooooooooooooooooooooooK ……….You place a pending order on any platform and every man and his dog working for that brokers trading floor sees it sitting their ie: common knowledge…..
and believe it or not a stop loss is a pending order, simple.
What they do with that info is up for debate but it is not illegal for a broker to hedge against it or do a thousand other things to off set it.
"Arbitrage" would be a good place to start if you want to learn a bit about the mechanics of the why’s and wherefores
