......Brokers are also traders, and as such they know your stops....if they know enough stops it's worth their while to 'trawl' them.

The banks and brokers that trade, can XT trade and you don't know who the other is because it doesn't come up in the buy/sell order. So in all probability it's possibly them making a quick buck from a quick trawl. Then back to the game.

They DO KNOW your stop level. I don't think there is a law at present which requires them to 'hide' your stop setting from their internal system. Although you may think your smart not setting a stop on a nice round number, they don't care, they accumulate a range of set stops until it makes it worth their while to drop the price and 'trawl'. Then they bounce the price and you buy back in, in a rush to 'win' back your loss.

Ethically a broker should not be allowed to trader.
