It is said that when you bid your shares, someone can jump in front of you; looking at the order book.. how can I know that that happened? I wish to cut that bid in order to eliminate the risk of not being filled. Tx
If you're talking about equities, there are various ways for certain big/powerful players to do this, depending on what country you're talking about. In the US, this can be done through "broker/dealer internalization", which is explained here: http://www.zerohedge.com/article/in...-broken-market-nanex-conclusively-proves-hfts, amongst other places. In Canada, a broker (probably working with an HFT) can do this through a loophole called "broker prefrencing" or "broker priority", which IEX is trying to bring to the US, unfortunately.
Tx men. Now i understand what are they doing more or less, i saw that behaviour before lol, i though my order book didnt worked property. Tx you very much,.
