Quote from trade2live:
HFT traders have ruined the market. I read that it's now possible
to make round trip trades in fraction of seconds (e.g.1/10th).
We need some kind of level playing field , the other problem : HFT traders are sheeps, they all do pretty much the same thing. At least , since they are around, markets are no longer the same, have you noticed.
Regulators need to say enough is enough , and put a limit on how many orders can be placed and how many trades can be executed in a given time span by a trader. We could say we are alll going back to manual, that is trades have to be manually entered by the trader and this would not affect other systematic traders. But that'isn't possible, but something limiting inputs should be considered. The point is some rules have to be put in place, the loads placed on systems may also become a systematic risk at some point .
before they do all that they should stop sub penny orders
