Be clear that this behaviour is illegal. Totally. This is the heinous crime of not being Goldman Sachs or RBS or $BIG_FOFF_BANK with political connections. Make offers that others slavishly follow because they haven't got a clue what the real value is, you're getting prosecute - even if you will trade at the prices you quote. Manipulate libor, bullshit credit risk, rip off your customers with buy recommendations while selling? Help the greek govt get a loan that immediately doubles? No worries. Only small guys who cut the big guys lunch have anything to worry about from regulation enforcement. This is called "regulatory capture" and it's just appalling how common it is and how little is done about it. Hell if you're even seen as a big player you can literally rape children and get a deal for a ridiculously light sentence and they agree to stop investigating and prosecuting other offences and then be met by a member of the royal family when you get out. Literally rape children. http://www.theguardian.com/uk-news/2015/jan/03/lawyers-seek-evidence-prince-andrew-lobbying-jeffrey-epstein http://www.theguardian.com/uk-news/2015/jan/03/lawyers-seek-... Is there nothing all these lawyers can't corrupt? Yeah the things they fucked up through sheer incompetence. Anyway kids the lesson here will be HFT is bad for you because the spreads in the market you can trade are now tighter, so you have lower transaction costs putting more money in your pocket but Goldman's lucrative market-making is lost to them. Bad for goldman's is bad for you. Oh and bubble markets are caused by short-selling. Investment fund reporting season, rash of stories about HFT and short selling and how evil they are - just please ignore those huge fees mutual funds charge for their underperformance. 1-2% of your wealth per year. 6 figures of your money, please look at short selling and HFT and not that because that's not scary at all.
