On other point though Gildage... is it 'fair' (I know who says life is fair) that a mechanized trading system can program in 4 micro trades in the last minute of trading (oh and be the seller as well! They fleece themselves to manipulate the market) whereas a normal traditional trader could never accomplish this?? Not sure that is so in tune with the principals of a free and fair market place of equal opportunity.
Cheers
