Quote from TM_Direct:
Ok Q. the reason it's illegal is that it creates a false market...for instance: You are sitting there trading and you have Volume break outs as one of your parameters....and a stock called ABCD pops up on your filter and says it's now traded 100,000 shares today , when in fact it's 4 week daily volume average is 15,000 shares a day.....you might be more inclined to buy it right?
Ok, So im a Market Making firms with 200,000 shares of ABCD in my inventory a price of 5.oo per share....i sell 50,000 shares and the guy sitting on the other side buys it form me....daily volume is now 100,000.....and here comes QDZ with his 1000 share order , most likely above market, because hi filter says this is a volume breakout and somebody must know something.....clearer now?
