Flash Trading - Friend or Foe
Though much of the negative press regarding flash trading has mostly blown over, it is likely that most people never really understood the issue in the first place. And if you first heard about flash trading from a main stream news outlet, or Jon Stewart, you probably have the wrong idea. While easily 'spun' into an ugly wall street monster, it is actually completely legitimate. Check out Kid Dynamite's explanation:
"Now, the intent of flash orders is to allow participants in a given market center the opportunity to improve the current bid or offer so that an order doesn't need to be routed away to another market center.
An example: let's say GE is trading $11.45-$11.50 at DirectEdge, but that there is an $11.46 bid on ISLD (an ECN). If you submit an order to sell stock at $11.46 on DirectEdge, they flash this order to select market participants to offer them the opportunity to fill your order - otherwise the order gets routed out to ISLD and you (the seller) have to pay an extra fraction of a penny for the routing. As I tried to explain on some other posts regarding flash trading, this is basically a hyper-speed modernized version of how the NYSE specialists used to verbally quote orders to offer people in the crowd the opportunity for price improvement: "if GE was 11.25-11.27 50k up, and you walked in to sell 50,000 shares, the specialist would say out loud “25c bid 50,000, 50,000 at 26c, SOLD.” Anyone could say "TAKE or BUY'EM" before the specialist said "SOLD" which would result in the seller getting price improvement to $11.26 and if no one interrupted him, the trade was done at $11.25. Markets have NEVER been setup such that every participant has the same opportunity to trade on every quote."
