Is "Buy bid, sell ask" practical?

    I tried using this method in a trading simulator and made quite a lot of winning trades. :eek: But in the real world, is it possible?
  2. Depends how much is ahead!
  3. Sure it's possible with DAT. But the simulators all make it seem probable, and easily so. That is the difference. Simulators operate on the premise that if there is a bid or ask at a price, you get the fill. Real time isn't as nice.

    Buy bid works some if you work it;
    Like vega said , when it reverses.:cool:

    Never did mind helping a market maker or specialist by buying ask price ,sell bid !!!;
    works swing trading or position trading some ,buying bid.

    Intuitively, it seems to me one can NEVER really buy the bid. When you try to buy the current bid, you don't get filled until the market has moved down so that your bid has become the market's ask.

    Besides, if you think your success will be jeopardized by one tick on each side, you're fishin' in a dry hole anyways!

    What is DAT?

    I agree. But for a very short-term trader, the usual profits are a few ticks, this may cause some problems.


    At least 90% of my trades are bought at the bid and sold at the ask. Granted the trade may go against you a small amount if you get those fills but I try to play the probabilities of correlating the overall market movement with the individual stock movement.

    No, it isn't possible consistently to gain from this. Sure, you can often hit the bid, but when the stock moves against you the few cents you had hoped to make on the spread will look very small. A few of those moves...and you will have many...will wipe out any gains you may have made on trading the spread.

    I am assuming here that you are speaking of buying the bid and selling the ask as a quick in-out trade.
  10. it is possible with nyse. that is basically what enveloping is. search elite for threads on enveloping. if the specialist wants to make a print at the bid or less and you have an order in he has to fill you too.
