Quote from kotika:
Strange...
I see crossed bid/ask on the big SP sometimes, that is ask is lower than bid. Whats this mean? Is it because this is pit market and quotes dont mean much, as was hinted by some people on a previous thread? Or is this stale quotes my broker is serving up?
The 25 point spread on the mini is too much, imo. In theory, If you could make market in an instrument which has too large a tick, buying on the bid and selling at the ask you should be able to consistently make money, that is if the market is fair. Any opinions?
If i had some intraday data, i could run some statistical tests to see if this idea is right. Now that still wouldnt mean you can make profit, probably you had to have very sophisticated automated black box to enter the orders, basically to make sure you are near the top of the order book when the price comes near.
