Maverick,
Sorry for my ignorance. I went over your posts about double prints and tried to see if I could identify it.
How can you tell double prints by looking at the quote window. The quote window just gives you the last price, bid and size. I cannot tell there are two prints with the same size by looking at the quote window.
One more question.
Do you use charts? I don't think there are rooms for 15 charts.
Just the quote window and yes, you need a good eye. Hopefully you have customizable columns that allow you to use colors that are easy to see. I would watch every print very carefully and when there is a double print, it would flash twice. If you think you missed it, you can always briefly put up a time and sales window and double check, but a good tape reader doesn't need to do this. You just need to really pay attention.
No, I never used charts. Not only were they a waste of space, but they distract you. If you are staring at charts, there is no way in hell you can be catching those double prints on the tape, trust me. Besides, all the info you need about the stock is on the tape. Looking at squiggly lines is not going to tell you if there are two or three buyers in the stock, where they are buying and when they get taken out. It simply is a useless distraction.
I did always keep a sp 500 futures quote up though and watched it like a hawk. Very very important to know what the futures are doing.
