Hi Mike, thanks.
I am talking about one symbol, just take the first signal that appears and remove all others.
Further i made a mistake in my previous postings, i said "Sell" but it should be "Short".
So for a recap: I want to take the first signal that appears (Buy or Short) and remove all other signals for that symbol for that day.
Right now i'm working with Exrem and got all excessive Buys and Shorts removed, but that still leaves me with 1 Buy and 1 Short signal a day.
How can i remove this last excessive Buy or Short signal?
Your idea should work, but i'm not a great coder so i hope there is a simpler way to do this.

If you get 3 Buys from 3 symbols on the same bar, which one do you take? Whatever logic you use to make that determination will bias your results. You would likely be best to select from the 3 at random.
