Ignore yesterday's results - AFL

[aryan.]

Lets say I have a system which displays the names of the stock which satisfy the conditions.

Filter = C > Ref(C,-1) and ref(C,-1) > ref(C,-2)

This displays Stocks A, B, C

Tommoow I download new EOD data and run the scan again, this time the following stocks are returned D,B,E

Can I program the afl to somehow remove stock B because it was displayed in yesterdays result and I dont want it in today's results.

How should I do this in afl.

Try this

Filter = Cross(C,Ref(C,-1)) AND Cross(Ref(C,-1), Ref(C,-2));

Try this

Filter = Cross(C,Ref(C,-1)) AND Cross(Ref(C,-1), Ref(C,-2));

Excellent logic.
