You just have to set it yourself, after a lot of back-testing. Of the many trading platforms I have, I like Trade-Ideas the best.
I cant really tell you what filter to use 'cause trading mentality for everybody is different. For example, I shorted BSDM at $3.3 when it showed up on my SHORT trading filter, but it rose to $3.4 after I shorted, and I shorted some more there, and then it rose to $3.5, I shorted more, and then it went to $3.6, guess what I did? Thats right, SHORTED more.
Everybody made fun of me 'cause they said I was 'wrong', but just 2 days later, BSDM was at low $2s, it may have even touched the 2.00 level i am not sure. Point is, thats my mentality.
If this goes higher, I will short the life out of it. wait till then end of the week, if not before
