Having never done this before, evidently, the second script I published was too close to the first one and I got a message from the mods. So, I am trying to make it right but just making the new one the standard. It can still work the same way as the old one, just use the same settings and look back for both sources/trend lines.
With that out of the way, the new version is meant to add confluences by using two different sources, with signals only printing when both trend lines are in the same state. I recommend using the 8 and 21-period smoothed moving averages. If just want both sets of signals, you can turn off confluence mode as well.
