Dear Experts,

I have a question regarding 2 version of QQE indicator. First and foremost thank you Mladen, MrTools, mntiwana
The above two indicators are:
TOP: QQE (thv adaptive).mq4
BOTTOM: QQE (vhf adaptive) 1_6

how are these indicators used?
1) Are trend signals / Entry given when QQE line crosses the WP lines?
1A) if we are optimizing we can just stick to one WP line and just test different value?
2) Should QQE ever be used as a 0 cross for signal / entry? (ignoring WP line crosses)
