To the best of my knowledge, if COBC = false in the parent, but the children are COBC = true, it will cause major problems. Best is to eliminate COBC statements entirely and control it on the panel, unless the indicator cannot function but one way in which case you have to force the issue --- which is best done in OnBarUpdate and not #init since it could otherwise be overridden.
I have already removed the link to the Median, you can now use the close. I have also checked into the differences between the pole 3 indicators. I think that fluxsmith's indicator has a bug in line 29:
I have researched this figure and found the following:
The formula printed in the book "Cybernetic Analysis for Stocks and Futures" uses the value 1.738 (have that book in my shelf). But a technical paper by John Ehlers on the bandpass indicator, …
Another update to jhlWMA. I suspect this may be the last, it's hard to imagine how it could be made more efficient. While preparing a refresh of jhlHMA for posting (pending), I had a thought on how I could calculate a WMA with less multiplication (an expensive floating point operation). This is pushing optimization further than needed, but a Hull moving average uses three WMAs, so inefficiencies do add up.
I just stood on his shoulders and converted it to my style. This version uses much less memory, is simpler for me to follow, and has a startup phase where it has a pretty good estimate instead of no value set.
It can be constructed from my generic MA adaptor (jhlMA) with only a period specified, providing a default phase value of 0.
