Mostly worked on "oscillators" that are good for swings but lousy for trends.
Tried to modify them to cope with trends. That class works much the same way, just variations on the basic theme. High, low, close and time are about what you get to play with, maybe volume, but people have been able to extract a surprising amount of variations. You can sort of "lever" the data from different directions to get you closer to whatever direction you are trying to go.
Programmers like inputs that are "bounded", stay within known limits like 0-1, +1 to -1. You know the computer isn't going to crash or have accuracy problems with safe numbers like those. Some signals are friendly to process and others are pigs.
Some have a signal that looks like CCI output but the "zero" mid line doesn't stay on one place, it keeps moving up and down and it melts my brain because it alters all the historical perspective when it does that. So you look at the old stuff, hey that looks like its got something to say, but when you try to trade off the leading edge you find it tells you nothing at all about the future, its useless, it only confirms what you just found out the hard way with no help from the indicator. argh
ADX main output is "safe" 0-100%, usually 20-70%, user friendly, easy to feed it into a VMA or whatever second stage. I gotta wonder if the dude who put ADX and VMA together was a major genius who thought it through before hand or a plug'n'play bit of good luck.
Any indicator in the same "class" as ADX might be tried with our VMA.
An indicator from another class might need some adaption to match its output to the input type that our VMA uses. Our VMA likes 0 to +1, 0 to +100%, like that. Other types that go +1 to -1 need to have the negative part sorted out in some way. Some signals like to hug the middle, some hug top or bottom, you get to figure things out as you need to do them.
One option with CCI that goes plus and minus might be to feed it through an ADX which turns it into just positive. Another way might be to just add 1 to it so it goes from +2 to zero. Depends on what matters, you can lever it different ways.
Fast is important, gotta be fast, lag is blown opportunities, one more pip margin on top of all the others.
Gotta stack good things in your favour and minimize as many bad things as you can. If its a laggy indicator, best to keep looking for a faster version in the same sort of class.
Its difficult to imagine anything being much better at giving "flat" than what we have got but who knows what some lateral thinking might flash up.
I would like a have a measure of a target exit price before entering, your icon is one flag on one bigger trade. The fantail spread/compress is a vague measure, it would be nice to get that as a hard number like 10 pips, 50 pips etc. If you have reason to believe the profit will be higher, you can tolerate risk or drawdown in the early stages. Trading with the trend can be useful in forex for the longer trades, if you have good reason to trust the trend, you can set your tactics accordingly. Hard numbers can be tested to see how reliable they really are. How wide is that fantail, well it depends on how zoomed in or out your chart is, as to how it looks, but is looks good enough?
If you rely on a trend slope, would a hard number on that slope tell you something about future payout?
Like you say Walter, 12 years looking for ADXVMA, needle in a haystack.
Then you go and share it....
