The currencycyborg advanced indicator is a modified version of the gartley/zup indi.
This was used as a study model for research!
You can still ask them for a free working version.
Now here i have the demo version of there GRAIL indicator.
Use it only on 15min charts and yes it can be backtested. (don’t like backtesting..)
I have uploaded the indicator and sound files..
There is also an auto installer for less paranoid people.
Test and see..
I use it on the 15min charts and ony trade the buy and sell signals! do not trade the possible trend change!
