all you need is green and red box, when below -1 ans +1. Great job !!
So my coding skills pretty much end with what I provided. (I can mess around with code, but adding to it usually ends in disaster for me...lol.) However, if we look at the Fw_fishertransform indicator on tos, which is the final version of the code I provided, there are soap signals. Perhaps the "ready, aim, fire" signals come from the soap signals. Soap is "served on a platter" a david elliot term. I suggest looking at the final tos version as there are not too many parameters to mess around with.
Be happy to provide more insight.
