This is such a cool feature. When I first tried to do this in python, it would take all night. Doing this with c and WFO is really a quantum leap forward for me.

Is there a script example of iterating through technical indicators and values? For example, EMA for the short signal, DEMA for the long signal, then the opposite, then TEMA as well. The idea being to optimize the best indicators and the best values for those. Does this make sense?

Iterating through indicators would probably not produce good results, but if you still want to do it, use an array of indicator function pointers and iterate through that array. It's not trivial. You will need wrappers for some indicators.
