Hello FF!
i made a tiny revision to a code to create this CCI Cross indicator for an FF friend.
the issue is, he also wants a num_bar parameter just like in the WoodiesCCI indicator (see below)
i still lack sufficient skills to incorporate that in the indicator.
all replies are appreciated.
btw, my personal question is, does the number of bars ( num_bar ) calculated always affect the CPU resources? (that is, does smaller input on num_bar always = less CPU resource usage?) or is there no effect at all?
Thank you very much!
