Hello everyone!

I'm very excited to try Zorro, however I'm having some trouble to figure out how can I access previous values of the ZigZag indicator. For example if I want to get the rPeak value but 2 values before the current value, how would I approach it? I know rPeak is a global var type, but how can I access for example rPeak(2)?

Thanks so much in advance for anyone that could point me in the right direction!!
