FRUITFELLAS CANDLE PERCENTAGE

Hello Fruitfella!
 I have a question and I need your help. I've occupied the FRUITFELLAS CANDLE PERCENTAGE and it works great. 

I would like to know if there is a way not only to be able to analyze the last candle but also to be able to analyze the penultimate candle. I hope you can advise me on this question. Thank you, greetings
