I am looking for a indicator or any other way to show me the daily candle retracement.
 
Based on my broker data, I want to know how every single candle (on a period of time) retrace.
For instance last Wednesday 16th EURUS NOV candle Open= 1.0721 Close=1.0690 High= 1.0759 Low= 1.0666
Then, this candle retrace to nearly 50% of the previous candle.
 The data that I need is the retracement percentage of every bar/candle (from 0-100 or 1000 if is more than 100% ). Most importantly, I want to be able to get historic data with those values.  Those values probably will be better if they are show as excel sheet.
