Description:After a while, searching the MQL4 community looking for an explanation on how to calculate the highest and lowest values for a data series over "n" bars; I end up with this indicator that display exactly that. There are various post explaining how to use iHighest and iLowest, i acknowledge all of them. This is just an application of it that suited my needs. Feel free to use it and modify it. Image:

There is another indicator I think doing the same called i-HighLow //+------------------------------------------------------------------+

Choose for N2 "0" and you have the same. See http://codebase.mql4.com/1099 |
