Report max value over indicator data series

[Tdschulz]

I'm trying to create an indicator which calls for the max absolute value of another indicator over the past x amount of bars. For example, suppose I'm using CCI and want to get the max abs value over the past 500 bars. I want to get the highest CCI reading over the past 500 bars and the min CCI reading over the past 500 bars. Then take the ABS of the min reading and determine the max value of those two readings.
Where I am stuck is how to determine the max or min over the 500 bars of the indicator. Can someone give me some direction?
Thanks

Hello Tdschulz,

This is available with custom programming in NinjaScript. There are built in methods MAX() and MIN() that do this.
