maximum net profit for a variable range

Question

I am trying to display maximum strategy.netprofit for a range of a variable (l1). It is not displaying maximum value of the strategy netprofit but is changing with max value of l1 (l1MaxIn). Is there a simpler way to achieve this? Thank you, George

I` want to display max value of netprofit for a strategy when a variable varies in a domain (l1). Instead, the expected max value changes with l1 max value, that is l1MaxIn. Is there a simpler way to achieve this (i.e. for loops, etc). Thank you, George
