Made this version that dynamically displays whatever you place in these two variables - no need to make a new version for changing the number of plots in mq4:
input string TraderPeriods = "3,5,7,10,12,15"; // Comma Separated traders List "3,5,7,10,12,15"
input string InvestorPeriods = "30,35,40,45,50,60"; // Comma Separated investors List "30,35,40,45,50,60"
