general question about start profiling on real data

[faustf]

Hi guys  i see the start profiling on real data after  this  when i stop i have  some  bar green and  blue  , anyone  have  documentation about it  how  can interpret this  ?

i saw in metatrader editor the tab  profile  i open and  i saw  what is stressed i attach a foto but  iOpen is stress the platform, but   how  is possible reduce the impact ??  exist somthing  that give a  suggest , i ask this  because if  EA stay open  after 40 min the  metatrader  is  very slow  and  i must remove EA , and  restart metatrader  for return to normal situation i suppose Ontick is problem , i call my script only one  time at hours, anyone have suggest  thanks

i try to use OnTimer instead OnTick , but not  start never  but  i belive i use  a good syntax
