Need a coder to fix some bugs on my indicator

Hi dear coders,

with my limited knowledge i created an indicator that works fine most of the time, however sometimes there are problems like :

- the arrows paint all over the screen

- sometimes mt4 does not connect to the server if the terminal was closed having any charts that had the indicator loaded

- the indicator  sometimes gets very very slow, and sometimes mt4 freezes.

I need someone to optimize the code and / or to fix these problems.

Source code will be handed after private discussion.

My budget is fixed !

Thank you
