No connection problems

[MT4U]

On MT4 I am having a weird issue. 

On loading an self made indicator on two charts, everything works ok. The moment this indicator is put on a third chart, i am getting No Connection error restarting MT4. 

What could be the reasons for this?

1. Why did you post your MT4 question in the Root / MT5 General section instead of the MQL4 section, (bottom of the Root page?)
             General rules and best pratices of the Forum. - General - MQL5 programming forum
   Next time post in the correct place. The moderators will likely move this thread there soon.

2. Post the indicator. Do you really expect an answer? We can't see your broken code. There are no mind readers here and our crystal balls are cracked.
