Avoid alert when chart is updating

[Deleted]  

Hi everyone,

I would like to know if there is a way or if one of you has an idea on how to solve my issue.

I have an indicator which produce an alert when some criteras are met. Everything is working fine but when I closed my plateform and open it again later, the indicator is producing an alert at the same time the chart is updating as if it was real ticks.

How can I avoid this? Is there a function to delay the indicator as long as the chart is not updated? 

 Thanks a lot.

You could try testing for error 4066

ERR_HISTORY_WILL_UPDATED4066Requested history data in updating state.

  1. Fix the indicator. It should not generate an alert except on the first of bar 0 or 1
  2. Indicators can not wait.

Thanks for your replies. I tried to test it for the error 4066 at the beginning of the start function but the same problem happened. I Tried to delay the execution by saving TimeCurrent() into a variable during the initialization and testing the variable against TimeCurrent() + 5 at the beginning of the start function but it doesn't seem to work either.

 This is the code for the indicator. The indicator is showing an arrow, playing a sound and popping up an alert everytime we have a serie of "iBars" bearish or bullish candles

 Thanks for your help.
