Write to a file from indicator

[Leope]

Hello,
I have a custom indicator that write to an output file - Myout.txt. I followed the guidelines as in the documentation.
I use this custom indicator in market analyzer.
I get an error "Error on calling 'Onbarupdate' method on bar 72: the process cannot access the file Myout.txt because it is used by another process".
Since the file is not opened in another editor , could the problem be due to market analyzer calling various instruments that are trying to update the file ?


Any suggestions on how I can get this to work ?
basically, what I want is when an instrument called by market analyzer , reaches a certain position I will be able to record it in a Log file.
Thanks,
Lior

Hello Leope,

Yes, that is very likely the case that the analyzer being used is causing the problem due to more instruments trying to write at once. If instrument A is writing data while instrument B tried to also write data, it could not.

Does the output need to specifically be in one file? If not, a simple solution would likely be to make individual files so only one instrument can access the file at once.


I look forward to being of further assistance.

Hello Jesse,
Thanks for your answer. I will separate it a few files.
One thing I am not clear is - doesn't the market analyzer "call" the instruments from the list in a serial manner (one after the other) ?
If so , how can this kind of situation occur ?
Thanks,
Lior

Hello Leope,

In the Market Analyzer, because this tool is driven by market data each indicator would be called once a new tick is received for the instrument it is applied to. If you are using CalculateOnBarClose = true then they would still be called once each series closes a bar which would all be independent of each other.

I look forward to being of further assistance.
