Save analyzer Output to Log

cwse

Hi,

I am currently saving 'all' BT output to a logfile, however I am not sure how to save the last 'printout' from the analyzers. Is there someplace in the code I can opt to have the output written to a file?

Thank you!

@cwse Maybe look at providing an instruction in the stop() method (either in the strategy or analyzer; I'm not sure which, but my hunch is you'd look to the strategy) to log final output. I have not done this myself, so I'm speaking out of ignorance, but that would be what I'd try.

writer saves all data as .csv files.

The actual output produced by an analyzer is free. It is regularly a dict but must not be. It is whatever is returned by get_analysis and as such free format.

The Writer, which as pointed out by @ab_trader writes everything to a file, tries to take into account as much as possible to produce a sensible output, but this may not work with all possible return values of get_analysis
