How can I submit a group of backtests and have them service.write_.. to the same file? When I tried it with passing the same filename, the only data in the file is from the last job to finish running.
Backtests run with multiple threads, so writing to the same file on multiple days will result in errors. You can create an output file for each trading day (name the files by date). Or you can select " run as single multiday job" in the backtest dialog box and write to the same file, but it will be slower.

you can also create a file that has the trade date in the name and generate multiple files.
