Hi,
For backtest, I can use 'lean report --backtest-data-source-file FILE' to get the beautiful graph backtest report.
I tried similar for paper testing with command 'lean report --live-data-source-file FILE', but it always fail with below information (which seems for backtest only)
Error: Missing option '--backtest-data-source-file'.
What is the good way to get paper trading performance and portfolio change? When I begin paper trading like 'lean live paper-test-2 live-paper', it will keep running until I ctrl-C to quit. Then from where (there seem multiple json files under live folders while only one main.jsaon under backtest folder) I can measure the algorithm is good or not.
Same question for live trading.
Thanks,
henry

Hi Henry,
The LEAN Report Creator can also generate reports of live results, but only alongside backtest results. If you want to use it to plot live results, you need to use both the --backtest-data-source-file and the --live-data-source-file options, the former pointing to a JSON file containing backtest results and the latter pointing to one containing live results. The live file that you need is the one ending in "_minute.json".
