Missing equity curve and weekly returns

[pigslayer12]

Hello, first thanks for sharing your work, its very useful!

I am having trouble with the pdf report, its blank for the equity curve and weekly return graph. The problem is I am not getting any errors so I dont know where to begin troubleshooting. Although I have tried a different pdf viewer without luck.

Also I used the post on "Actuarial Data Science" as reference and I have my code setup in a similar way. The difference is that I am passing an empty strategy and providing an external trade list using backtraders add_order_history. oh and I am using windows 10, and have double checked the requirements are satisfied.

The png images are generating correctly in the templates folder, but they dont seem to be getting placed into the pdf. Is this just an issue with weasyprint and windows? Thats my only guess. I followed the instructions to ensure weasyprint works with windows.

So, where should I look first to solve this problem? Thank you in advance.

edit: I also wanted to mention my datetime's are set to be the index column in my dataframe, and type() returns "pandas._libs.tslib.Timestamp", so I believe I have my dates set up correctly.

Thanks for creating the reporting tool. Same issue here.

Yes, I able to run the example successfully in Windows 7 with one warning.

Please advise. Thank you.

Great work! Same problems the charts are missing... Thanks!

Hi, Were you able to run the example successfully?

Yes, but the charts are missing. They are in the templates directory. But impossible to display them in the pdf report

[borismikanikrezai]

Ok - found the solution. The issue now is that my equity_curve looks weird. I will investigate.

I think this is because your code is working only for hourly strategies, not daily or weekly.
