Weird Backtest List Behavior Today

Hey Marc! 

Thanks for the report. We released a new feature updating the backtesting list to follow file system hierarchy based on the backtest names.  Your backtest names probably had a path separator character ( `/` ) in the name therefore you see the names followed by the folder icon. 

To go back a level you can use the navigation at the top of the backtest list (`Backtests>Folder`)

We currently show the folders first therefore your new backtest seems to be getting pushed down to page 6 I believe 

Thank you

Noticed the same thing. It's nice to be able to have folders now! (although I had dates like “1/15” so those are all in folders now! whoops)

However, I also noticed a change in plotting. It always used to plot in the order I called the plotting method. 

So if I called: 

self.Plot("Pricing", “midPrice”, “self.mid_price”)
self.Plot("Pricing", “highPrice”, “self.high_price”)
self.Plot("Pricing", “lowPrice”, “self.low_price”)

They would always render in that order and be consistent, with consistent colors to evaluate easily. 

Now however they are not in order and I'm not sure what the order is, it appears to be random. Any ideas?
 

This is even happening on old backtests that have already been run (the order of the plots have since changed)

Ronit;

Where is the heads up for this change? I don't see anything in the announcements, or Lean, or Community Feed. Using search, I am unable to find relevant documentation about this feature.

I now have ~100 backtests that have been moved into individual folders. They are out-of-order and out-of-context with their related historical backtests.

Even if I manually rename the backtests, how do I move them out of their folder? 

Common abbreviations (likely to be used in QC): 

• n/a (not available/applicable), 
• w/o (without)

I used the latter extensively in documenting and distinguishing my backtests while testing new features. Now it's a mess.

IMHO, this is a breaking change, and should be reverted (and folders removed), to be re-applied once the backtests' “/” are auto-renamed to something neutral (“|”, “!”, “?”, “+”, “~”, “ ”).

Sorry for the hassle Marc. We don't notify the community about every bug or feature we ship. We also did automatically rename projects to neutral names when we applied the folder feature to projects, and it also annoyed many people…

We'll attach a notebook here shortly, which will do a mass renaming for you. Then alone who wants can run the notebook cells and it'll just “fix” your account.

Hi Marc Daoust 
Sorry for any inconvenience caused. Enclosed is a straightforward script leveraging the QC API to update backtest names by replacing "/" with "-". This will help maintain clarity and organization, avoiding any potential confusion and fix this.

You can run this in your research env and it will fix all the backtests in the account.

# To run the fix for all projects and backtests in your account
# get all project list
projects = api.ListProjects().Projects
for project in projects:
    project_id = project.ProjectId
    # get all backtest for the project
    backtests = api.ListBacktests(project_id).Backtests
    print(f"Project Name: '{project.Name}'  |  Project ID: {project_id}")
    for backtest in backtests:
        backtest_id = backtest.BacktestId
        original_name = backtest.Name
        updated_name = backtest.Name.replace("/", "-")
        api.UpdateBacktest(project_id, backtest_id, updated_name)
        print(f"Updated backtest name from '{original_name}' to '{updated_name}'")

# For one specific project
project_id = <add project id from weblink>
backtests = api.ListBacktests(project_id).Backtests
for backtest in backtests:
    backtest_id = backtest.BacktestId
    original_name = backtest.Name
    updated_name = backtest.Name.replace("/", "-")
    api.UpdateBacktest(project_id, backtest_id, updated_name)
    print(f"Updated backtest name from '{original_name}' to '{updated_name}'")

Script test:
1) Error with backtest

2) Running the script

3) Backtest Fixed

Let me know if you have any issues with this. I have attached a backtest with the research env having the script.

Best,
Ashutosh

Thank you Ashutosh, I ran it with the ID of the main project I'm working on, and the Backtest list looks good. 

All the backtests are in proper order, with a dash replacing the previous slashes, and the folders have disappeared.

Marc.
