Hi everyone,
I'm working on the Creating a Rolling Window bootcamp. However, when I submit a backtest nothing comes up in the chart area. Then when I submit another backtest I get an error message of:
API Error Message: The account owner has reached the limit of available concurrent backtests (1 backtest)
Is there a way to view all running backtests? Maybe the backtest I submitted stalled and I need to manually stop it.
Thanks,
Chris

According to https://www.quantconnect.com/upgrade the free version, does not allow parallel backtesting. In order to cancel a currently running backtest to start another one, I usually have to close the backtest tab, rebuild the algorithm, then press the backtest button again.

Hi Jason,
The problem is I am unable to do what you are suggesting. If this were the normal algo lab that would work but for the Bootcamp it's a little different. I really think a Backtest is looping or stalled but I have no way to clear it.

Hi Jared and Jason,
This problem has been resolved. I was able to fix this issue via a suggestion from the chat room. I didn't realize it was possible to open the Bootcamp script in the "My Projects" section, but looking back I should have guessed this was possible. Opening the Bootcamp script in "My Projects" caused the buttons in the top right to come back in and I was able to stop the backtest. Maybe this is a bug in the bootcamp front end? Should these buttons in the top right be available in the Bootcamp screen?

Hi Chris, those buttons are intentionally not there to provide a simpler user interface for the training environment. Thank you for the feedback though we'll look into making the Boot Camp experience better.

I'm not able to run any tutorial in the bootcamp due to "the account owner has reached the limit of concurrent backtests 1 backtest" error. Tried to close everything but still give the same error...
