Hello
I’ve noticed that results output from debug lines does not appear on live testing, only on backtesting.
Have I got this right or is there something missing in my understanding?
Please let me know

Based on the information provided in the extracts, it seems that you are correct. Debugging lines are primarily used for backtesting. The debugging tool allows you to slow down the code execution, step through the program line-by-line, and inspect the variables to understand the internal state of the program during backtesting.
However, for live algorithms, you can use log statements to record string messages to a file for analysis. These records can assist in debugging logical flow errors in the project code.
Here is an example of how you can use log statements in Python:
For more information about debugging and logging, you can refer to the Debugging and Backtest Debugging sections in the QuantConnect documentation.
