Hello everyone!
I've had this issue for many times but I haven't really asked for help until now. Attached is a short backtest that I made to replicate the issue (bug). If you backtest the code, you'll notice that even though the algorithm runs for 12 days, it only logged the self.Debug messages 1 time, instead of 12 times as expected.
My question is, is this a bug? Or is there something in self.Debug that I don't know about that is causing it to log only once.

Oh nevermind, I went through the docs and found out that identical messages will be filtered out, which is causing the algorithm to only run to log only once instead of throughout the period of the backtest.
I should have gone through the documentation first, my apologies.
