Share New Research 
I am really upset by this. Just yesterday I upgraded from the free tier to Research tier at $60 per month. At 9:30 this morning - after just half an hour of activity - I am stopped by this error.
I understand the need to cap disk space usage to a reasonable level in proportion to the amount paid. But aren't the logs from a backtest deleted when I close the backtest? If not, is there a way to delete my backtest logs so I can continue working?
Of course I can update to a Team and pay a lot more money, but I'm not a Team, I'm just one person, and I have no intention of putting a significant workload or disk space usage on QC's servers.
Is this really the way it is? If so, is there some alternative way to “log” my results so I can trouble-shoot my algorithm?

Follow-up question: if I use LEAN CLI to move my development and testing to an on-premises system, will lit solve this problem - will I have unlimited logging?

I too run into this issue once-in-a-while. The real problem is that there are no indication of your account usage of the daily allocation. If you run backtests that produce an unexpected large number of log output, and forget to check it before running more backtests, you get surprised by this lock.
Having a warning, or a count-down of your daily allocation visible on the IDE would be very useful.
I upgrade to Teams for that reason, but I still run into the issue from time-to-time. At that point I revert to self.Debug() to have a least some output to examine from within the Console window.

I am doing this same - using self.Debug(). Of course it has its own limitations.
I don't understand why the daily log limit is so low. If I used 100KB per day for 10 years it would amount to 365MB but by then I would have paid $7200 in monthly fees. That ought to pay for many TB of disk space.

Hi Marc,
We updated the Log Quotas docs to explain how to check the amount of log storage you have remaining.
Best,
