Hello,
I have a question about opening up the backtest result.
Say I am running a backtest which would take several hours.
If I close the browser window where I triggered the backtest, and open quantconnect website again, I can see backtest server is still in use.
I believe the backtest that I've triggered is still running, but if i open up the backtest result from the result tab to see the result being updated, the graph and all backtest result has just stopped updating and stays where it was when i close the window.
I can't tell if backtest is actually running because my backtest takes several hours and just waiting is time-consuming.
1. In such case, will backtest result will show when the backtest is finished?
2. Is there any way to have it update result intermittently?
Thanks.

It looks like the cause is that I pull too much data using history.
However, it suddenly happens after 2 hours backtest and undeterminisitc, so it is really hard to debug.
Any advice on this (supposedly) memory leak issue on the backtest server side due to too much data request using History?

Instead of running history requests, you can pull the next slice of OHLC data, for example, in the OnData part of your algorithm, saving you a history request call.
For an explicit example of how to do this:
