I have a couple of algorithms running live. One has been running since mid-October, the other since mid-November. The Live view and dashboard for both has been getting progressively slower the longer they've been running. In fact, for the longer running one, the dashboard never ends up loading--it just gets stuck at the spinning "Downloading chart data..." point; the second is now taking 5+ minutes to load.

Given the pattern, I suspect this is due to attempting to load all data available for the algorithm since initial launch. As such, I think QC should switch to defaulting to showing 1 day of history. This will allow the screen to load faster, probably save QC some money with the hosting provider, and still allows users to later select however long of a period they'd like to see the data and chart for.
