Hello. There is a problem which causes great annoyance to me - switching between periods sometime takes unexpectedly loooong time. For newly added instruments that simple operation may take 50+ seconds. See attached video for example - switching between periods for just added AAPL.US. This happens on LIVE account.
My environment is: 100mbit external internet connection in europe and 9600K CPU. These means roughly 10MB/s download speed at best (and it does work from some sites) and no reason for slowness caused by CPU in my workstation.
I checked local cache after operation completed - data for the period being displayed, files named BID_candles_min_1.bi5 for March - take 480k in total, this is roughly 0.05 sec at 10 MB/s.
However first occurrence of "BID_candles_min_1.bi5" appears at AAPLUSUSD\2020\08\03\ and total size of BID_candles_min_1.bi5 for AAPL is 6.6MB - I would expect download time for this volume in range of 1..10 seconds. Actual time to switch the period is 5 times longer than the worst time I expect for this operations. Waiting for such long is really annoying.
Another thing - I see no need to download 7 month of history at once while only 2 weeks are initially displayed.
Please improve performance of switching between periods.
