I experience very slow loading of chart data. I'm using IQFeed and the data load for intraday charts takes about 2 minutes (for 3 days of history) and daily charts about 1 minute (365 days).
Why does it take so long? Sierra Chart or Amibroker can download the same data in a few seconds with the same IQFeed API.
And finally - is it possible to use caching for the data? For example when I switch from a symbol to another and then switch back, NT always loads the data again and I have to wait another minute or so, which is inconvenient.
Thanks for your answer.
