The volume/tic data loading is a real issue. Data loads when you click an instrument, if you zoom in to the chart after the data has loaded, the data starts loading again. As a software engineer myself - I don't get how this can be an issue, what am I missing?
- My thoughts would be that a local database (in memory perhaps) would store the incoming data if space was available in local storage, otherwise continual downloads would be required ;/.
- Time stamp downloaded data in intervals so that the last clean data point would be known and faster retrieval for smaller timeframes.
- As new data is available, diff against time stamp and retrieve only required data.
I'm scared to touch my mouse. I selected GDX today and it took 20 mins to download (I have 2Gbps dedicated), but I know if I click something else and come back to the said symbol - it's going to take a load of time to reload - crazy!
For now I continue to envy my friends who chose and invested in other platforms ;/
