At this point i'm just trying to get my head around the loading of historical charts and whether the frustrating wait times i'm experiencing are normal or not.
If I load 30 days of ES ## ## expiring 1st Nov 2011, in 7 tick Renko format, with no indicators, it takes several minutes to load. This seems like a long time, but if it needs to download the historical tick data, thats fine. Which it apparently does - at 300kb/s for a few minutes.
However, i would then expect that the next time i load my session, the same chart should come up relatively quickly, having already downloaded the tick data. Which it doesn't - it goes through the same download process.
Why does my NT seem to keep needing to download the same historical data? Am i doing something wrong? Is data downloaded via a chart the same as manually using the 'Historical Data Manager'? I have tried downloading relevant chunks of tick data using the manager, and yet any charts i try to load within that period still take ages and still do their own lengthy download before displaying.
The problem gets exponentially worse if i try to load a larger period - 90 days for example. I have to load the chart 20+ minutes before i want to start looking at it, and every time it downloads a large amount of data - regardless of whether or not i've loaded that exact chart before.
Any help would be much appreciated!!!
Thanks, Damien
