> I normally keep up to 10 charts (different symbols) in 1min,10 tick,0.1 & 0.3 range bar,some in voulme bar,some in P&F (0.005x10) like that.
> My lap top not that strong. (only 2 gb ram/dual core 4 years old)
> 60 days intra day chart in too many charts in high volume/high tick symbols like SPY,XLE etc will freeze.
Setup here:
2004' laptop, 1500 Mhz Pentium-M, 1 GB of RAM, Windows XP Professional SP3, 60 GB drive, driving additional external LCD, using QT with 60-day patch, having approx. 20 simultaneous intra-day charts open, plus raw data and Level 2 window.
QT runs smoothly on this setup, memory usage stays well below 100 MB. I don't think I would be able to do this ith any other trading/charting software that is out there.
Hoping QT will be there for long time to come - I seen few other trading/charting platforms and nothing comes close in terms of usability, quote data presentational accuracy, abilities and features, agility, efficiency and lightness on computational resources. It's just showing great software engineering craftsmanship and devotion of its maker.
I wish somebody (JM?) would be able to devote his time and resources and work on issuing unofficial patches every now and then to keep QT working with TDAmeritrade/ThinkTech servers/data feeds, and/or other providers. Or; to share knowledge, know-how, code and insights on ways to do it. It shouldn't be that hard to adapt it to speak TDA (or other's) protocol after all.
