Leland, QCharts requires very little bandwidth. In general, it takes some bandwidth the first time you start QCharts and a little extra when you open a new symbol. For instance, I have two copies of QCharts running at the same time on two separate monitors (legal if both run on one system). The right monitor is my market status monitor with: - 3 1-minute barchart of indexes - 1 quote screen with about 15 futures and indexes symbols - 1 quote screen with about 12 indicators (tick, trin, etc) The left monitor is my analysis monitor with: - 5 bar charts (1 , 5, 60 minute, daily charts) - 3 quote windows where I track about 12 symbols per window - 2 Level II window - 1 Island window - 1 Time and sales window - 1 tick window - 1 news window - 1 Single quote window - 1 Trade Rate Hot List window Each of my bar charts have multiple indicators including: - 10, 20, 50, 100 and 200 (daily only) period EMA's - Bollinger Bands - Volume - ADX - Stochastic (daily only) When I load QCharts it downloads about 24Kb of data at about 4-6 Kb per second. When I enter a new symbol, it causes all windows to refresh (unless I lock a symbol on the Level II and one extra bar chart window). This takes about 5Kb at about 4-6 Kb per second. After that, the normal price/volume and hot list updates take about 200-300 bytes per second! In addition, I have CyberX, E-mail, one or two browser windows and my QFeed-based scanning software running. My scanning software tracks 450-500 symbols in real-time using the same data feed (QFeed) that QCharts uses. Bottom line, it is VERY efficient bandwidth-wise. I rarely run out of bandwidth. It does take some horsepower, however. I have a dual-CPU, 400Mhz system with 500MB of memory. My two copies of QCharts and my scanning software alone take 80-100 Mb of memory. One instance of QCharts with my configuration takes about 20Mb of memory. Regards, Dan.

Leland, I have run them both simultaneously (along with Interquote) on one AMD K6 300 notebook. However, I don't use a standard modem connection but rather a LAN with a webramp internet server using three 56K connections at once. I have used Real Tick 3 and Interquote together on the same notebook (vacation) with a standard dial-up connection. Worked fine. I'm sure Q-Charts will work even better, as it's design is very efficient in terms of band width usage. Something about a proprietary packet compression thing...? Uses much less bandwidth than RT3, FWIW. Matt
