Need help understanding bandwidth for data stream
I live in a remote area with a slow but mostly stable DSL line, so I need to be careful of my bandwidth. I'm running one monitor machine that has a lot of charts open and a Market Analyzer. With multiple monitors, I use this machine to visually see when the charts are moving fast, and also have indicators on the Market Analyzer to give me alerts for my trading conditions.
On the second machine, the ones where the trades are placed, I have 3-4 charts open, but also have a Market Scanner running because that is the only way (or so I understand) to guarantee that when I flip between instruments on a chart, that the historical data will be correct. When there is action on a specific instrument on the monitor machine I will change one of the charts on the trading computer to that instrument. Because the Market Analyzer caches the data that data is already on my machine (the way I understand it) and it is loaded immediately from the cache.
The result of these two Market Analyzers on two machines on one DSL connection is that I may have up to 20 data streams at one time, one for each instrument in the two Market Analyzers.
I am monitoring the bandwidth with NetLimiter on both machines and noticed that Ninjatrader on the trading machine is taking at times 2-3x the bandwidth of the monitor machine.
Can some explain why this is so I can make adjustments to preserve bandwidth?
