eToke, I use something approaching your setup, but under one instance of AB. I have 8 charts across 2 monitors. 5 different layout which allow me to switch very quickly depending on exactly what I want to look at.
My AB runs like a song... I wish I could utilize more of the 8 cores I have on my PC, but it does run quickly. The single biggest factor in processing speed is the number of bars in your DB. In my intraday DB which I use for day trading I have 25,000 bars max. How many bars do you have in your DB...? --- In [email protected], "etoketrader" <et...@...> wrote: > > I was thinking the advantages would be the following: > 1) The split of processing load as you mention > 2) In order to run market internals, I need to display several charts for > several instruments at once: > - Tick > - AD Line (this needs a few instruments actually to build correctly) > - Interest Rates (that's 5 yr 10yr and 20yr > - SPY/QQQQ/IWM > - Market Sectors (XLU,XLP,XLE etc..) > ...and so on.
