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. This produces a huge load on the total chart refresh rate, making subsequent operations such as scanning, switching symbols and so on, slower. I was thinking that if I could separate all this stuff into another instance (separate database with ONLY required symbols, much shorter history such as 10 days instead of 10 years!), then I can get this realtime display and have my main AB running like a song.
I have tried it this US market morning and THE PROBLEM I am encountering, however is not AB! IQFeed client is crashing on me when i try this configuration. Apparently it doesn't like it. I am not sure whether to continue the tests or find another route. cheers, eToke --- In [email protected], "sidhartha70" <sidharth...@...> wrote: > > eToke, > > What exactly is the advantage of running two instances as opposed to having > more chart windows under the one instance...? > > The only advantage I can see is that if you are running multiple cores it > splits the processing load more effectively...?? > > > > --- In [email protected], "etoketrader" <etoke@> wrote: > > > > I normally run one instance of AB which displays my "main" section - charts > > on the instrument I am working on at the moment, as well as a "market > > internals" section which shows charts of the major indices, tick, trin > > etc.... > > > > I am trying a small experiment in order to see whether things run smoother. > > I am trying to run 2 instances of AB for the two sections I mention above. > > I am not sure whether this will make things better but currently the fact > > that I am simultaneously charting several symbols at once is putting > > additional load on my setup. > > > > My question: Some symbols exist in both instances.
