Been using QT for a couple of years and recently decided to explore swing trading (I normally day trade). This meant opening quite a few more charts. But when I get up to ten running QT begins to studder and freeze. The feed continues OK, but working with the charts (moving them, drawing, scrolling, etc.) becomes a lesson in patience. Every few seconds the program freezes for a fraction of a second. It can also be noticed in the moving bar indicator beneath the feed connect button - it stops and starts in coordination with the freezes. The problem is definitely connected to the feed, as when I turn the feed off all functionality returns to the charts - but of course no updated data. Here's what I have tried: Discussed this with Jerry Updated QT Tried two older versions of QT Switched on and off every option in QT Switched between IQ Feed and IB feed Upgraded and downgraded Java Fresh install of Windows OS Turned off all optional Startup programs Tried it without ButtonTrader or IB WorkStation running Tried bashing my head against the wall - that just damaged the wall Anyone have additional suggestions? Anyone else have this problem? Anyone had this problem and found the solution?
