Hello,
I have just installed 5.3.  The streaming charts is having difficulties on my machine.  If I stream 1 minute bars using any symbol like "GE" using Fidelity datasource, every minute when a new bar closes, the chart flashes to black, hangs for about 5 seconds and repaints with the new data.  During this time all the other charts are frozen to.  At one point I got a un-handled exception on something like LockedBars function.  
I have tried re-booting, but this has not fixed the problem.  A streaming chart without a strategy works fine.  A streaming chart with an indicator works fine.  But if I install any of the standard strategies it hangs every minute.

        Let's get a Support Ticket for this.  Clearly there's something up on your machine that we're not seeing.
