Keep on having Crashes

[fabrizio]

Hi Alex

Keeep on crashes....do not know why.

I'v downloaded the latest driver release for this machine video board (ATI RADEON 9000)driving two lcd screens . I keeep on having same problem you'v noticed of Mobs and Ellipses in Foreground rather than background. So , don't know whatta touch.....on the other machine where I'v got a Matrox Pharelia 128 driving three LCD screens, AGET is working 90% of times fine.

Two more questions:
A) how long backwards can I set the backtesting?
B) For what concern the overlay2 , I'v read your ansewers on the forum but do not know how to solve the ES problem . I'm exeperiencing the same of the other guy so once is on SPX fine, once on ES ..trouble.....

tks

Leaving video card issues aside for the moment here are the answers to your other two questions.

A) Depends on the interval.
- if tick based (ie Tick-bars, Constant Volume-bars or Seconds-bars) then 10 days
- if intraday then 60 days is the current maximum (this will be increased at some point and time)
- if daily or higher then 10+years

B) When you use an overlay (even with the second formula I suggested) you need to ensure two things
- use a Time Template that is set to #Days rather than #Bars so that both plots start on the first bar of a day
- you need to use a Time Template where the sessions are common to both symbols.
for example: if you are plotting $INDU and the overlay is ES #F then the Time Template needs to be 9:30-16:00 EST otherwise the extra trading hours of ES will cause it to unsync the plot from that of the main symbol. This may change at some point and time if and when eSignal introduces zero-vol periods, but AFAIK nothing has been decided on this issue yet.

With regards to the display issues you are having, IMHO these are often related to video drivers and/or hardware acceleration.
One thing you may want to try is to change the hardware acceleration in your machine. I don't have winXP so I would not know where to set that but in win2k you would right click your desktop select Properties then the Settings tab. At that point you would click the Advanced... button and go to Troubleshooting tab.
If the slider is set to Full acceleration try reducing it and see if that has any effect. FYI this will also have an effect on the speed at which the screen is redrawn.
Also make sure that the drivers you have for your card are indeed winXP specific. Although winXP and win2k are similar (many drivers are in fact interchangeable between the two OSs) they are very different when it comes to multiple monitors.
