Hi,
I think this issue is across the board. I am also getting similar
crash when I use the indicator MFI(14) on the same data.
How other users are coping with these issues with a real time feed?
I have found two measure issues with AB real time use:
1. If data feed received has a few quotations out of synch with the
time stamp the chart crashes. This is normal practise wit hany data
feed like IB or QT whcih I have tried and I would think other data
feeds also have the same issue except esignal, I suppose.
2. Explorer does not give correct result on RT data. For a day for a
symbol explorer can only pull few quotations even if there are many
quotations for the same day in case of RT data.
Regards
Choco
