Hi Dennis
My problem re delayed quotes remain - it probably is related to the
plugin. When I select shutdown and then reconnect by Rclicking the
connection status button, the prices immediately come up to the
second, but gradually fall behind again. Notice, it remains green
(till on select shutdown). It does however have a blink (<0.1
seconds-my estimate) most of the time.
The plugin connects as a TCPclient (listed as most efficient) and I
do have the option of trying to connect as a UDPclient, HTTPstream,
or HTTPrefresh. Does anyone have experience with these connection
modes? Any advice?
Also, is there anyway via afl to 'flash or ping' the plugin to keep
it awake? Does GetRTData or GetRTDataForeign make a request of the
plugin or just get data from within AB?
Can't help you but re your last post, did the prices keep updating
though the charts stop updating (I don't think the HLC+vol need your
afl to be running, and T&S,RTQ wouldn't need the afl to run, would
they)?
