You don't provide any info what you are using. Built-in plugins run fast. You are probably using slow WINDOWS technology called OLE and import via OLE. Or you have a badly coded 3rd party real-time plugin. Or you use some weird setting in "Number of bars to load" .... Or you run a computer from 18th century. Or you use crappy slow AFL codes not being optimally coded and not being appropriate for realtime. No one knows since you offer only one sentence.
this is what i have...
Windows 7
Intel core i3
RAM 2 gb
system type 32- bit
Realtime data software: IBC
AFL: NO... no afl or indicator.. only price
Bars to load: 1000(dont think thats too much as using it with ami 5.1)
thanks
