By the way I tried calling Status("redrawaction") and it returned 0 every time in the trace window, over and over, which means the action is not a timer action.
That however doesn't mean it's not a timer action from an external plugin, just that it isn't a timer action from the AFL timer function. So that proves nothing probably.
As of now it really seems like your theory is true, but if so how come nobody ever noticed this? Is everyone importing static data? People who are using live feeds, have you never noticed your functions are being called over and over intra-second?

There's no way this window or whatever backfilling its doing (which it can't possibly be doing if the network is unplugged) should have any impact on how often an AFL gets invoked in a chart window. But I thought I'd mention it here to see if means anything.

If you have entered more than 1 ticker since the time AB session started and are in realtime mode, AB will try to get those quotes as well as for the displayed ticker (running an AA session or have tickers in an open realtime quote window also counts I believe). The number of tickers AB will try to get I think depends on your data provider - 200 sounds to be plausable.
