Tomasz,
I can add a little more information to this problem now.
This morning about 11:45 ET my chart stopped again.
I was trading ES and the market was fairly fast.
I have a Bar%Done graph that advances every second.
It takes the start time of the last bar and compares it to Now.
It stopped advancing.
I clicked to another chart tab and back again.
That made it advance one time, but would not continue running.
Clicking on the refresh chart made it go again.
So I think that my AFL formula stopped running.
I will verify that by other means the next time.
Best regards,
Dennis
