Herman, I'm still thinking about this one ... it would be nice to know the cause before trying to work around it.
I did two tests today: - 600 symbols (S&P500 plus a few) ... 3000 * 1 min bars == 6 days == 93kb per bar ... downloaded all OK .... eS DataManager popped up a warning at approx 30/60/90% of download == every 200 symbols ... I clicked OK and the download sailed on .... it would have kept going even if I hadn't acknowledged the popup. - 500 symbols (S&P) ... 100,000 * 1 min bars == 208 days == 3125KB per bar == way over the max possible bakfill (approx 6 months for 1 min bars) ... download locked up after only 4% == approx 20 symbols ... this is way below the cumulative byte for 200 symbols * backfill limit .... no warning about exceeding symbol limit. I am not sure about what the cause is ... eS fault, AB plugin fault OR throttling by eS OR something else. brian_z --- In [email protected], "brian_z111" <brian_z...@...> wrote: > > I use eS - I am not a heavy user or particularly knowledgeable. > > I have also had this occur. > > I concluded it was because I was exceeding my symbol limit....
