Hello,
In short you have to use Professional Edition and mark "Wait for backfill" checkbox in AA window.
("wait for backfill" is available in Pro edition only)
But I need to comment a bit on this: frankly speaking eSignal is not intended to be used as EOD data source for 8000 symbols.
They monitor subscriber activity and will lock your account if they notice that you are
switching 8000 symbols (on say 100-symbol account).
Even assuming that they will not lock account, downloading history for 8000 symbols would be very slow.
eSignal is designed to be used as real-time streaming platform that delivers tick-by-tick, intraday quotes for
few hundreds of symbols.
There are data sources specialized in EOD data such as QP2 and TC2000 that can update
EOD database of 10000+ symbols in a 10 minutes or less.
Best regards,
Tomasz Janeczko
