Hello I did a search here and found a post by Tomasz that says this
"eSignal subsciptions have limits on number of simultaneous symbols and only that number can be really fed in real-time. AmiBroker can however scan larger universe provided that you are using Professional version and "wait for backfill" check box is checked in Auto-Analysis screen. Note however that once you exceed the eSignal limit, the program needs to switch active lists and perform backfilling and it slows down scanning process *a lot*. eSignal may also start to throttle your downloads (backfills) if they detect a lot of such activity." Now... I have an eSignal account with 200 symbol limit. I have an End Of Day database with about 225 stocks in it. When I run an exploration on that database... I get results from azpn to xmsr - that is, the results seem to come from the entire range of the 225 stocks in the database. However, when I click on the eSignal Data Manager and choose Data--> Symbols, I see a list with about 134 items. The very first stock is listed there, and then a postion of the list starting with the letter 'H' is there. This is weird. First, AB seems to have done the explration on stocks that are not in the list shown as being accessed by the Data Manager. Second, the Data Manager shows only 134 items. I might expect it to show 200 of my 225 items(running up agianst the symbol limit) but not 134. I tried checking the 'Wait for Backfill' box as suggested and here's what happened. I ran the Exploration agian and I got two more symbols than I did the first time (without checking the 'Wait for Backfill' box. However, the two extra results I got were on stocks that were actually in the list of 134 that showed in the Data Manager BEFORE I checked the 'Wait for Backfill' box. Does anyone know exactly what is happening when you are using eSignal's RT data feed to establish an EOD database and then running an exploration on that database, when the database contains more than 200 symbols?
