Concerning downloading tick data for 13000 symbols, there really are some
limitations, first of all limitations caused by time. Supposing you have a
broadband connection, the eSignal servers are not overloaded and running
smoothly, a single query to the server and its response takes about a
second. This means 3.5 hours on only queries for 13000 symbols - add to
this the time needed to download several gigabytes of data.
Besides, we've ran additional tests on GlobalServer itself, and although
the program itself is robust and fast enough, it does have serious
limitations on the volume of information stored and the ability to upload
huge volumes of history data.
By the way, a small announcement from me. Sometime around New Year the
second version of UniServer is due out. The program will include such
features as: Automatic search and filling of gaps, Incoming data filtering
capabilities and Downloading the data from a ASCII files directly direct into GlobalServer. Hope those additional
features will be useful to our customers. The new version of UniServer
will be sold along with the old one, but for a higher price. All users of
UniServer will get UniServer2 completely free, so anybody planning to buy the program,
consider doing it now.
