Hi Dm,
Below are answers to your questions. This will not be necessary should you switch to TradeStation 9.x and use Gelium's QuoteRoom or Forexite QuoteRoom. Dataset are different. I do not know how long more will Forexite continue to broadcast data.
1. What will happen to the history already loaded into GS (for 25+ years), will Omega still build charts on its basis in the same way as it did before renaming JPY A0-FX to USDJPY? Or for Omega to work normally after renaming the symbols, will it be necessary to load the history in ASCII text format for the same 25+ years?
Renaming the symbols will not affect the 25+ years data already in Global Server. They still exist as before. Only symbol change. TradeStation chart will still load the same data from Global Server as normal.
2. As far as I understand, the data that Forexite continues to broadcast and on which the QuoteRoom - GlobalServer - ProSuite bundle started working again, is still in the XPO format? Maybe I don't understand something, but if XPO is still broadcast, is it possible to somehow download them directly, for example using the same QR?
Forexite realtime data are transmitted in their own format, not XPO. Upon received at the computer, 2 things happen:
a) QuoteRoom convert the realtime data and directly update to Global Server continuously. No XPO is broadcast.
b) If History Database is enabled, QuoteRoom will also update to a database that TradeStation 9.x can read.
Gelium also host another version of QuoteRoom that get data from his data server and update to the TradeStation 9.x compliant database like (b) above.
3. The option that would suit me best today seems to be using QuoteRoom - GlobalServer - ProSuite - without making any changes, since now everything works the same way as before, + downloading files in ASCII format from the Forexite website, converting them to XPO and uploading them to GS. I would like to understand how possible this is?
If you only need
Daily data and now there is a gap from 21 Jun, you
can import from ASCII text file to Global Server for the missing days. You can keep the same symbol names.
QR and GS running everyday 24x7 non stop to update. If you stop there will be a gaps and the daily high low will not be complete.
For intraday data (1min and/or 5min) you are out of luck. This will start updating from now. Converting from text files to XPO requires XPO convertion software.
