VertexFX Currency Server Help
Posted by Mohammad Rahhal on 11 October 2012 10:21 AM

VertexFX Currency Server Application is one of the applications that has to be run at server side, so the Gateway Application ( the main application on the server ) gets the prices of the symbols from it and then these prices will be reflected to Backoffice and Clients platforms.

Currency Server takes the prices of the symbols (Spots, Futures) from the data feed application (must provide a DDE links) which is installed on the same local host server (For sure it's recommended to be in separate server to not affect in the system performance), or it can take the prices from another Vertex Currency Server.

If your feed is not DDE supported, and gives prices from API, in this case you have to develop your own currency server using this API to take prices from and VertexFX Currency Server API to send prices to your VertexFX system.


When you run VertexFX Currency Server it would look like the following picture:

You can notice that this application have many columns

Column Name  Description

Bid Lists the bid prices for all the added symbols in the currency server
Ask Lists the ask prices for all the added symbols in the currency server
High Lists the highest price for each symbol added in the currency server
Low Lists the highest price for each symbol added in the currency server
Bank Displays the bank name according to which prices of the feed are filtered
Volume Shows the dealing side of each symbol added in the currency server
Filter  The value that is used as a standard of comparison and all level prices should be in the range of the filtering value; if a price came from the feed that exceeded this value, then a filtering will take place
