Global Server: filtering data

["Carl Vanhaesendonck" <carlvan@xxxxxxxxxxxxxxxxx>]

This is probably a basic request: I am using Metaserver to send Internet
data from a web page to Global Server. From times to times, there are of
course some "noise" in the data and...the quote of USDJPY is sent into the
column of EURUSD. Therefore I have to delete these bad rows by editing the
data into GlobalServer, which is very time consuming, and I am only watching
a dozen assets!!
Is there a way to filter it in order to avoid any price that is different to
more than x% than the previous one to be recorded ?

Thank you for your help

Carl
