Hi Tomasz,
yes, i know that and have checked both (time setting and after hours
disabling ) before i have posted this snapshot.
Also the esignal support has confirmed my quotes, as displayed in the
snapshot.
What i have displayed in this snapshot is that the quotes are very
often not correct and that users should know this.
OK, probably it is the problem of realtime vendors.
