Problem merging historic data with real time

Postby hughesfleming » 13 Oct 2014

I am following the instructions but have a problem...

In the format instrument tab merge data sources is checked

I have historic EURUSD data from PI trading and realtime data from Lmax.

I have set ascii mapping for historic and I can bring in the data until 8/8/2014 which is correct. I have set realtime for the LMAX EUR/USD.

I end up with a chart with the historic data and real time updating correctly but missing all the data from 8/8 until now. Clicking reload all data does not help unfortunately.

How do I get the data from LMAX to start filling in the data from 8/8 ?

Many thanks,

Alex

Hello Alex,

That is expected behavior. Missing data between the last data point of historical symbol and current moment using realtime data will not be backfilled.
Real-time data will be plotted only from the moment you have created a chart.
That it is not possible to set a certain rollover point at which historical data will stop and realtime data will start.
In order to have a complete dataseries you need to import the missing data into the historical instrument.
