Hi Josh
I had RTD 1.4 working on one machine with Nest Trader, Zero's earlier version (guess 3.11)
everything was running as is, for ages,
Last week upgraded the Nest Trader to their latest version, I guess it's 3.16, no changes in RTD 1.4 or any configs files etc.
Real time quotes working smoothly, 1 day back-fill thru VWAP also worked well, (tried only once)
For multi day back-fill, it was opening the data tables on Nest but not updating in AMI
Have not tried any further tinkering as did not have time to try stuff during live market hours,
also have not used your RTD 1.5, so no feedback on that
Maybe others can try out using RTD 1.4, with newer version of Zero Trader for live quotes and 1 day backfill, hope this helps
Thanks
Happy
