I use Interactive brokers (IB).
I want confirm that when I build a 5 min chart and 15 min chart, does NT send separate requested for 5 min and 15 min data bars to IB or does it aggregate the internally stored 5 min data and build the 15 min chart ?
Can someone please clarify on the inner working of the data storage ?
If NT does data aggregation from the 5 min data to build the 15 chart, how can I prevent it from happening and force it to get the 15 min data bars from IB ?
