I do not know how much accuracy you need for your studies'
- RM NF data is from 9.16 onwards
- what is yours data start time, 9.15 or 9.16
anyway, if timing is adjusted in amibroker, you wont see bars (of) beyond that time, say after 15.30
yes, IMO, that is a visual change, as bars beyond that timing, wont be there in charts, but in quote editor of amibroker, data will be there of all timings (as per feed)
if still there is a problem then you have to delete that data (those 2 bars data) manually, regardless it is of a day or a month or an year or more, no other alternative
BTW, if yo are trading Commodities and also keeping data/charting for Comm, then this wont work for you, as comm timings are beyond 15.30
