Hi Bikashji...
This has been my personal observation... I am sure most of the traders would have experienced this as well....
Most of the big moves... start around these round figure timings.... Open up your Nifty 5min TF Chart and watch the timings of the beginning of sharp and big moves.... You would see that most of them begin at sharp 1pm, 1.30pm, 2pm, 2.30pm etc.... Being aware of this do help while taking trading decisions... almost always....
