I agree, I tracked Nifty n Dow futs live charts for month. From 20 trading days of month, nifty followed dow futs tick by tick on 14 days approx. But its not true that one can trade nifty intraday accurately watching nifty charts alone. many times ( at least 50% times if not more) there will be buy signal on nifty, u buy, then suddenly dow futs change direction, ur sl hit. After few mints u get short signal, then again reverse happens. Only due to this reason I stopped trading nifty intraday n index stocks. If u will analyse deeply u will see that only index stocks follow Dow Futs or world mkts during mkt hours hence Nifty. Non index stocks dont seem to care abt Nifty n world. So u can trade them without worrying abt Dow futs. They can remain in red, while nifty would be up 2%. Or they will b flat or Up when nifty in deep red.
