Sapna,
Every one is in search of the "Holy Grail ".Which actually is not there in full perfection , moreover it varies from individual's time frame & objective.As i am an absolute Intraday / Exteremely short term Swing trader (based on EOD data ) hence many Osc/ Indicator may be very good but does not suit my trading style.Plz determine your trading style ,Risk/Reward ( sustaining capacity both for Profit/Loss ) etc, then search for Indicators / Osc .Actually these indicators / Osc , which have worked on past data & gives you an edge against the odds,always use atleast one confirmatory signal other than your main signal & the trend must start in the higher time frame (than the time frame you use ) , before initiating a trade.Cheers.
