Amit, It was a lot of perseverance but I never donned the 'specialist hat' ! The moment you wear it you start feeling the 'master' ! I have in the past and am at present and shall continue in future to be a 'slave' of the master, will dance to its tune always!
I primarily use 15 minutes TF to trade but I start my month with 5 minute TF and if I am able to accumulate some profit I switch to 15 min. TF ! The change from 5 to 15 usually happens almost from the second day of trade in the month !
Basic reason being my commitments other than the market. I am sure my actions would have been very different had I been trading for my basic expenses.
I dont advocate changing TF as per market conditions for a simple reason I dont know what are "various market conditions" ! My believe is that barring some really BIG BIG BIG news or event nothing in a 5 min. or 15 min. chart is going to change by the time my Target of 10 points is hit. And for that I have my SL in place ! And moreover
I am trading crude for few hours only, never the entire 14 hours its open for trade.
I suggest stick to your game plan! Let the market do it things and you do your thing. Market follows its own whims you follow your 'rules'!
A senior member did advise me not to trade near the time when Crude inventory figures are released !
