There are many methods but primarily what suits my personality type.
My trader friend 'Santanu' ,he works on Cash Mkt only earning 1k to 2k daily ,consistently.
He never looks at EoD or 1 min or any charts prior to mkt opening.
After opening he will compare the Nifty chart of Yahoo with nifty stocks in PIB.
Select the ones in sync with Nifty movements & get those at top of his watch list & look at Tick charts Only of those selected .
Then he will find the Support / Resistance points (his proprietory method,though time & again he has explained that to me but as it is a bit subjective & cant be coded but only determined by observation i have never tried that) from EoD .After this he will place Alerts in those price points in PIB & move to next one.
When the Alerts come he will just look at Tick charts to observe how the scrip is reacting at that price point & take a position.Whenever the movement goes in his favour he will place a SL covering only the brokerage & simply forget that scrip for the time being & move to next one.Like this when 2 to 3 positions taken & SL placed,he will simply close every thing.
Periodically he will open his computer & increase his SL of those positions surviving,until 3.20.
At 3.25 he will sq up all his positions & after 3.30 simply switch off mentally from mkt until next day 9.55am.
He is one of the most Simple guy earning consistently since 4 yrs & never subscribe to any Forum or meet traders except few close old day trader friends.
