For those who are interested in trading, I would share some of my intraday trading routine:
1. I scan the market for potential gappers - stocks that have released earnings, stocks getting upgrades or downgrades, or have news that may potentially move it and those that attract high premarket volume
2. I look for stocks that are at least $15 and has average volume of 1m per day. These are stocks that will attract institutional play and you always want to have momentum behind moves for intraday scalps
3. Decide a bias for the day... look at futures, potential economic release, premarket then trade my shortlist in the direction of both the index bias and specific direction that the stock may trade due to the news, earnings etc Always follow the direction of the main index... it typically leads the indiv stock that one trades by some 5 to 10 mins.
4. Sometimes, it gets tricky - gaps may fade or may runaway - and one may not be able to spot the retracement - that's where technicals come in.... I always trade only if there is a technical formation - be it trendline or horizontal support or resistance, looking for breaks or support or resistance to hold.
Once you are comfortable, this can be quite routine.... on a fast day, I can wrap up trading within the hour... on a slow day, it may take 3 hours. This is often harder than swing trade but it can be more fun and exciting (provided the market moves in your direction)
