Usually one trades for the following 3 reasons:
Generate Income - Intra Day Trading
Generate capital - Swing Trading
Generate wealth - Positional Trading
Strange as it may sound, believe me to succeed in any of these trading styles one should have an alternate source which already meets the reason for trading that style. For example if one wants to generate income through day trading he should already have a day job making him enough income, similarly for generating capital and wealth. Only then one will have the disciple and stress free mindset to succeed. There are exceptions but usually very rare.
I strongly believe the goal of trading should be to generate wealth, one cannot build wealth if the focus is only to generate income or capital.
This is my personal opinion, the best way to succeed is to follow this process:
1. Initially Trade intraday only to build a Price Action based trading strategy (Mechanical/systematic) and not for generating income as it will be quick way to find your edge.
2. If the intraday strategy (Price Action) has an edge it will definitely work for swing & positional as the only difference is the time frame.
3. Always measure the Effort/Time spent to the rewards received, if your alternative income source or day job returns are better continue with it and trade on the sideline passively to generate the required capital/wealth at a faster rate.
4. Once the returns from trading is more than that from the alternative income source for a considerable time period (1-2 yrs) one can shift full time to trading that style.
5. Always focus on the end goal which should be to generate wealth as quickly as possible before retirement, one cannot continue with pressure and stress related to day trading all your life. Once enough wealth is generated one can easily trade intraday/swing with confidence & disciple as it will be more of keeping oneself occupied and be in touch with market.
