As a stock trader one must aim to make profitable trades as nothing beats the success as success begets success.
Make sure that when you are making winning trades in market time and again than stick ti that system. Their is no requirement for any change. This system can be any like trading on news based on acquisitions or dividend announcements or you execute breakouts or MACD crossovers etc..
If a system works for you keep going back to it until it doesn't. One of the best years I ever had was shorting recent IPOs after the insider shares unlocked. This worked like a dream until it became too popular and IPOs started staggering their unlock dates. Another process which has yielded profits for us every day are sure tip of the day and it works for us and it will work for you too.
