Im not even sure what I use that could be logically explained. Ive never used a chart. well I looked at RSI like a couple times when some skype buddies were swearing by it. Mine is prob just experience and intuition 70% of time. Rest is just basic OS, float, history of CEO etc.
Your stock trades are your own responsibility. No one forces you to make the trade. Always take responsibility for your own decisions and you will never have anyone else to blame
