I worked for a high tech company - the company stock was in a big channel channel, it was instinctive to buy at support & dump at resistance - repeating over & over - figure out you could time the market. Ventured into a few more high tech stocks when the first on-line broker opened - did real good. My friend that worked as a trader for Morgan Stanley turned me on to an entry level TA book in the mid 90's, I was all in. I did venture into day trading full time for 6 years, ironically with $ made from swing trading and investing only to lose most of it. Switched back to swing trading some 15 years ago - I will never drift again! Swing trading meaning holding positions up to months.
