The best trading strategy(ies) is within yourself. Don't look for some magical source elsewhere. There's some truth to this -- it's not just philosophical mumbo jumbo.
And the best teacher/trainer to follow is the live market, rather than any mentors or historical data! However sometimes lessons can be very dear!
Investing with long term trends ( long trends measured in "years" ( in the U.S. markets) have statistically high persistence ). If you want to attain "alpha" vs. the S&P500, invest in stock universes that have been proven to produce highest decile alpha premium via empirical research over decades. These universes include: small cap value, mid cap growth, shareholder yield. These can be attained through low expense equity based products ( ETFs). A simple, low transaction, and empirically tested way to reduce risk and compound assets has been to use a price vs. 10 period monthly moving average of the S&P500 crossover strategy ( investing in equities when price > MA and money market when < MA ). Further alpha can be produced when a long dated bond fund is implemented ( when S&P500 price < MA ( money market ) and bond proxy > MA, then invest in bonds, if not then cash ). Decent risk adjusted alpha has been produced with the use of the "mid cap growth" Powershares Nasdaq 100 ETF ( QQQ ) as the proxy for equities within this strategy over a 30 year period ( 14.2% CAGR 1986 - 2015, 13.7% CAGR since 2002 - 2015, 15.5% 2008 - 2015. Of course, past performance is no guarantee....
http://adamhgrimes.com/TAAS/about-the-course/ That has given me a good foundation to work of. Covers many topics. Is suggest to actually work at it, don't skip to just the patterns. His book was also great. His podcast has some good material "market life" and his blogs pretty active with stuff to get you thinking. I stumbled upon it from listening to chatwithtraders.com. Great interview s. Has lead me to some great resources and things to think about. Some of the guest will resonate with a style your approaching. Adam's style was kind of what I was approaching, swing trading off of daily/ weekly charts. I work full time and the time frame and style fits myself, not for everyone. Some of the traders from that podcast also have some pretty good webinars on YouTube and such. It's a process but I find I can take a bit and learn from the abundant information from some great traders. Just always be skeptical and prove ideas yourself whether it's paper trading( most the time doesn't provide realistic results), manual backtesting or a backtesting program.
In keeping the approach simple, it really comes down to 2 things. 1 What drives price up or down 2 The timing of entry and exits In #1 a trader needs to know what will move their market up or down, In #2 a trader needs to be able to see a pattern forming in real time, taking an entry based on this is possible and has a 50/50 chance but will not be high probability. That's why waiting for a price driver in the form of news / announcement with your emerging pattern can aid in your trade becoming high probability. 3 A trader waits for these items to present / align and takes aim to execute, this is usually the hardest for most because we all want to trade but without alignment we run the risk of shooting and missing the target analogy. Patience to wait is a rare quality in this game. What I've described is very black and white but unfortunately in this game there is more gray than both thus making the possibility error great ! Once again patience can help to keep those errors from occurring.
Trading just 1 title is useles and very risky. A good trading strategy has to use diversification, ie. portfolio or basket trading with at least 4 different titles, which should not be that much correlated to each other, ie. they should be diversified. Everything else is just gambling w/o any risk management.
