For stocks, I only use one trading strategy! It's based on a "pullback". To my mind, learning this single trading strategy could make a profound impact on your trading profitability over time. Watch this video to learn the strategy:
That trading strategy has a lot of "raw edge" in back tests. What I mean by that is that I tested it with different entries and exits, and as long as the pullback was based on an uptrend that had a strong, sustained upward price movement, then the back test I did showed profitable results over time.
That said, I choose to only trade the really big stocks. Why? It's because in back tests, they performed slightly better. Again, this edge applied to all stocks I tested in back tests (although I didn't test this against penny stocks or OTC stocks), but there was a distinct enough difference among bigger stocks that I choose to limit myself just to those.
This stock trading strategy uses a couple of indicators: Keltner Channels and ATR. That page will give you more information about them so that you can understand them and configure them in your trading platform.
Some of the pullback trades of stocks end up overlapping the companies' earnings announcements and ex-dividend dates. That page talks about my approach to those trades and what back tests show about those trades.
I take a very methodical, rules-based approach to trading stocks. I follow the back-tested trading strategy as explained above. But there are times where discretion might come in handy, if not for me then for you. On that page I talk about types of ways where discretion could potentially be valuable.
This pullback trading strategy is one that, according to back tests, may have a lot of raw edge. This is a good thing because it increases the likelihood that this is indeed a bonafide edge and also because it allows us to have flexibility when we want or need it with our entries and exits.
