As for me, the best way to learn is to work on a demo account.
Whatever you do, don't longer on demo trading for too long before starting on the real life trading. Trade fills and feels aren't the same as they're on demo and live platforms. You may not notice this if you don't look intently. Demo is good for practice but I've come to realize that it isn't the ultimate. It's better to acquire the set skills for trading first and then start live trading with small capital. One shouldn't rush it. Just take it in bits and increase one's confident level, is my way of looking at it. Left on demo alone, one could demo trade for years and still become a loser once one goes live.
Go for the easy and simple way, just buy when the market is hitting red for a while then sit back and relax the drama this will be an exciting for rich people because they don't invest the money they needed for survival so follow the strategy and surely anyone can be rich in long term.
A lot of traders tend to call it the oversold level, even though there may not be a thing as such in reality. It's just that the market operates on the psychology of traders. Once market dips for that long a lot of traders and investors take it as a cue that a reversal is imminent and then buy in. It's a nice entry strategy, if you asked me.
