I read "Market Wizards 1/2" ages ago, unless there is something I missed, just mostly generalizations than much of anything else, but what it will keep repeating is have a Trading Plan.
The elusive "Edge" most talk about thinking have to have one, I never heard of this till last few years actually, LOL. It certainly isn't trading method, more like confidence that been built with education of the markets traded, and years of study of human emotion and catalog that. I think writing down your emotion when first learning how to trade, watching the market and write down what you want to do trading Price Action, cause the 95% are trading this way. By better understanding yourself, you will learn what others "feel" as well and why. People get out of trades cause of fear usually. The Pro's take other side of emotional trades, often times creating the fear, LOL.
So many will say systems fail, but the developer failed at adapting rules when Price increases/decreases volatility, that's like saying Price Action stopped working and yet if you look at charts from 100 years ago on Wheat, you be surprised how they look like todays' with exception of cents per bushel. I think it is more of not having rules in place to adapt to changes in action.
Options are no different than any other market, if you don't know the rules of the game, you will lose. But I think with options, once you understand how to trade them, they offer much easier way of making money without watching them so often like day trading. You can either learn the Math side, learn price action side of the underlying or both.
"How to make money in options", take a good book on charting price action and trendlines, when price comes down to support in an uptrend=Put Credit Spreads are safe play, when price goes to resistance in downtrend=Call Credit Spread, when price shows triple extremes, Head and Shoulders, trade accordingly. If price breaks trendline by so much, get out of the long option and keep short, perhaps this short will cover the loss in long option. I believe what too many do is keep it "hoping" it will come back, which it seldom does.
