If there is no bear market, who would be willing to do swing trading? Bands are simply not a way to make money! It's just a survival rule forced to derive from market changes.
Just like being a mistress, who would want to be a mistress? Wasn't it just because he couldn't get it that he was forced to take this step?
So don't be fooled.
Swing trading does not exist in the market itself! Have you ever seen Buffett preach the band theory?
You have only one opponent who firmly holds the currency: betting that the cycle will come.
