In every time frame (especially swing trading), every reasonable system works from time to time, then seems to go bad, and then is good again. The holy grail in trading is recognizing when your system is not working don't continue trading like "the Wall Street fool that thinks he must trade all the time" - Livermore.. A reasonable alternative is significantly reducing size. The emotional toll of fighting unfavorable conditions ends up putting you in so bad a place you cannot even recognize when things have improved once again. Yes a great trader can endure poor conditions but why? Reading market tone therefore is the Holy Grail which maybe can be taught but I think it simply takes the time to experience various market modes to learn them.
