A one-sided decline is never considered a difficult market. If it were one-sided, wouldn't everyone just short it? So, what is a "repayment market"? It's one that constantly gives you hope to go long, while continuously triggering your stop-loss or trapping you. When you finally decide to turn around and stop going long to go short, then a big wave of increase happens. Once you chase the rise, oh no, there's another wave of decline waiting for you. The market keeps switching between different levels, without any rules or reasons. When most people have been stopped out and have lost their enthusiasm, and another large portion of people are trapped, with most of those trapped eventually cutting their losses, only then does the difficult market approach its end. It is still impossible to confirm the size of this adjustment level because different levels are inherently nested within each other. Even with a pre-set script, the main funds still have to ride the donkey while reading the script. They follow the market's reactions and choose the most cost-effective way to operate.
