What does adaptability entails? Adaptability teaches you and lets you know when to switch from "sell at resistance" to "buying the breakouts of resistance" within split seconds. Know this and be at an advantage especially during price correction that occurs during bull run of prices.
In term of theory is right, "sell at resistance" and "buy at supportance" but not be easy to determine what resistance and what supportance is important, not wherever price will also react when reach "resistance" and "supportance". So in my point, adaptability will come when we have experience enough long with market.
