Markets never go in a straight line, in either direction. One question then that a trader has to ask is at what level to expect a retracement, aka a pullback. Failing to account for retracement can either result in missing out on profits, by exiting the trade too soon.
Hidden support and resistance is virtually unknown to a majority of traders. Yet this phenomenon is responsible for many of the big trends and corrections that we see play out in markets over the longer time periods.
Let's face it. Buy and hold (hodling) is not for everyone. If you want to ratchet up those profits, or even create a bit of income from your crypto assets you need to look for something a bit more dynamic.
