Of course! Market cycle it very important for me as a trader, Market cycle is like a cheat in the game, we can do research and analysis with it. Its very eassy to get a signal and find a trading opportunities if you already capable to read the market cycle.
There is no doubt that market cycles exists the problem is that you have no way to know we are in a particular cycle until several months have passed and we discover the cycle has changed but by the time that happens you have already lost the best opportunities to profit from the change of a cycle to the next, just to give you an example during 2018 it was way more profitable to short the markets than to buy and hope the market will go up, but you had no way to know that before the whole year passed so you needed to take the opportunities that appeared in both sides of the market.
