What is the theory of supply and demand: understand and find the price zones that occur between buyers and sellers. The side that has more pressure will lean towards that side.
Draw price trends to know if the market is up or down => buy or sell.
Connect the peaks to determine the resistance zone
Connect the bottoms to create a support zone vùng
At these lines, it is difficult for the price to pass through the base, you can place from these lines to trade, but you have to set a stop loss so that if it breaks, you will lose less.
Trendline: Rising support points will form an uptrend and vice versa
Retest phase: investor’s hesitation phase.
