The short-term trend is reflected in the direction of more than a few days in the hourly chart and the 4-hour K-line chart.
The medium-term trend is more than a few months, which is reflected in the daily K-line chart and weekly K-line chart.
The long-term trend is reflected in the direction of more than a few years in the weekly K-line chart and monthly K-line chart.
After distinguishing short-term, medium-term and long-term trends, we can distinguish the price direction of each time period. If the price gradually inclines upward and the price is higher and higher, it is a bullish trend. On the contrary, if the price hits a historical low, it is a short-term trend.
For example:
Prices in the short-term trend are getting higher and higher, which means that the short-term trend is bullish.
Prices are getting lower and lower in the long-term trend, which means that the long-term trend is a short-term trend.
Combined with the long-term and short-term trends, it is concluded that the long-term trend is short-term decline and short-term price is bullish. In operation, the trading strategy is short-term buying and long-term bearish.
