How long do the short-term, medium-term and long-term foreign exchange mean respectively?

It depends on your own habits. For example, if you have a small amount of funds, your distinction is that 1 hour is short-term, half-day is mid-line, and 1-2 days is long-term. If you have large funds, 1 day can be short-term, 3 days can be medium-term, and 1 week can be long-term. It depends on your own trading habits. Short line, middle line and long line are all relative. For example, my distinction is that the profit of about 20 points is short-term, the profit of 50-80 is the middle line, and the profit of 120- 150 is long-term. Of course, some people make a short-term profit of 5 points, a mid-line profit of 20 points and a long-term profit of 30-50 points. It all depends on your own situation.
