Foreign exchange transactions can be divided into medium-and long-term transactions and short-term transactions from the trading cycle. There are not only differences in the length of time between these two transactions, but also some other differences from the perspective of foreign exchange transactions.

The selection of periodic K-charts generally lasts for half a month, a month or even longer, while the period of short-term trading is generally within a week or a day, so the selection of K-charts is different. Long-term trading generally refers to the monthly K line or even the annual K line, while short-term trading generally refers to the daily K line, 60-minute line, 30-minute line or 5-minute line, especially intraday trading.

Generally speaking, short-term trading is to choose the right trading opportunity in the short-term fluctuating market, which is risky, so traders need to concentrate and arrange a certain time to make the market, while long-term trading does not need to make the market at all times, so the time schedule is not so tight.

Trading varieties choose short-term trading because they want to get considerable income in the short term, so the products have the characteristics of drastic changes, while the products with medium and long-term barter belong to products with relatively large investment potential, and there is no obvious change in the short term.

In the analysis method, short-term trading is carried out in a short time, and the general fundamental information has not been reflected in the market during the trading time. So technical analysis tools are often used in fundamental analysis, regardless of fundamental analysis. This is also different from long-term trading, which usually considers the influence of fundamentals.
