in trading we must know when to buy and sell because otherwise we will lose the moment to make a profit
Of course, buying and selling at the right time will determine success in trading. That's why a trade must have a good analysis of the time for entry and exit. You must understand that trading isn't for everyone, right? The reason is only a person who has a good understanding and knowledge about the market analysis can succeed in trading.
Besides that, following market developments is also important
All traders must know about this. Following the market development is a must because it may change the trends at any time. Failed to follow it, may cause we miss the moment to sell/buy.
