Open position, close position, stop loss relationship

After opening a position, we often struggle with when to close the position and when to stop the loss. In fact, I think it is the same thing, when to close the position? You just need to see if you don't have an order now, will you open a position at this time? If not, you can close the position, and stop loss is just closing the position at a loss, which is the same thing. Therefore, I have always opposed setting a fixed stop loss in advance, and even more against setting a fixed stop profit in advance.

The market is changing dynamically, but we want to use fixed stop loss and take profit! ​
