How to manage funds well?
1. Always set a stop loss after opening a position; you must develop this habit. Always set a stop loss when opening a position, and never harbor any delusions.
2. The stop loss amount for each trial position should not exceed 2% of the total amount (depending on your own risk tolerance; I suggest starting at 1%, and after you can maintain stable profits, you can adjust it based on your own risk).
3. Strictly enforce stop losses; if total funds lose 30%, close all positions and exit immediately without conditions.
4. If you forget to set a stop loss and realize it later, you must close the position immediately. Never expect a rebound to close the position or think about adding to the position to average down the loss; almost all big players fail in this aspect. You might survive 10 times, but if you can't survive just once, all 9 previous times will amount to nothing.
5. For initial learning, it is not recommended to add to positions; just open a fixed position each time.
