In trading, capital management is crucial. There is no fixed answer for the choice between 'light position' and 'heavy position'; it really depends on individual circumstances.
Ability
If your entry skills are strong and you can accurately grasp the market's explosive points, a heavy position can amplify profits. If your entry skills are weaker, a light position will be safer, avoiding frequent stop-losses.
Desire
When desire is strong, you can adopt a heavier position to seize opportunities; when desire is low, a light position will make you more comfortable, avoiding excessive risk.
Risk Tolerance
If you can accept a larger capital drawdown, you can appropriately increase your position; conversely, if your tolerance is weaker, a light position will be more prudent.
Summary: Whether it's a light position or a heavy position, it should be decided based on personal ability, desire, and risk tolerance. The strategy that suits you best is the best one.
