It's easy to say, but once the market turns unfavorable, your positions get trapped, and then that phrase 'Come back later' becomes a final goodbye. You might think the problem is luck, but in reality, it's long been hidden in the details.

Many traders are unwilling to face a harsh reality: rebates and transaction fees are not trivial matters. When you're making money, they are just icing on the cake; when you're losing money, they can determine whether you have a chance to bounce back. But most people haven't even calculated their costs.

The transaction fee for market orders is calculated at one-thousandth (0.1%), which doesn't sound like much. The problem is, once you leverage and trade hundreds or thousands of times frequently, you'll be shocked to find—your principal has already been eaten up by fees. Only after losing do you regret, only able to say 'I should have known.' This is the harsh reality of the battlefield: everyone seems to be armed to the teeth, while you are using the most broken weapons, relying on luck.

The rules of the game are laid out plainly; everything operates within the framework. The key is to first prepare your basic weapons—understand your fee structure clearly—only then can you talk about strategies. This isn't some advanced skill; it's the most fundamental cost awareness.
