Is it really worth turning on the rebate? Let's do the math. When the market is good and your position is profitable, the rebate becomes your extra profit—equivalent to getting a portion of the gains for free. If the market is volatile and your position breaks even, then the rebate becomes your only source of income. In simple terms, it prevents you from losing money. The worst-case scenario is when your position is deeply rooted or you get liquidated directly; in this case, the rebate is like a shot of adrenaline, helping you recover some capital and leaving you a chance to breathe for subsequent trades. From this perspective, the rebate is truly an invisible weapon for traders.
