Do the math: The hidden costs of high-frequency traders
Assuming you are a moderately active short-term trader with an average monthly contract trading volume of 500,000 U, all using market orders (Taker):

No optimization at all: Transaction fee expenditure = 500,000 × 0.05% = 250 U
Annual cumulative: 250 U × 12 = 3000 U

This 3000 U transaction fee is your net expenditure cost, completely unrelated to whether you made or lost money in trading. Gains need to be deducted, and losses also need to be deducted.
So the question arises: Is there a way to save this money?
The answer is: Yes, and there are multiple methods. #手续费
