By doing this, you can easily increase thousands of dollars each month. Have you calculated the fixed cost of a transaction, which is the transaction fee? Taking futures contracts as an example, suppose you use $100 and leverage 50 times. That means you are using $5000 to either short or go long. The transaction fee on most exchanges is generally around 0.04%. This means you need $2 to open a position and $2 to close it. Just like that, without doing anything, you have already spent $4 in fees from your $100 principal. If you open 5 trades in a day, that’s $20 in fees. If you go back and forth with 10 trades in a day, your $100 principal could incur an astonishing $40 in fees. If you open 20 trades, the fees are basically on par with your principal, and many high-frequency traders end up paying more in fees than their principal over the course of a month. If you want to see your transaction fees for the past year, you can refer to the information I posted below. If you have a commission rebate, the fees can return a portion to you, and the money saved can definitely add up to a significant amount. Don’t throw it away anymore.
