Now the brokerage commission can be extremely low, and the lowest can be 10,000741 too.
For investors with $1.5 million in capital, low fees are an important consideration when choosing a margin option. Regarding ** trading commissions, most brokerages currently only support a net commission rate of 1/10,000 (excluding transfer fees). This means that for every 100,000 yuan of trading volume, the commission is at least 10 yuan or more. However, in fact, the commission of 1.5 million funds can already achieve a very low cost price, that is, 10,000741, the same 100,000 yuan transaction, the handling fee only needs 741 yuan.
Secondly, regarding the financing interest rate, the current brokerage can already achieve a 5% rate, the larger the amount of funds, or the larger the financing transaction volume, the financing interest rate can continue to fall. Due to the limited number of securities borrowing, the rate that most brokerages can provide from their own securities sources is between 6% and 10%. When choosing a securities lending solution, you need to weigh it against your needs. If you anticipate the need for frequent securities trading, it may be more appropriate to choose a brokerage with a large absolute source of securities and a relatively small number of existing customers. In this way, you can reduce the trouble of grabbing securities and carry out securities lending and borrowing operations more smoothly. 
It should be noted that the securities sources of securities brokerages are divided into self-owned securities sources and external securities sources. The self-owned securities source is owned by the brokerage itself, so it is inversely proportional to the customer's risk.
When brokerages lend their own securities sources, they are actually gambling with customers, based on different judgments on the direction of the first and the return of costs and benefits. Therefore, the number of self-owned securities sources of brokerages is relatively limited. The external source of securities is borrowed by brokerages from other institutions**, although the number is large, but usually need to make an appointment, and it takes at least T+1 day to be funded, and the convenience is relatively low. To sum up, for investors with 1.5 million funds, when choosing a margin financing plan, they should comprehensively consider factors such as commission, financing interest rate, securities lending rate, and bond source. If you pay more attention to financing business, then it may be more suitable to choose a brokerage with low financing interest rate and convenient processing. If you need to conduct frequent securities lending transactions, then it may be more appropriate to choose a brokerage with a large absolute source of securities and a small number of existing customers. The following is the lowest commission rate that I summarized after sorting out the rate of 140 brokerages, which can be used for your reference, and if you have other questions, please feel free to comment on the comment area or communicate with private messages.
