Instead of charging traditional commissions, Huaan Futures primarily uses transaction ratios and opening/closing fees. For example, on the Zhengzhou Exchange, the transaction fee for methanol futures is 0.0003 of the transaction amount. On the Shanghai Exchange, gold futures incur an opening/closing fee of 60 yuan per lot. The use of transaction ratios makes it harder to estimate the exact cost of a trade without understanding the transaction amount. I find this structure beneficial for certain types of trades but complicated for others. As a trader, I always prefer a transparent and predictable commission structure, so I’d recommend checking the exact fees for the specific products you wish to trade.
