A major downside is that ShenYin & WanGuo’s services are predominantly focused on the Chinese domestic market. This restricts access for international traders who may be looking to trade global futures or foreign exchange markets. Additionally, while the broker offers various instruments, the complexity of the fee structure can be a challenge for traders, especially for those who are not familiar with Chinese futures trading. From my experience, these limitations make it less appealing for traders looking for a broader international market or simple fee structures.
