Take the first-hand Hang Seng Index contract as an example. If the current spot index of Hang Seng Index is 20,000 points and one point is HK$ 50, then the first-hand contract is equivalent to HK$ 20,000x50 = HK$ 65,438+HK$ 0,000,000 (one million). At present, the margin ratio of Hang Seng Index is roughly 16: 1(6%-7).

The small HSI is the HSI of 1/5, so the margin of the small HSI is 1.5-20000.

Take the Hang Seng Index (H-share index futures) of state-owned enterprises as an example. If the current spot of the state-owned enterprise index is 10000 points, and each point is HK$ 50, then by the same token, the first-level contract is 500,000, and the first-level deposit is about 40,000.
