Judging from the current contract value and margin letter of primary stock index futures, the primary demand is above 654.38+10,000 yuan to around 200,000 yuan. Stock index futures is a contract, which is different from product futures. The futures of copper, aluminum and other products are 5 tons, and the primary grain is 10 tons. A contract of stock index futures is that the Shanghai and Shenzhen 300 Index (points) is multiplied by 300 yuan, and then calculated according to the 8% margin.

First-hand accounting method of stock index futures;

Stock index futures are based on the Shenzhen-Shanghai 300 Index, and the margin letter is initially set at 15% for each 300 yuan. The accounting formula is: entrusted price (approximately equal to the index at that time) * price per point (300 yuan) * deposit letter (15%).

For example, the 1007 contract is now 27 18.2, the primary value = 2718.2× 300 = 81.54 million, the margin is about 15%, and the primary demand margin of stock index futures = 8/kloc.

If the minimum trading margin specification is 12%, the margin required by futures companies will generally increase by a few percentage points on this basis. Excluding the transaction fee, investors will buy funds with a primary contract demand of about150,000 yuan.

Extended data:

Stock index futures also need to choose trading orders in the process of placing orders. There are three kinds of trading orders, namely, market order and other orders stipulated by limit orders and the Exchange.

1, market price instruction

A market order refers to an order with unlimited price and trading according to the best quotation that can be executed in the market at that time. The unfinished part of the city plus instruction will be automatically revoked.

The characteristics of the market order are: the transaction speed is fast, and once the order is placed, it cannot be changed. Therefore, if the market fluctuates greatly, the transaction price may deviate from the expected price, so investors should use the market order carefully.

2. Limit order

The characteristic of limit orders is that they can be sold at the expected price of investors, but the transaction speed is relatively slow, and sometimes even impossible. When using a limit order, investors must specify a specific price.

3. Other explanations stipulated by the Exchange.

In order to meet the needs of future development, the exchange may introduce some new instructions with the development of the market to maximize the convenience of investors.
