The margin ratios 1.0 and 1.5 refer to the margin collection ratio.

1. A margin ratio of 1.0 means that investors need to pay a 10% margin at a fixed ratio based on the contract value. For example, if the value of a futures contract is 1 million yuan, then investors need to pay a margin of 100,000 yuan.

2. A margin ratio of 1.5 means that investors need to pay a fixed ratio of 15% of the margin based on the contract value. Taking the same futures contract of 1 million yuan as an example, investors need to pay a deposit of 150,000 yuan.
