One price change of 30-year US debt is 1/32( 100 index), and 32 prices in the same direction are 1 larger.

Every 1/32 points (100 point index), that is, the price change of 1 is the profit and loss of 3 1.25 USD.

I want to know what 99-02 and 99- 16 in your example mean. Do you mean 99- 16/32?

If it rises to 99- 16/32 on February 32, the long profit of each 1 contract is

3 1.25 USD X 14 Price change (i.e. 1400 index point) =437.5 USD.

The value of each contract of 30-year US debt is 654.38 million+USD.

The deposit is generally 4000-5000 dollars (depending on the brokerage company, the deposit collection is different)

I hope I can help you, and I hope to adopt it!
