Current position = current price * open interest
Open position = average open price * open interest
x", the average open price as "
y", the open position amount as "
z", and the current price as "
a", the short position is "
Average opening price * net position-current price * net position = global new debt = (y-v)*|a-b|
Global new debt = (y-v)*|a-b|
Then net position = |a-b|
Total position (total global debt) = a+b+c
Proportion of net position=|a-b|/(a+b+c) is set to "K"
Long position asset handling fee x = N + M * K;
K1-K=The impact of new positions on net positions
The actual long position handling fee x = (N + M * K) * (1+K1-K)
