Futures have closing price and settlement price. If you are multithreaded, at the closing time, it is 35 10, and you are more than 34 10. So you earned 100 points. But futures have a settlement price, that is, the average price of all-day trading. This price may be higher than the closing price or lower than the closing price. Below the closing price, it means that you may not earn 100 points. This will give us the illusion that the cost of holding positions has increased.
