The transaction cost of spot asphalt is generally divided into two parts, one is the opening fee and the other is the closing fee. The sum of the two is the total handling fee for completing a spot asphalt transaction! The handling fee standard is six ten thousandths of the transaction amount, which is charged once when you buy it and once again when you sell it, making a total of twelve tenths. This is just a handling fee, there is a difference. The price difference is the difference between the buying price and the selling price, and it is also the profit of the market maker.

Calculation method of spot asphalt handling fee;

Handling fee = opening fee+closing fee

Opening fee = opening price × contract unit × number of positions × rate

Closing fee = closing price × contract unit × number of positions × rate
