The spread of gold is the difference between the buying price and the selling price reported on the trading platform. When there are more orders, add a little price difference when you enter the market, because the disk shows the selling price. Add a little price difference when making more orders. Empty orders are added when they appear, because empty orders are sold at a high level first and then bought back at a low level, so the price difference is added when closing positions.

For example, the stop-loss and profit-taking of multiple orders is the price you see, because the price difference of multiple orders is already included when entering the market; However, when closing the position, the short position is added with a price difference of 0.5, so the take profit should be added with a price difference of 0.5. For example, if you are short at 1685, the stop loss is 1689, but the loss is actually swept at 1688.5, and the take profit will not be swept until 1679.5.
