Ten hands. When the futures trading volume is large, it can affect the futures price, but it will not have any influence on the futures trend before ten lots, and the number of lots is too small. When the number of lots is large, that is, when the trading volume is large after ten lots, it will have some influence on the fluctuation of the futures market. For example, a futures product, because of its large position, will have a long main force and a short main force, and a trading action of the main force may cause fluctuations in a futures product market.
