The outer disk reflects the buyer's wishes and the inner disk reflects the seller's wishes. If the inner disk is too large, it means that most of the buyers are willing to sell, which means that the seller is more powerful. If the inner disk and the outer disk are roughly similar, the buying and selling power is equal.
Understanding of domestic and foreign futures markets;
Through the size and proportion of the number of external and internal markets, investors can usually find out whether they are actively buying or actively selling. In many cases, they can find the trend of bookmakers, which is a more effective short-term indicator. However, investors should pay attention to the trading situation of low, medium and high futures prices and the total trading volume of this commodity when using external and internal markets.
Because the number of outer disk and inner disk is not valid at any time, many times the outer disk is large and the futures price does not necessarily rise; If the internal market is large, futures prices may not necessarily fall.
