Inner disk and outer disk are two relative words. Generally speaking, if it is the inner and outer disk in futures, then the inner disk is actively sold and the outer disk is actively bought, which represents the seller's market and the buyer's market in futures trading.

Of course, futures not only have internal and external markets, but also stock trading has internal and external markets. The internal market is represented by S, which means selling, and the external market is represented by B, which means buying.

Here's a detailed introduction to the inner disk and outer disk in futures:

1, futures inner disk

The number of transactions in which the seller voluntarily placed an order to sell the futures contract at the current price lower than or equal to buy one, buy two and buy three is shown in green.

If the transaction price is the entrusted purchase price, it means that the sale is more active.

2. Futures outer disk.

The number of transactions in which the buyer voluntarily placed an order to buy a futures contract at a price higher than or equal to the current price of selling one, selling two and selling three is shown in red.

If the transaction price is the entrusted selling price, it means that buying is more active.

Generally speaking, the inner disk and the outer disk are the difference between buying a house and selling a house. If investors want to analyze the market trend of futures, they can refer to the data of internal and external markets.
