What are the different types of foreign trade?

The main types of foreign trade include:

• trade in goods and services;

• exchange trade;

• trade fairs;

• auctions;

• counter trade;

• trading with compensation deals, etc.

I would like to distinguish the following types:

Exchange trade is a trade in goods, currency and securities through intermediary of brokerage exchanges. In 5-10% of cases it is real product, in 90-95% - futures.

Auction assumes sale in the form of a public market held in a predetermined place and at a pre-designated time with the right to a preliminary examination of goods. Goods by auction are sold of unique samples to the buyer who offers the highest price.

Barter. It is a natural commodity exchange, in which one thing is traded for another without monetary payment; a bargain, carried out under the scheme "goods for goods".
