Trading is essentially the exchange of goods and services between two entities. It is the basic principle which forms the core of all economic societies and financial activities.
Trade governs the wheels of progress in any society and allows for wealth creation. A place where any form of trade takes shape is called a market. Depending on the kind of products, the market is defined. For instance, a place where stock trading takes place is called the stock market.
There are primarily two forms of the market – organised and unorganised. Organised market is constituted with a set of rules and regulations which every entity operating in the market needs to adhere to and usually consists of a regulatory body to supervise such adherence. An unorganised market does not contain any strict rules and regulations, and even if it does, adherence is not mandatory.
With online trading and investing, the process has become much more convenient, where most markets have been simulated on the internet.
Trade has existed for as long as the human civilisation, i.e. the agricultural revolution. The form of trading, however, has varied across different societies. Primarily due to isolated human communities which did not allow the unification into a single system.
