Which trading is better stock market or commodity

It depends, whether you ask for investment purpose or just wants to know, If you asking for the investment purpose or just for knowledge then it all depends upon you in which you want to invest whether it is stock or commodity because as my knowledge both are equally good.
A commodity is an economic good or service that has full or considerable replaceable: that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them.
The price of a commodity good is typically resolute as a function of its market as a whole: well-established physical commodities have actively traded spot and derivative markets. Most commodities are raw materials, basic resources, or agricultural products, like iron ore, sugar, or rice.
An electronic trading platform helps in creating a transparent price discovery device on the commodity futures exchanges without any involvement by sellers or buyers.
A speedy demand for a commodity can see increases in prices significantly from time to time. It is the best way or gives lots of chance to make money quickly and safely.
Change or Diversification is when you invest in a variety of industries that give results differently to changes in the market. It will keep your annual profit stable and also avoid big losses.
If you want to start trading then you can start by yourself or you can take help of any advisory firm like KHELOMCX, BAZAARTRADING advisory firm, 100MCXTIPS. Generally, I prefer BAZAAR TRADING, from their advice I earn the bigger profit, they provide the best technical and fundamental analysis in stock trading and commodity from experts.
