Difference between spot and derivative trading.
Future ,call option,Put option.
Option –
Buyer getting the right to buy is call option (he will get money if the price goes above strike price)
Buyer getting the right to sell is put option (he will get money if the price goes below strike price)
In both above case seller gets premium.
Derivative market are risky than spot market,because rare chance in spot market the share becomes zero bout it will happen in derivative market
