Stock market indicators are essentially quantitative tools applied by traders and investors to interpret financial data. The broad intent is to forecast stock market movements and make profits out of the same.
Even when a broker claims that trading in futures and options is free of cost, it is not free. Even the low-cost brokerage houses make cash trading in delivery free of cost but brokerage on futures is charged.
Futures and options are known as derivative products, which mean that they derive their value from an underlying commodity or asset. However, futures and options differ in fundamental ways from each other.
