Stock trading is an activity which involves buying and selling. If one doesn’t want to lock his capital in the stock market he can be a Intraday trader. If one wants to gain from long term he can be an Investor for years. One can as well gain for shorter duration of few days, weeks or months.
An Investor gets Profit share.
One has the choice of trading his own capital (Cash) or trade with leverage (Intraday Spot & Derivatives).
One should switch to Derivatives (FnO) markets only with the understanding the much higher risk involved. One loses the flexibility in Cash/Equity markets because of predefined Lot size in FnO.
If one trades with higher probability of being rewarded, he is not gambling.
