Intraday analysis is a method which uses top down approach to trade stocks (to buy & sell or vice versa) on the same day to make profit.This method relies much on the market sentiment ,market direction,Sector contribution and selecting the stock trading with high volume .
This method differs from positional analysis where we study the charts,understand demand&supply to know about the price movements of the stock picked.Trading need not to be completed in one day, we can hold the stock for long period.
