Intraday analysis is the method of analysis to identify the stocks that needs to be traded(bought & sold) in the same day to make income/profit. Intraday analysis is based on market sentiment, i.e, Market direction, Sector contribution and selecting the stock trading with high volume.
The Intraday analysis follows the top down approach in selecting the stocks to be traded whereas in positional analysis the stock is picked first and analysis is done on it to identify the price movement.
