Intraday analysis is nothing but buying and selling the stocks on same day itself. If in the morning, we should see the trend of Asian market and if it is noon and we should see the trend of European market. After which, we have to look the trend of FII (Foreign Institutional Investors). In NSE website, we need to check the Advance & Decline which is high. If all are in positive, then we should go and check which sector is doing well and which company is doing well in that particular sector. This is how we need to pick the stock.The same is for losers.
