In India, the stock market is very volatile and it is just not a cakewalk to make some quick buck trading stocks. Finding the best scanners will give you the edge, but stock market scanners are not cheap. They are far from it! To get the best scanners for free, you need to consider some considerations.
First, you need to understand technical and fundamental analysis. You have to have good knowledge about investment strategies and you have to have some money to invest. The free scans will make you understand the market better, but you will have to pay to use them. However, a lot of financial websites provide free scans but you need to sign up for their premium services to have them. Some stock market scanners will help you to track stocks in real-time and for free, but you will have to sign up with them and you can only watch the stock price data at that time.
