With the help of the Scanner, analysis of profitable trades will be easier.


We should not use the scanner as the only way to get a profitable trade. To make the accuracy level higher, traders must also trade with much discipline. Trade each stock with the same value. Like if you are trading both SBIN and Reliance with our open high low scanner, trade both the stock for say Rs. 50000. Many traders make the mistake and trade say 100 SBIN as well as 100 Reliance. Instead keep the trade size same. Trade limited number of stocks as you may not be able to handle many trades at a time.
