1.8 cover different tools a trader can use to help them make trades. whether it be for charting, news, scanners with realtime data.

charting is good for recognizing patterns. patterns are made up of some indicators that make up a certain movement more likely then not. 

news is a factor that can effect the stock.

scanners are used to not just to find stock but to filter out all the stocks that do not match your criteria. 

out of the all the ones they recommended i would use STT and the news from yahoo finance but i think thats about it.

again my main focus is just absorbing the lessons as they come by reflecting on their practical application.
