Charts

#1
Hi trader gurus,
Am kinda beginner in stock market and have started investing recently.

I was going through this site for enhancing my trading prowess. It would be great if somebody can lemme know about different charts and their uses.

Is there any post regarding the same ?
Is there any way to find out which stock has given, say 20%, returns in last 3 months, 6 months etc...

Any response will be greatly appreciated.

Thanx,

Avinash
