Sorry for n00b question but is there an index like sensex or Nifty that includes the sum total of the entire stock market?

Is there any indicator to track total buy volume and total sell volume?

Knowing how much volume is buy and how much volume is sell is the key to winning almost every trade. But, unfortunately, they won’t give you that data. However, if you contact law makers, and convince them to pass a law that require stock brokers to show you that buy/sell volume data. Then, you can make yourself rich very soon.
