Nifty 50 Spot chart or future chart for intra day??

Shoul i watch nifty 50 Spot or future chart? How can we track volume if we watch and take decisions based on spot chart??

Depend on segment you are trading , if going with options you should go for spot and for futures there future chart . Both will difference in LTP. You dont have to trade on options by looking at volume as index constuituent of different stock almost 66% movement of price comes from there.
