I disagree that you can not only use support and resistance by its own..

In fact many successful traders only use S/R for their trading as well as using price action.

I agree It is important to make decisions using different time frames when analysing S/R.

You can learn a lot by looking at a chart with candlesticks ONLY.

Ive come to desicions and was able to analyse more quickly by just looking at a candlestick only chart on occasions.
