I Understood the post as:
1. All indicators are based on "price and volume", like atta and maida z two different products based on wheat only.
2. some indicators z good in trending market only, some in sideways, some only in crude oil, but fails when used in agri commodities etc etc.
3. so there is no "1" universal indicator.
4. most reliable and relevant in all market is the current price i.e high,low,close,open, and volume.
