John Person  in a short Traders Interview video  is presenting first  a definition for Pivot Points then he mentioned few tips regarding the use of Pivots as a support and resistance levels in a bullish market ..

In my opinion Pivot Points is a tool can be used successfully in trading any market but can't be a stand alone system .. another words you need to integrate Pivots with other trading tools like Candlesticks Patterns , Elliott Wave or any other trading tool you prefer to get better results for your trading account .. ☺
