Multi Formula Combination

[rahul100]

Hi

Does anyone know how to create a multi conditional formula, ie ...

If any of the 2 below are a sell then signal = sell
if any of the 2 below are a buy then signal = buy
if not nothing ... but i persume it should always be one of the 2 options above?

PP: CCIMODIFIED
PPIVOT ROTATION
PP:BOLLINGER BANDS.

OR a combination of any other 3 indicators.

Thanks in advance
