using broad market indicators

hi, how do i use broad market indicators?

like these:
UpDown Vol Ratio
UpDown Vol spread( advance volume - decline volume)
UpDown Vol money spread( aUpDown Vol spread* typical price)
TRIN
ADSpread
ADRatio

one thing i could think of is smoothing them up wth 13 EMA and look for divergences.

another idea is that buy stocks which advance during a high broard market decline day. This might mean the stock is bullish on bad days and on good days it will fly!

the indicator that interests me most is UpDown Vol money spread. it shows funds pushing stock up or down. but i got no idea how to use it

well i really dont know. Please help =)
