has any one tried this before?

I have thort about this alot, i think i have a good idear!

take a big oscilator based on a large period for the main trend and ask which way is it going?

say it is going down....

take another of the same oscilator, this time of a small period for small spikes.

then add the small values into the big one as a new oscilator line but only when the small is going down (and throw away the rest(up))

then you should have a more powerful less confusing oscilator. (by only showing the new line)

has any one tryed this before?

Lag.

Huh?

He means that what you're looking at will incur a lot of lag time between the signal you get and the actual price movement. IE, most of the price movement will already be over by the time you get your signal.
