Your the first person to ever ask me that :) All oscillators work pretty my the same BB%, stoch, MacD & RSI. I prefer to use BB% due to its direct relation to the Bollinger band, The line drawn indicate both divergence and break outs. But there are not really divergence in relation to the bollinger band they mirror each other. If you study a bollinger band price retreats from outside then inside = Reversal so in this case where price is a LH is in fact a HH in relation to the bollinger band then you have price showing a HH but in relation to the Bollinger band it is in fact a LH. = Reversal. Then if you connect all the highs (bumps) on the BB% from top to bottom when price cross over will be your precise break out point.
Its a little hard to explain but the same theory work with all oscillators.
