I think it would be better to use several bollinger bands and define 'extreme zones' within a current trend. As example: When the price is very much overbought during an established up trend, you start to buy. It would be still very risky but I guess it would work better than without 'extreme zones'.
Just figured out that it is already using extreme zones. Lovely idea BTW :)
