Basicly we open position when price action touch the under or upper line of BB and go back,we set SL a few pips below the lowest or a few pips above the highest,than if we luckily make some pips then we put our new SL to the BE + a few pips. we close our position when the price action touch the opposite upper or under line.

I will show u what i mean by some chart.

Now let me tell u the details.
1A touch the upper or the under line of BB.
2A go back at once(for this case,PA should go back a lot,it depends on experience) OR PA go back next bar（for EURUSD,IF the goback bar >120pips than NO trade ).
3:Open at the next bar open,SL = the high of the bar that touch the BB upper line + a few pips(5pips e.g.） OR the low price of the bar that touch the BB under line - a few pips,say it's 80pips.（for EURUSD,IF the SL >120pips than NO trade ).
4:When you have 80 pips profits,move SL to BE + a few pips.
5:close the trade when PA touch the opposite BB upper or under line.

BTW,there is 5 bars per week in my daily chart,if your chart has 6 bars a week,you'd better use another broker.

The advantage of this system is it's simple and it has a Win/Lose ratio of 3:1(say a win trade is 300pips and a lose trade is -100pips),and what's more,the BB never repaint so you can backtest it easily.

Some trades...
