bb will work only when the market is trending,because its trend related indicator,stock market is not just trendind always ,80%of the price movements happenes in just 20%percent of the time.so 80% percent of the time market is just trading range or consolidation,only 20% percent of the time its trending,and again most of our trending markets happens over the night.so its imposible to make money bb,i think people will love to trade with bb because its very easy to understand theoratically,they do not like and dont want be with complex ones,but rememeber each and every movement in the markets we deal a difficult situations,so i name them as boring bands
