John Bollinger developed Bollinger Bands® in the early1980s and since their introduction they have become one of the most widely used technical indicators worldwide. Bollinger Bands earned their popularity because they are so effective in helping traders assess expected price action-information vital to trading profitably. Bollinger Bands can be applied in all the financial markets including equities, forex, commodities, and futures and they can be used in most time frames from very short-term periods, to hourly, daily, weekly or monthly.
