Bollinger and trend corrections

This Expert Advisor determines the trend and corrections. It also uses the Bollinger indicators to confirm trades. It can perform trades on three trend corrections (or not use the corrections). It can also display them on the chart (if the information display is enabled). The EA has a lot of options, it can transfer trades to breakeven, set stop loss right after a trade is opened.
