This Trading system gives buy and short signals when after Bollinger Bands got very narrow they spread out and the Close touches the band (top or bottom). Additionally the MFI has to confirm this volatility breakout. But please be carefull because some stocks suddenly change direction and in this case they really change!

When +DMI cross -DMI and first bar close above mid
Bollinger Band Then buy at Cross of Bar High
Remember most Important thing
Bar that close above mid BB is important
See that the close is within 15% of bar high and not less
Suppose Bar High is 100
Bar low is 90
Then Difference is 10
So 15% of 10 is 1.5
High – 1.5 = 100 – 1.5 = 98.50
So Close must be above 98.50
DMI VALUES ARE 14
BOLLINGER BAND (20,2)
