Bollinger Bands

Bollinger Bands has 3 lines:
A simple moving average (middle band, normally MA20) and an upper and lower band which are typically 2 standard deviations +/- from a 20-day simple moving average.

To be successful using Bollinger Bands:
1- Always follow the trend
2-Ride the massive trends by adding to your positions and good entry points.
3-Move SLs as you are riding the trend using the lower band for buy positions or upper band for sell positions.
4-Look for breakouts to enter trades.
