### Example

In the above image we can see that the BOLL block is triggered when the price goes under the lower BAND.  
Because the signal type is **Below,** the trigger is **Position** (it could have worked with Crossover as well in this case) and we are analyzing the **Lower Band**, other bands are not analyzed in this example.  
This Block can be really efficient combined with other block like MAs, [more on Moving Average here](https://blog.kryll.io/moving-average-blocks---how-they-work--part-1-/).

**Conclusion**  
Bollinger Bands® do not constitute a standalone trading system. They are simply one family of indicators designed to provide traders with information regarding price volatility. John Bollinger suggests using them with two or three other non-correlated indicators that provide more direct market signals. He believes it is crucial to use indicators based on different types of data.

**Happy Trading!**
