Bollinger Bands SE

Bollinger Bands SE is a signal that generates a short entry based on the high price crossing below the upper Bollinger Band.
In general, Bollinger Bands represent two standard deviations above and below the market. Prices within the standard deviations are considered to be 'normal' prices. Whenever the price moves above the upper band, this strategy generates a sell stop order for the next bar when the high price of the current bar has crossed back below the upper band. The stop value is the level of the upper Bollinger band.
You can change the number of bars and standard deviation used to calculate the Bollinger band.
