Bollinger Break out

[ggutierrez]

I am looking for a file that can tell me to "SELL" when ever a candle CLOSES above the top band and tells me to "BUY" when ever price CLOSES below the bottom band.

I would like to see all files related to this indicator/signal

Because i would like to visioully SEE "BUY" and "SELL" words on the screen if possible.

thakn youy for all your help
