It is based in an EMA cross ( 9 x 21) and the Bollinger Bands without the central Moving Average.
I prefer to use the EMA cross in the middle of the bands.
It is also possible to activate "Colored Bars" to paint the candles according to the EMA cross: green if the candles are above both EMAs, white when at least one of them are in between EMAs and red if they are both below EMAs.
My operational works like this:
- Buy when price is above EMAs - Sell when price is belos EMAs
Of course, I use BB to give me the direction of the trend and I only enter in a trade when the price is in the same trend of the BB.
I avoid trades when the bands are getting narrowed.
I hope you enjoy my indicator and let me know if you have any suggestion! ;)
