Your settings are correct.
Re the MACD :
The trigger or signal line which you set at 14 (normally set a 9) is
not a sma but rather another ema. ie
all the moving averages in the MACD are exponential,
not simple.
The trigger line is not used in this method and you can make it invisible or delete it.
Now, be careful upon entry - the system is
contrar-ian.
That is, enter
only when a tag (touch or,..... better - spike thro) of the upper band is made with a
negative MACD. ie below zero.
A
lower tag entry is made with a
positive MACD.
Watch out that these opposites do not trick or confuse you - this can happen easily if you are not careful!
You timeframe is good - use anything from 15 minutes like Dobro did, thro to 1 hour.
