Hello Manolo,
What you say is basically true I think, but the snipers MAs do move outside of the bollinger bands fairly regularly.
The bollinger upper and lower bands are calculated by using the square root of the sum of the squares of the deviation from MA for the last 20 periods usually. Also, they are calculated by using the closing prices.
The Snipers bands are calculated by using the highs and the lows, so in periods of higher short term volatility, these bands may move outside of the bollinger's.
Depending on conditions there will be different types of combination breaks.
Candle wick breaks BB, candle wick breaks SnipersMA
Candle wick breaks BB, candle body breaks SnipersMA
Candle body breaks BB, candle body breaks SnipersMA
Candle body breaks BB, candle wick breaks SnipersMA (very rare, I should think)
I would imagine that these different combination breaks will be used to indicate the more trustworthy signals. Possibly help to differentiate between continuation and reversal signals.
I think that we should look at learning a strategy to trade Forex, should be compared to learning a language.
Imagine a teacher trying to introduce ABC's to a class of students. This is the first step in the students' education, necessary and the initial building blocks of the course.
If the students bombard the teacher with questions about conjugating verbs etc, before they have absorbed the basics, the lessons will become disjointed, the class becomes confused and many will give up because it is "just too difficult to grasp".
Vahid has just started to introduce this strategy to us and I think that we have to trust him to explain all in a coherent manner that allows us to learn without getting (too) confused. We should all sit on our hands for a while and resist the urge to ask too many questions without first allowing Vahid the opportunity to follow his teaching strategy

Good luck
Keith
