I try to create a two-tone Bollinger following phases.

It is no doubt very simple but I can not find why when changing colors there are holes ...

im uncertain if this is the answer but it appears to work. you;ve got to play around with the order of arrays and the condition of its price in order to get it to work correctly.

anyway u can see from the data window the prices appear funky.

give us an update if you got it figured out

Yes, your suggestion works by changing the order of arrays.
No longer persists that the delay the opening of the final table.

Thank you

  1. stanislass: why when changing colors there are holes ...
    stanislass: Yes, your suggestion works by changing the order of arrays. No longer persists that the delay the opening of the final table.
    Changing the order fixes nothing, you just hid the problem in one direction.
    You must connect the lines. You have red[5]=value, green[5]=empty, and then green[4]=value. Therefor red ends one bar before green begins, resulting in a gap. If green[5] is empty set it to the same value as red[5] and thus connecting the lines.
  2. if(ExtCountedBars>0){ExtCountedBars--;}
    No need for the decrement. Contradictory information on IndicatorCounted() - MQL4 forum
  3. You lookback is Periode (iBands) Do your lookbacks correctly.

Ahhhh okkkk ! 

I debuted in indicator.

I forgot that the route stops in the middle of the candle!

Thanks you two
