I can't draw Envelopes on Array

New comment
 

Hi.

I can't solve this issue. I have to build an indicator that draws price ratio between two pairs and a Bollinger Bands or Envelopes.

I can draw Bolinger Bands without any problem but there is an issue drawing Envelopes...

Using debbugger seems that for cycle is not working properly.... Then I think there is an issue with EnvelopesOnArray syntax... Deviation must be an integer... I'm using now 1 and another value depends on user's choice...

This is the code:

//---- indicator settings

#property indicator_separate_window

#property indicator_buffers 6

#property indicator_color1 MediumBlue

#property indicator_color2 Red

#property indicator_color3 Red

#property indicator_color4 Green

#property indicator_color5 Green

#property indicator_color6 White

#property indicator_width1 2

//---- indicator parameters



enum Strategy{Envelopes,Bollinger};

enum Dev{Due=2,Tre=3,Quattro=4};

input Strategy Mode = 0;

input Dev Deviation = Due;

extern string FXPair1 = "EURUSD";

extern string FXPair2 = "GBPUSD";

extern int SignalMethod = MODE_SMA;

extern int SetPeriod=20;




datetime MostRecentBarStart;


//---- indicator buffers

double PriceRatio[];

double Upper1[];

double Upper2[];

double Lower1[];

double Lower2[];

double Center[];
