Applying called indicator to chart
Create an indicator buffer and simply fill it with iBands() values.
I tried that I couldnt get it to work I always have a hell of a time writing indicators all I 'm getting is a horizontal line how do I get this indicator to use the previous values from all the previous bars do i need to create an array of the bollinger bands previous values or something like that ?
#property indicator_chart_window #property indicator_buffers 1 #property indicator_color1 Blue double Buf_0[]; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { //---- indicators SetIndexBuffer(0,Buf_0); SetIndexStyle (0,DRAW_LINE,STYLE_SOLID,2); //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { int i, counted_bars=IndicatorCounted(); //---- i=Bars-counted_bars-1; while(i>=0) { Buf_0[i]=iBands(NULL,0,3,2,0,1,1,0); i--; } //---- return(0);
I changed the line with the buffer to shift the bands by "i"
Buf_0[i]=iBands(NULL,0,3,2,0,1,1, i );
it appears to work this way is that how it should be done ?
int start() { int i, counted_bars=IndicatorCounted(); //---- i=Bars-counted_bars-1; while(i>=0) { Buf_0[i]=iBands(NULL,0,3,2,0,1,1,i); i--; } //---- return(0); }
I changed the line with the buffer to shift the bands by "i"
Buf_0[i]=iBands(NULL,0,3,2,0,1,1, i );

u teel me

Buf_0[i]=iBands(NULL,0,3,2,0,1,1, i );

OK thanks it works then, I just wasn't sure if that should be done in the start function or not, I didn't want it re calculating all those bars every tick

i=Bars-counted_bars-1; while(i>=0)

If a custom indicator uses values from a 2nd indicator, is it possible to attach that 2nd indicator on the chart from within the customer indicator without replicating the code of the 2nd indicator in the custom indicator ?
For instance if my customer indicator uses values from a bollinger band and I want that bollinger band to be seen on the chart, is there a way to apply the bollinger bands to the chart from within the customer indicator without replicating the BB code within the custom indicator ?
