CHIKOU SPAN line return 0

 

Hello,

 

  i don't knew why MODE_CHIKOUSPAN return 0 usually 

 i use this code : 

double CHIKOUSPAN=iIchimoku(NULL,0,9,26,52,MODE_CHIKOUSPAN,0); 

 

 waiting for help 

 

thanks 

 
Put it on a chart and look. The Line ends 26 bars earlier.Ichimoku
 

Last parameter is 27

double CHIKOUSPAN=iIchimoku(NULL,0,9,26,52,MODE_CHIKOUSPAN,27);
