Indıcator buffer variables does not seem

[Rabia Yoruk]

hello, I have a problem when converting from mql4 to mql5. I would be glad if anyone can help. I can't find where I went wrong.

I have defined as follows:

#property indicator_buffers 15 

double buf_Open[];

int OnInit() {

        
   IndicatorSetString(INDICATOR_SHORTNAME,"usdind");

   SetIndexBuffer(8, buf_Open);
   SetIndexStyleMQL4(8, DRAW_NONE);
]

for the SetIndexStyle function (mql4), i used to convert it by using this article : https://www.mql5.com/en/articles/81

and in the OnCalculate function, all array values are available :

buf_Open[ind] = somefunc(ind, open[ind]); //I checked here and the data is coming as follows: 55.5454, 60.4343

however in the indicator window, the values next to the label show 0 (metatrader 5)

In similarly written mql4 codes, the data appears here: 

Thank you very much in advance.

#property indicator_buffers 2

   SetIndexBuffer(8, buf_Open);

You declare you have two buffers. Yet, you try to set the ninth.

You don't declare any plots.

yes, actually there are others but I took one as an example. Actual value is 15 for indicator_buffers i edited again now. And also i declare :

#property indicator_plots 15
