int OnCalculate(const int rates_total,       // number of available bars in history at the current tick
                const int prev_calculated,   // number of bars, calculated at previous tick
                const datetime &time[],      
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])   {

    double yy[];
    yy = close[]; // error here, "invalid array access"
    // question: how to create a variable to point to a reference to dynamic double array? 

    // so that the yy can be used in the following way:
    // yy[0], yy[1], ....

}

i think you need to copy close[] to yy[]

nicolasxu:

double yy[];
//yy = close[]; // error occurs because the variable yy is not invoked as arrays, whereas yy is declared as an array (double yy[];)
//should:
yy[0]=close[0];
yy[1]=close[1]; // etc

3rjfx:
double yy[];
//yy = close[]; // error occurs because the variable yy is not invoked as arrays, whereas yy is declared as an array (double yy[];)
//should:
yy[0]=close[0];
yy[1]=close[1]; // etc

I see. Thanks!
