Need help to code EA for Mql5

[vastavista]

Salam..

Siapa sini mahir MQL5...?saya nk convert indicator jadi EA..Tpi blum berhasil..

Sebab OnCalculate hanya untuk indi sahaja..Bila nk jadikan EA kena pakai OnTick pulak..bila guna dua2 tk boleh..

Masalah nya code ni tk boleh pakai dlm EA..kena pkai yg lain...

int OnCalculate(const int rates_total,
                const int prev_calculated,
                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[])
{
   ArraySetAsSeries(Time, true);
   ArraySetAsSeries(High, true);
   ArraySetAsSeries(Low, true);
   ArraySetAsSeries(Close, true);
   ArraySetAsSeries(Open, true);
