EA berdasarkan volume candle

logic BUY:
1.apabila candle pertama di TF 15 M ditutup di atas, dengan range minimal 30 point.
2.lalu buka candle berikutnya, naik 10 point langsung ambil posisi BUY.


logic SELL:
1.apabila candle pertama di TF 15 M ditutup di bawah, dengan range minimal 30 point.
2.lalu buka candle berikutnya, turun 10 point langsung ambil posisi SELL.

stop loss : 30 point
taking profit : 100 point
trailing stopnya : 20 point

NB: klo bisa, SL,TP,dan TS ( TrailingStop) nya di hidden.
dan jam tradingnya mulai jam 9.15 wita - 12.00 wita & dilanjutkan lagi trading jam 13.00 wita - 16.15 wita.

mohon bantuan revisi dan edit dari teman2 master yang mengerti MQL4.
