Gambaran umum

Strategi ini menggunakan crossover rata-rata bergerak cepat dan lambat untuk menentukan posisi panjang dan pendek. Ini pergi panjang ketika MA cepat melintasi MA lambat dan menutup posisi ketika MA cepat melintasi di bawah MA lambat. Untuk mengejar keuntungan yang lebih tinggi, strategi mengadopsi mekanisme stop loss trailing. Alih-alih menetapkan harga stop loss tepat di bawah harga masuk setelah membuka posisi panjang, ia menetapkan harga stop loss trailing yang bergerak naik setelah kenaikan harga sampai penurunan harga mencapai batas harga stop loss.

Cara kerjanya

Strategi ini menggunakan garis Simple Moving Average (SMA) yang cepat dan lambat untuk menentukan entri dan keluar. Ketika SMA cepat melintasi SMA lambat, itu menandakan tren naik sehingga strategi menjadi panjang. Ketika SMA cepat melintasi di bawah SMA lambat, itu menandakan pembalikan tren sehingga strategi bersiap untuk menutup posisi.

Untuk memaksimalkan keuntungan, strategi ini memperkenalkan mekanisme stop loss trailing. Alih-alih menggunakan harga stop loss tetap setelah membuka posisi panjang, ia menetapkan harga stop loss trailing yang bergerak naik setelah kenaikan harga. Setiap kali harga naik sebesar persentase tertentu, harga stop loss trailing disesuaikan dengan persentase yang telah ditentukan sebelumnya. Ketika harga menarik kembali dan mencapai harga stop loss trailing, itu memicu perintah stop loss untuk menutup posisi.

Secara khusus, harga stop loss trailing dihitung sebagai berikut:

Harga Stop Loss Trailing = Harga × (1 - Persentase Stop Loss Trailing)

Stop Loss Trailing Percentage didefinisikan oleh parameter strategi Deviation %. Strategi menghitung kembali harga stop loss trailing pada setiap bar yang ditutup. Harga stop loss trailing baru tidak dapat lebih rendah dari bar sebelumnya, sehingga memastikan harga stop loss hanya bergerak ke atas, bukan ke bawah.

Ketika harga turun dan mencapai harga stop loss, ini memicu sinyal penutupan dan posisi akan ditutup dengan pesanan pasar.

Keuntungan

  • Gunakan rata-rata bergerak ganda untuk menentukan arah tren dengan hasil backtest yang baik
  • Mengadopsi trailing stop loss untuk mengejar keuntungan yang lebih tinggi
  • Periode rata-rata bergerak yang dapat disesuaikan dan persentase stop loss trailing
  • Stop loss line terus bergerak naik ketika tren naik, mengunci di sebagian besar keuntungan
  • Cepat menghentikan kerugian ketika tren berbalik untuk menghindari kerugian lebih lanjut

Risiko dan Solusi

  • Waktu penyeberangan rata-rata bergerak yang tidak tepat dapat menyebabkan sinyal palsu. Uji parameter yang berbeda untuk menemukan kombinasi MA optimal
  • Mengatur parameter stop loss trailing persentase stop loss yang terlalu agresif dapat dihentikan secara prematur.
  • Jurang harga dapat langsung menembus harga stop loss. Pertimbangkan untuk menggabungkan indikator lain untuk menilai tren dan menghindari perdagangan selama periode berkisar

Arahan Optimasi

  • Uji parameter periode rata-rata bergerak yang berbeda untuk menemukan kombinasi optimal
  • Uji parameter persentase stop loss trailing yang berbeda untuk menemukan tingkat stop loss optimal
  • Menambahkan indikator lain untuk menangguhkan perdagangan selama periode rentang untuk menghindari dipengaruhi oleh peristiwa sporadis

Kesimpulan

Strategi ini menggabungkan indikator rata-rata bergerak untuk menilai arah tren dan mekanisme stop loss untuk mengunci keuntungan, berkinerja baik pada data pelatihan. Dengan mengoptimalkan parameter dan mengendalikan risiko, strategi ini memiliki potensi untuk mencapai keuntungan yang stabil. Namun, tidak ada strategi yang dapat sepenuhnya menghindari kerugian.

//  Description
//  =============================================================================
//  This strategy will go long if fast MA crosses over slow MA.
//  If the 'Enable Trailing` is checked then the strategy instead of exiting from the position
//  directly it will follow the price upwards (percentagewise) with small steps
//  If the price drops by this percentage then the exit order will be executed
//
//  The strategy has the following parameters:
//
//  Fast SMA Length - How many candles back to calculte the fast SMA.
//  Slow SMA Length - How many candles back to calculte the slow SMA.
//  Enable Trailing - Enable or disable the trailing
//  Deviation % - The step to follow the price when the open position condition is met.
//  Source Exit Control - The source price to compare with the exit price to trigger the exit order when trailing.
//
