Ringkasan

Strategi ini merancang garis stop loss bergerak dan garis pembalikan berdasarkan indikator Average True Range (ATR). Ia akan mengikuti stop loss berdasarkan pergerakan harga. Khususnya, jika pergerakan harga melebihi 1%, stop loss akan bergerak ke arah keuntungan pada perkadaran tetap. Apabila harga memecahkan garis stop loss, kedudukan akan ditutup secara automatik. Ini dapat mengunci keuntungan dan mengurangkan kerugian.

Logika Strategi

Strategi ini menggunakan penunjuk ATR untuk mengira garis stop loss. Rumus khusus adalah:

atr = multplierFactor * atr(barsBack)

longStop = hl2 - atr  
shortStop = hl2 + atr

Di mana multiplierFactor adalah pengganda ATR, dan barBack adalah tempoh ATR. Semakin besar nilai ATR, semakin besar turun naik pasaran.

Garis stop loss longStop dan shortStop dikira berdasarkan nilai ATR. Isyarat perdagangan diaktifkan apabila harga melebihi kedua-dua garis ini.

Di samping itu, pembolehubah arah diperkenalkan untuk menentukan arah trend:

direction = 1 
direction := nz(direction[1], direction)
direction := direction == -1 and close > shortStopPrev ? 1 : direction == 1 and close < longStopPrev ? -1 : direction 

Jika arah adalah 1, ia menunjukkan trend menaik. Jika arah adalah -1, ia menunjukkan trend menurun.

Berdasarkan nilai pembolehubah arah, garis stop loss dengan warna yang berbeza akan digambar:

if (direction == 1)
    valueToPlot := longStop
    colorToPlot := color.green
else  
    valueToPlot := shortStop 
    colorToPlot := color.red  

Ini jelas menunjukkan arah trend semasa dan kedudukan garis stop loss.

Penghentian Kerugian

Titik utama strategi ini adalah pengenalan mekanisme stop loss yang boleh menyesuaikan garis stop loss dalam masa nyata berdasarkan pergerakan harga.

Logiknya ialah:

strategyPercentege = (close - updatedEntryPrice) / updatedEntryPrice * 100.00
rideUpStopLoss = hasOpenTrade() and strategyPercentege > 1 

if (rideUpStopLoss)
    stopLossPercent := stopLossPercent + strategyPercentege - 1.0
    newStopLossPrice = updatedEntryPrice + (updatedEntryPrice * stopLossPercent) / 100
    stopLossPrice := max(stopLossPrice, newStopLossPrice)
    updatedEntryPrice := stopLossPrice

Jika harga meningkat lebih daripada 1% berbanding harga kemasukan, stop loss akan ditarik ke atas. Julat penyesuaian adalah bahagian yang melebihi 1%.

Ini boleh mengunci lebih banyak keuntungan sambil mengurangkan kerugian.

Analisis Kelebihan

Berbanding dengan strategi stop loss bergerak tradisional, kelebihan terbesar strategi ini ialah ia dapat menyesuaikan garis stop loss secara dinamik mengikut keadaan pasaran.

  1. Mencapai kunci keuntungan yang lebih tinggi di pasaran trend

    Mekanisme Stop Loss Trailing membolehkan garis stop loss terus bergerak ke arah keuntungan. Ini mengunci keuntungan yang lebih tinggi apabila pasaran terus menguat.

  2. Mengurangkan risiko jurang stop loss di pasaran terhad julat

    Apabila trend pasaran berubah, stop loss bergerak tetap cenderung untuk dilewatkan. manakala garis stop loss strategi ini dikira berdasarkan turun naik pasaran, yang dapat dengan munasabah menjejaki perubahan harga dan mengelakkan di melewatkan dalam penyatuan.

  3. Operasi mudah, mudah untuk automatik

    Strategi ini sepenuhnya berdasarkan pengiraan penunjuk tanpa logik penilaian trend yang kompleks.

  4. Parameter yang boleh disesuaikan yang sesuai untuk produk yang berbeza

    Parameter seperti tempoh ATR, faktor pengganda, peratusan stop loss boleh disesuaikan. Strategi boleh dioptimumkan untuk produk yang berbeza untuk menjadikannya lebih serba boleh.

Analisis Risiko

Walaupun strategi ini mempunyai banyak kelebihan, risiko berikut harus diperhatikan:

  1. Tidak dapat menentukan titik pembalikan trend, terdapat risiko membeli tinggi dan menjual rendah

    Tidak ada logik dalam strategi ini untuk menentukan sama ada trend telah berakhir. Ia cenderung untuk membeli tinggi dan menjual rendah pada akhir pasaran lembu.

  2. Tetapan parameter yang tidak betul boleh memperkuat kerugian

    Jika parameter tempoh ATR ditetapkan terlalu pendek, garis stop loss akan terlalu sensitif dan mungkin sering dipicu oleh pasaran berayun.

  3. Risiko terhalang daripada memancing bawah

    Strategi ini tidak menganggap titik-titik penting sebagai sokongan stop loss.

Untuk menangani risiko di atas, pengoptimuman boleh dilakukan dalam aspek berikut:

  1. Menggabungkan penapis trend untuk meramalkan pembalikan trend terlebih dahulu

  2. Ujian pengoptimuman parameter untuk memilih kombinasi parameter optimum

  3. Memperluas julat stop loss berhampiran tahap sokongan tertentu

Arahan pengoptimuman

Terdapat ruang untuk mengoptimumkan lagi strategi ini:

  1. Masukkan pengenalan corak candlestick

    Mengenal pasti beberapa corak lilin khas seperti perpecahan dan bintang jatuh untuk menilai kemungkinan pembalikan trend. Ini dapat mengelakkan risiko membeli tinggi dan menjual rendah.

  2. Pengoptimuman dinamik parameter pengangkutan

    Membolehkan parameter seperti tempoh ATR dan faktor pengganda berubah secara dinamik. Gunakan tempoh ATR yang lebih lama dan julat stop loss yang lebih luas di pasaran yang banyak turun naik.

  3. Menggabungkan model pembelajaran mesin

    Menggunakan LSTM, RNN dan model pembelajaran mendalam yang lain untuk meramalkan julat harga masa depan yang mungkin dan menyesuaikan jarak stop loss secara dinamik.

Ringkasan

Ringkasnya, strategi ini menggunakan penunjuk ATR untuk merancang garis stop loss bergerak, dan memperkenalkan mekanisme stop loss yang boleh menyesuaikan kedudukan stop loss dalam masa nyata berdasarkan perubahan pasaran. Ini mencapai kunci keuntungan yang lebih tinggi sambil juga mengurangkan risiko. Dengan pengoptimuman lanjut, strategi ini boleh menjadi lebih adaptif kepada pelbagai situasi pasaran dan berfungsi sebagai strategi perdagangan yang kukuh.

//  Description
//  ===========

//
//  INITIAL STOP LOSS - Where can isert the value to first stop.
//  POSITION TYPE - Where can to select trade position.
//  ATR PERIOD - To select number of bars back to execute calculation
//  ATR MULTPLIER - To add a multplier factor on volatility
//  BACKTEST PERIOD - To select range.
