Dalam isu ini, kami akan membincangkan
Demi kesederhanaan reka bentuk, kita tidak akan menggunakan Eksponensial Purata Bergerak yang disenaraikan dalam video, kita akan menggunakan ta.ema terbina dalam pandangan perdagangan sebaliknya (ia sebenarnya sama).
Ini adalah penunjuk pada Trading View, kita perlu pergi ke Trading View dan mengambil kod sumber.

Indikator EMA: strategi menggunakan dua EMA, satu adalah garis cepat (parameter tempoh kecil) dan yang lain adalah garis perlahan (parameter tempoh besar).
perjanjian kedudukan panjang Garis cepat berada di atas garis perlahan.
perjanjian kedudukan pendek Garis laju berada di bawah garis perlahan.
Indikator VuManChu Swing Free: Indikator VuManChu Swing Free digunakan untuk menghantar isyarat dan menilai sama ada untuk meletakkan pesanan dalam kombinasi dengan keadaan lain. Ia dapat dilihat dari kod sumber indikator VuManChu Swing Free bahawa pembolehubah longCondition mewakili isyarat membeli dan pembolehubah shortCondition mewakili isyarat menjual. Kedua-dua pembolehubah ini akan digunakan untuk penulisan keadaan pesanan seterusnya.
Sekarang mari kita bercakap tentang keadaan pencetus khusus isyarat perdagangan:
Peraturan untuk memasuki kedudukan panjang: Harga penutupan garis K positif harus berada di atas garis cepat EMA, kedua-dua EMA harus menjadi kedudukan panjang (garis cepat di atas garis perlahan), dan penunjuk VuManChu Swing Free harus menunjukkan isyarat beli (longCondition adalah benar).
Peraturan untuk memasuki kedudukan pendek (berbeza dengan kedudukan panjang): Harga penutupan garis K negatif harus berada di bawah garis pantas EMA, kedua-dua EMA harus menjadi kedudukan pendek (garis pantas di bawah garis perlahan), dan penunjuk VuManChu Swing Free harus menunjukkan isyarat jual (shortCondition adalah benar).
Adakah logik perdagangan sangat mudah? Oleh kerana video sumber tidak menentukan profit stop dan loss stop, saya akan menggunakan moderat profit stop dan loss stop kaedah bebas, menggunakan titik tetap untuk stop loss, dan mengesan profit stop.
Kod untuk indikator VuManChu Swing Free, kami masukkan ke dalam kod strategi kami secara langsung tanpa sebarang perubahan.
Kemudian sejurus selepas itu, kita menulis sekeping kod bahasa Pine yang melaksanakan fungsi perdagangan:
// extend
fastEmaPeriod = input(50, "fastEmaPeriod") // fast line period
slowEmaPeriod = input(200, "slowEmaPeriod") // slow line period
loss = input(30, "loss") // stop loss points
trailPoints = input(30, "trailPoints") // number of trigger points for moving stop loss
trailOffset = input(30, "trailOffset") // moving stop profit offset (points)
amount = input(1, "amount") // order amount
emaFast = ta.ema(close, fastEmaPeriod) // calculate the fast line EMA
emaSlow = ta.ema(close, slowEmaPeriod) // calculate the slow line EMA
buyCondition = longCondition and emaFast > emaSlow and close > open and close > emaFast // entry conditions for long positions
sellCondition = shortCondition and emaFast < emaSlow and close < open and close < emaFast // entry conditions for short positions
if buyCondition and strategy.position_size == 0
strategy.entry("long", strategy.long, amount)
strategy.exit("exit_long", "long", amount, loss=loss, trail_points=trailPoints, trail_offset=trailOffset)
if sellCondition and strategy.position_size == 0
strategy.entry("short", strategy.short, amount)
strategy.exit("exit_short", "short", amount, loss=loss, trail_points=trailPoints, trail_offset=trailOffset)
A.Itdapat dilihat bahawa apabila buyCondition adalah benar, iaitu:
Tiga syarat untuk bertahan lama.
B.Apabila sellCondition adalah benar, tiga syarat untuk membuat kedudukan pendek berlaku (tidak diulangi di sini).
Kemudian kita menggunakan fungsi strategi.entry untuk memasuki dan membuka kedudukan dalam kes jika keadaan penghakiman isyarat pencetus, dan menetapkanstrategy.exitfungsi untuk menghentikan kerugian dan jejak keuntungan pada masa yang sama.

Julat masa ujian belakang adalah dari Januari 2022 hingga Oktober 2022. Tempoh garis K adalah 15 minit dan model harga penutupan digunakan untuk ujian belakang. Pasaran memilih kontrak kekal Binance ETH_USDT. Parameter ditetapkan mengikut 50 tempoh garis pantas dan 200 tempoh garis perlahan dalam video sumber. Parameter lain tetap tidak berubah secara lalai. Saya menetapkan titik stop loss dan penjejakan titik stop profit kepada 30 mata secara subjektif.
Hasil backtesting adalah biasa, dan nampaknya parameter stop-loss mempunyai beberapa pengaruh terhadap hasil backtesting. Saya merasakan bahawa aspek ini masih perlu dioptimumkan dan direka. Walau bagaimanapun, selepas isyarat strategik mencetuskan perdagangan, kadar kemenangan masih OK.
Mari kita cuba kontrak kekal BTC_USDT yang berbeza:
Hasil backtest pada BTC juga sangat menguntungkan:

Nampaknya kaedah perdagangan ini agak boleh dipercayai untuk memahami trend, anda boleh terus mengoptimumkan reka bentuk mengikut idea ini. Dalam artikel ini, kita tidak hanya belajar tentang idea strategi purata bergerak berganda, tetapi juga belajar bagaimana memproses dan mempelajari strategi veteran di YouTube. OK, kod strategi di atas hanya bata dan mortar saya, hasil backtest tidak mewakili hasil bot sebenar tertentu, kod strategi, reka bentuk hanya untuk rujukan.
