Ringkasan

Strategi ini menggunakan penunjuk Coral Trend LazyBear untuk menentukan arah trend harga dengan mengenal pasti pembalikan penunjuk Coral Trend untuk mengesan titik kemasukan yang berpotensi. Untuk menapis pecah palsu, strategi ini menggunakan penunjuk ADX atau gabungan histogram kekuatan mutlak dan penunjuk Jilid HawkEye sebagai penunjuk pengesahan untuk kemasukan yang lebih boleh dipercayai.

Mekanisme keluar menggunakan harga tertinggi / terendah dari N lilin yang paling baru dikalikan dengan nisbah risiko-balasan yang boleh dikonfigurasikan untuk menetapkan stop loss dan mengambil keuntungan.

Logika Strategi

Selepas menentukan arah trend utama berdasarkan penunjuk Coral Trend, apabila warna penunjuk tetap tidak berubah, dan harga menunjukkan penurunan kecil ke arah yang bertentangan. Pada masa ini, jika penurunan berakhir dan harga kembali ke arah trend utama yang ditunjukkan oleh Coral Trend, ia boleh dianggap sebagai titik masuk yang baik.

Syarat kemasukan termasuk:

Arah penunjuk Coral Trend adalah selaras dengan arah perdagangan (panjang = hijau, pendek = merah)
Sejak kali terakhir harga sepenuhnya memecahkan penunjuk Coral Trend (titik tinggi bar terakhir melebihi garis Coral Trend), terdapat sekurang-kurangnya 1 bar dengan titik rendah di atas (panjang) atau titik tinggi di bawah (pendek) penunjuk Coral Trend
Satu penurunan kecil berlaku ke arah yang bertentangan, di mana harga penutupan kekal di sisi yang bertentangan dengan Coral Trend
Selepas penurunan berakhir, harga penutupan kembali ke arah trend utama yang ditunjukkan oleh Coral Trend

Di atas adalah syarat utama. Pada masa yang sama, strategi mengamalkan penunjuk ADX atau Histogram Kekuatan Absolut dan penunjuk Jarak HawkEye sebagai syarat pengesahan untuk kemasukan.

Indikator ADX memerlukan nilainya > 20 dan meningkat lebih daripada 1 bar terakhir. Dan urutan garis hijau dan merah DI adalah konsisten dengan arah perdagangan.

Histogram Kekuatan Mutlak memerlukan warnanya konsisten dengan arah perdagangan (panjang=biru, pendek=merah).

Mekanisme keluar menggunakan harga tertinggi / terendah dari N lilin yang paling baru dikalikan dengan nisbah risiko-balasan untuk menetapkan stop loss dan mengambil keuntungan. Nilai N dan nisbah risiko-balasan boleh dikonfigurasi melalui parameter.

Analisis Kelebihan

Kelebihan terbesar strategi ini ialah selepas menentukan arah trend utama menggunakan penunjuk Coral Trend, ia mengesan peluang kemasukan dengan mengenal pasti pembalikan, mengelakkan hanyut di pasaran yang tidak trend.

Di samping itu, strategi ini menyediakan mekanisme kawalan risiko yang lengkap, termasuk menetapkan besar stop loss dan mengawal peratusan pendedahan risiko, supaya walaupun perdagangan individu kehilangan wang, ia tidak akan menyebabkan kesan besar terhadap jumlah modal.

Analisis Risiko

Risiko terbesar dari strategi ini adalah bahawa penggunaan penunjuk untuk penilaian kemasukan dapat dengan mudah mewujudkan ilusi, percaya bahawa anda boleh membuat wang secara automatik hanya dengan bergantung pada konfigurasi parameter. Sebenarnya, kedua-dua pengoptimuman parameter dan konfigurasi peraturan perlu digabungkan dengan undang-undang perubahan harga yang mendasari, secara intuitif menilai kesan penunjuk dan harga, untuk menetapkan konfigurasi yang lebih sesuai dengan gaya perdagangan dan produk anda sendiri.

Di samping itu, penetapan stop loss dan mengambil keuntungan juga perlu sesuai. Ganda mengambil keuntungan yang terlalu besar boleh mengakibatkan kegagalan mengambil keuntungan, sementara stop loss yang terlalu kecil akan mengakibatkan risiko yang berlebihan. Ini perlu ditetapkan mengikut turun naik produk yang berbeza dan toleransi risiko peribadi.

Arahan pengoptimuman

Arah optimum strategi ini termasuk:

Penyesuaian parameter penunjuk Coral Trend untuk menjadikannya lebih sensitif terhadap perubahan harga produk yang berbeza
Cuba penunjuk atau kombinasi penunjuk yang berbeza, seperti KDJ, MACD, dan lain-lain, untuk membuat isyarat kemasukan lebih tepat
Mengikut turun naik produk yang berbeza, sesuaikan kaedah pengiraan stop loss dan mengambil keuntungan untuk mencapai kawalan risiko yang lebih baik
Tambah modul pengurusan dana untuk menyesuaikan kuantiti pesanan tunggal berdasarkan bilangan kedudukan yang dipegang, dengan berkesan mengawal kerugian keseluruhan
Tambah modul kawalan masa dagangan untuk membuat strategi hanya berjalan semasa tempoh tertentu untuk mengelakkan kerugian semasa tempoh turun naik yang melampau

Kesimpulan

Strategi ini mula-mula menggunakan Coral Trend untuk menentukan trend harga jangka menengah dan panjang, kemudian dengan menilai pembalikan, digabungkan dengan isyarat mengesahkan untuk menapis keluar pecah palsu, ia membina trend yang agak boleh dipercayai mengikuti strategi. Pada masa yang sama, tetapan kawalan risiko yang lebih baik juga membolehkan strategi ini berjalan untuk masa yang lama dengan modal yang stabil. Dengan pengoptimuman lebih lanjut parameter dan modul, strategi ini dijangka menyesuaikan diri dengan lebih banyak produk dan mempunyai kestabilan dan keuntungan yang lebih baik.
