Strategi ini menggunakan algoritma pembelajaran mesin K-Nearest Neighbors (KNN) untuk memprediksi tren harga. Dengan memilih metode perhitungan harga yang berbeda (seperti HL2, VWAP, SMA, dll) sebagai nilai input dan berbagai nilai target (seperti price action, VWAP, volatility, dll) untuk evaluasi, algoritma KNN mengidentifikasi titik data historis K yang paling dekat dengan keadaan pasar saat ini. Strategi kemudian membuat prediksi tren panjang atau pendek berdasarkan arah tren dari titik data K ini. Selain itu, strategi menerapkan rata-rata bergerak untuk meluruskan hasil prediksi dan meningkatkan stabilitas. Akhirnya, keputusan perdagangan dibuat sesuai dengan hasil prediksi, dan perubahan tren pasar saat ini secara visual ditunjukkan melalui perubahan tren di latar belakang warna.
Dengan menerapkan algoritma pembelajaran mesin KNN untuk prediksi tren harga, strategi ini menunjukkan cara menangkap tren pasar dan menghasilkan sinyal perdagangan menggunakan data historis dan metode statistik. Kekuatan strategi terletak pada kemampuan beradaptasi dan fleksibilitasnya, karena dapat dioptimalkan melalui penyesuaian parameter agar sesuai dengan kondisi pasar yang berbeda. Namun, risiko strategi ini terutama berasal dari kualitas dan representasi data historis, serta masuk akalnya pengaturan parameter. Peningkatan di masa depan dapat melibatkan penggabungan lebih banyak indikator, mekanisme adaptif, dan langkah-langkah manajemen risiko untuk lebih meningkatkan ketahanan dan profitabilitas strategi.
