Strategi ini adalah sistem perdagangan pelacakan tren berdasarkan Gaussian Ripple dan StochRSI. Strategi ini mengidentifikasi tren pasar melalui saluran Gaussian dan menggabungkan zona overbought dan oversold dari indikator StochRSI untuk mengoptimalkan waktu masuk.
Inti dari strategi ini adalah saluran harga yang dibangun berdasarkan algoritma Gosnell Wave. Implementasi spesifik mencakup beberapa langkah kunci berikut:
Strategi ini, melalui kombinasi dari Gaussian dan StochRSI, memungkinkan pelacakan tren pasar secara efektif. Sistem ini memiliki kemampuan pengurangan kebisingan dan kemampuan untuk mengenali tren yang baik, tetapi ada juga keterbelakangan dan kesulitan dalam pengoptimalan parameter. Dengan terus-menerus mengoptimalkan dan menyempurnakan, strategi ini diharapkan untuk menghasilkan keuntungan yang stabil dalam perdagangan nyata.
