Strategi ini dinamakan Trend Following Strategy Based on Triple EMA and Linear Regression. Ia menggunakan persilangan purata bergerak eksponensial berganda dan garis regresi linear untuk mengenal pasti arah trend, dan menetapkan stop loss adaptif untuk mengunci keuntungan.

EMA tiga (TEMA) menggabungkan kekuatan EMA tunggal dan EMA berganda untuk menangkap perubahan trend harga dengan lebih sensitif. Garis regresi linear mencerminkan trend keseimbangan harga jangka panjang. Apabila TEMA jangka pendek melintasi di atas garis regresi linear jangka panjang, ia menandakan trend menaik untuk mempertimbangkan perdagangan panjang. Sebaliknya menunjukkan trend menurun untuk mempertimbangkan pendek.

Selepas memasuki, strategi ini menggunakan mekanisme stop loss adaptif berasaskan ATR untuk mengunci keuntungan. Ia menetapkan dan menyesuaikan jarak berhenti berdasarkan turun naik pasaran. Ini mengelakkan berhenti tetap sambil membolehkan berhenti menyesuaikan diri dengan turun naik pasaran.

Kelebihan strategi ini adalah gabungan penunjuk mengenal pasti arah trend dengan agak tepat. Kaedah stop loss adaptif juga lebih maju. Tetapi parameter memerlukan ujian dan pengoptimuman yang berhati-hati untuk produk tertentu, sentiasa menyesuaikan diri dengan perubahan pasaran.

Ringkasnya, integrasi yang munasabah dari pelbagai penunjuk teknikal, bersama dengan langkah pengurusan risiko yang ketat, boleh meningkatkan kecekapan perdagangan strategi dan keupayaan untuk mengurangkan risiko.
