Strategi ini adalah sistem trend berikut adaptif berdasarkan pelbagai penapis penunjuk teknikal. Ia menggabungkan pelbagai penunjuk teknikal termasuk Exponential Moving Average (EMA), Simple Moving Average (SMA), dan Moving Average Convergence Divergence (MACD), menyesuaikan parameter secara dinamik untuk menyesuaikan diri dengan persekitaran pasaran yang berbeza untuk menangkap trend yang cekap dan kawalan risiko. Strategi ini menggunakan mekanisme penapisan berlapis-lapis, yang meningkatkan kebolehpercayaan isyarat perdagangan dengan ketara melalui gabungan sinergi pelbagai penunjuk teknikal.
Logik teras adalah berdasarkan mekanisme penapisan tiga lapisan:
Generasi isyarat perdagangan memerlukan semua syarat penapis dipenuhi: peralihan trend, pengesahan arah SMA, dan sokongan garis isyarat MACD. Strategi ini juga merangkumi sistem pengurusan kedudukan dinamik berdasarkan ekuiti akaun, menyesuaikan saiz kedudukan secara automatik melalui faktor leverage.
Strategi ini mencapai trend yang agak boleh dipercayai melalui mekanisme penapisan pelbagai lapisan dan pelarasan parameter dinamik. Walaupun terdapat beberapa risiko kelewatan dan pergantungan parameter, prestasi yang stabil masih dapat dicapai dalam perdagangan sebenar melalui pengoptimuman parameter yang munasabah dan langkah kawalan risiko.
