Baru-baru ini, pengguna platform sangat berharap dapat memindahkan strategi bahasa Maya ke strategi JavaScript, sehingga dapat dengan fleksibel menambahkan banyak ide optimasi; bahkan memperluas strategi ke berbagai versi. Karena strategi bahasa Maya biasanya merupakan strategi tren, dan banyak yang dilakukan dengan model harga tutup.
TR:=MAX(MAX((H-L),ABS(REF(C,1)-H)),ABS(REF(C,1)-L));
ATR:=EMA(TR,LENGTH2);
MIDLINE^^EMA((H + L + C)/3,LENGTH1);
UPBAND^^MIDLINE + N*ATR;
DOWNBAND^^MIDLINE - N*ATR;
BKVOL=0 AND C>=UPBAND AND REF(C,1)<REF(UPBAND,1),BPK;
SKVOL=0 AND C<=DOWNBAND AND REF(C,1)>REF(DOWNBAND,1),SPK;
BKVOL>0 AND C<=MIDLINE,SP(BKVOL);
SKVOL>0 AND C>=MIDLINE,BP(SKVOL);
// 止损
// stop loss
C>=SKPRICE*(1+SLOSS*0.01),BP;
C<=BKPRICE*(1-SLOSS*0.01),SP;
AUTOFILTER;
Logika trading strategi ini sangat sederhana, pertama-tama menghitung ATR berdasarkan parameter, kemudian menghitung rata-rata harga penutupan tertinggi, terendah, dan terendah dari semua garis K BAR, dan mencari indikator EMA berdasarkan data rata-rata ini. Akhirnya menggabungkan koefisien N dalam parameter ATR. Menghitung downtrack (upBand, downBand).
Pengecualian ini dilakukan pada saat trading. Pengecualian ini dilakukan pada saat trading. Pengecualian ini dilakukan pada saat trading. Ketika harga penutupan mencapai garis tengah, harga penutupan mencapai harga stop loss (sesuai dengan SLOSS stop loss, SLOSS adalah 1 atau 0.01, yaitu 1%)). Strategi ini dilakukan dengan model harga penutupan.
OK, setelah memahami kebutuhan strategi dan ide-ide bahasa Melayu, maka kita bisa melakukan transplantasi.
