Salam...camn nk buat trailing stop dengan paling berkesan..?

Boleh cari balik kat page belakang ebook tempe.
Sample codes pun ada sekali. Ada code trailing stop dalam tu. Dia dulu buat kelas mengajar EA, sebabtu ada ebook. Free plak tu dia kasi kat sini. Rugi la kalau tak download.


Tak payah pi jauh2, ada kat atas tu

bro..

sye dh try pakai trailing kt dlam ebook tu..

memang jalan ok..order cantik..order modify pn jalan..

tapi ada error 1..

walau ada error tapi still tk loss simulasi strategy tester 2..

ke nk pakai live test..?

 

[aiman]

Kalau tak silap, code tempe tak ada trailingstep, setiap pips bergerak, ea akan cuba ubah SL. Kadang kala tak sampai 1 saat price akan bergerak semula ke belakang sebelum ea sempat ubah SL. Jadi ea cuba modify nilai SL yang sama. Sebabtu dapat error 1. Boleh abaikan error 1 ni.

Refer kat sini maksud error

MINTA BANTUAN ,,,, DI ATAS ADALAH DARI INDI AutoTrendChannel.mq4 YANG DIUBAH PADA NAME LINE BUYSTOP DAN SELLSTOP.

SAYA GUNA INDI TERESEBUT DENGAN EA TRENDLINE

MASAALAHNYA, KEKADANG BUY STOP DAN SELLSTOP TERBALIK.~X(

 

[aiman]

Dah ada 2 price untuk TL buystop dan TL sellstop. senag aje tak perlu susah2 kaji formula lagi.
Hanya perlu check kedua2 price mana lebih tinggi, sekiranya TL buystop di bawah TL sellstop, swap aje price kedua2 TL itu.

  double priceTmp;
  
  if (price_p1>price_p2) // Sekiranya terbalik
  {
   priceTmp=price_p1;  // swap price_p1 dan price_p2
   price_p1=price_p2;
   price_p2=priceTmp;
   
   priceTmp=price_01;  // swap price_01 dan price_02
   price_01=price_02;
   price_02=priceTmp;
