Belajar Coding EA (mql) asas

[aiman]

UseStopLoss diguna pakai ketika nak entry aje untuk dapatkan StopLossLevel pada OrderSend, kalau price hit SL, post akan tertutup sendiri (bukan EA yang tutup), sebab SL dah di pasang ketika open post, SL ni EA dah tak monitor lagi. Kalau tutup pc pun post tetap akan tertutup sendiri kalau kena SL.

oo..jd sl dalam ea ni tak berkait dgn closebuy/sell lah kkan..ini bermaksud kalau kita set sl, bila closebuy/sell trigger dulu, post still akan close jugak kan....ok tq bro

Bro..

Nk tanye la kalau situasi cam ni..

Bila kita ada EA..

kalau line broker tk brape cantik la (re quote masa nk buat BUY/SELL/CLOSE)..

ape cadangan yg terbaik..?

nk repeat buy 5 kali ke..?

sleep(5000);

kalau masih tk dapat close gk cam ne..?

 

[aiman]

biasanya saya buat repeat, dalam repeat letak Sleep jugak.
Kalau tak jalan jugak, tak boleh buat apa dah, tu broker yang problem. Kalau terjadi kat manual pun tak boleh buat apa2.

masta aiman ..betul ke sleep(5000) letak kat sini? saya hantam saja ni... kalau saya nak letak utk close nak letak kat man lak masta

 

[aiman]

code saya macam ni. Percubaan OrderSend maksimum 10 kali
diselang-seli Sleep(500); Kalau gagal (requote) dia try lagi.... sampai 10 kali. Tapi kalau berjaya sebelum 10 kali, dia stop.

bool retry=true;
int count=0;

while (retry)
{    
   if (OrderSend(Symbol(),OP_BUY,1,Ask,3,0,0,"",0,0,Green)>0) retry= false;
   if (retry) 
   {
      Sleep (500);
      count++;
      if (count>=10) retry= false;
   }
}

Sleep(500); bermaksud EA akan tido setengah saat, baru dia cuba lagi sekali. Kalu 1 saat Sleep(1000); kalau Sleep(5000); bermaksud 5 saat. Pada saya 5 saat tu lama sangat.

masta...repeat tu code dia sleep(5000); ke? cth kalau ea close ma10 cross ma25...katakan masa cross tu requote..lepas tu cross tu dah terlepas..kalau saya gunakan sleep(5000) ni di akan ulang sehingga close walaupun cross dah terlepas ke?..

kat mana nak attach sleep(5000) dalam ea tu? mintak tolong masta..
