question about this code

[[Deleted]]

good day, peeps.

i've just read about mql4. now, i have a question about a code that i got from this site (https://www.mql5.com/en/articles/1481). it's about the martingale system. although i dont intend to use it in live account, i just want to practice with it.

here's the code:

extern int distance=30;

int init()
{
//----
MathSrand(LocalTime());
//----
return(0);

int err = 0;
double Lot = 0.1;
double Ballance=0.0;
int start()
{
//----
if (OrdersTotal()==0&&err==0)
{
if (Ballance!=0.0)
{
if (Ballance>AccountBalance())
Lot=2*Lot;
else
Lot=0.1;
}
Ballance=AccountBalance();

int order;
if (MathRand()%2==0)
order=OrderSend(Symbol(),OP_BUY,Lot,Ask,5*Point,Bid-distance*Point,Ask+distance*Point);
else
order=OrderSend(Symbol(),OP_SELL,Lot,Bid,5*Point,Ask+distance*Point,Bid-distance*Point);



if(order<0)
{
if (GetLastError()==134)
{
err=1;
Print("NOT ENOGUGHT MONEY!!");
}
return (-1);
}
//n++;

}


//----
return(0);
}

why is it when i run this code, i get error code 130? i didn't change anything in this code... i just copied and paste it.

thanks in advance.

u could use search box at top right of every page.

130 gives hits into documentation - read and then can learn more about wat mql4 + Client Terminal doing.

is fun if hang in there

oh yes... if new - have you take time read MQL4 Book

lots info on placing orders - u will see reasons why u getting 130

btw, code on site is public and so is not to be seen as valid - imho
