executing scripts on chart
I assume you are using a demo account, so there should be no issue over the broker allowing EA-initiated orders.
Have you checked that the "Allow Live Trading" box is ticked and that the expert is showing a smily face at the top right of your chart?
If so, then I reckon if you print out the value returned by GetLastError(), you will probably see either:
- an invalid stops error (130), due to the fact that you are trying to execute a buy order and setting the stoploss higher than your entry price
or
- a not enough margin error (134 off the top of my head), if you don't have a leveraged account (as you are attempting to open a full lot)
As you state that you're a programmer, please allow me to slap your wrist for your shameful lack of exception handling. Go stand in the corner! :-)

Hi All,
4 months ago i started to trade with forex using mt4 platform, one thing i don't get
how to executu script on chart.
I spent quite some time working as developer in C# and C++, so i am quite good with coding.
thing is when I drag even the simpliest script on chart, nothing happens, no new order is created nothing.
I found here on this site some script how to make 3 same orders, i will paste it bellow:
#property copyright "Copyright © 2008, PRMQuotes Software Corp."
#include <stdlib.mqh>
#include <WinUser32.mqh>
extern double Lots = 1.0;
int start()
{
OrderSend(Symbol(),OP_BUY,Lots,Ask,3,Ask+16,Ask+36,"refa1",0,0,CLR_NONE);
//OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,0,"refa2",0,0,CLR_NONE);
//OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,0,"refa3",0,0,CLR_NONE);
}
I pasted it in ME compiled it and then it showed up in the mt4 in sidebar.
As i understand this script, when i drag her on the chart, should figure it out which symbol i am dealing with (should it?), and then place the trade as active.
when i drag it to the chart nothing happens. I don't know why.
Should i specify what symbols i am trading inside the script or how does it go.
As i mentioned, i quite good with coding and have really good knowledge in math, aproximations, predictions and so on regarding the functions.
Please help me run and execute first script on mt4 so i can start creating some tools.
p.s.
I didn't manage to run even default scripts that come with mt4, i don't know how i couldn't find it anywhere described. that is why i am posting here.
