Programming Questions

I know a code in simpler syntax and I am new to the Forex (about a month)

I am trying to make revisions to an EA and thus going line by line to understand the Forex logic (and syntax) with certain sections... this is a section that I am trying to understand as I want to make sure that the code doesn't open orders on Friday, but if trades are still open going into Friday to allow it to manage them without closing them

Thanks so much for your help!
=========================

Variables:

int OpenOrders=0, cnt=0;
extern bool TradeOnFriday=False;
int OrdersTimeAlive=0; // in seconds
bool ContinueOpening=True;
datetime LastOrderOpenTime=0;

================================
Code Block:

// if dont trade at fridays then we close all
if (!TradeOnFriday && DayOfWeek()==5)
{
PreviousOpenOrders=OpenOrders+1;
ContinueOpening=False;
text = text +"\nClosing all orders and stop trading because TradeOnFriday protection.";
Print("Closing all orders and stop trading because TradeOnFriday protection.");
}

// Orders Time alive protection
if (OrdersTimeAlive>0 && CurTime() - LastOrderOpenTime>OrdersTimeAlive)
{
PreviousOpenOrders=OpenOrders+1;
ContinueOpening=False;
text = text + "\nClosing all orders because OrdersTimeAlive protection.";
Print("Closing all orders because OrdersTimeAlive protection.");
}

======================================

Also, what is the purpose of void here?

====================================

void DeleteAllObjects()
{
int obj_total=ObjectsTotal();
string name;
for(int i=0;i<obj_total;i++)
{
name=ObjectName(i);
if (name!="")
ObjectDelete(name);
}
ObjectDelete("FLP_txt");
ObjectDelete("P_txt");
}

Are there any programmers that can spend 10-15 min on a chat with me to give me direction so I can properly edit an EA?

I found a function for broker digits... there is a set of templates with this EA that also needs the broker multiplying ratio to it, but I don't know how to call that into a template file because the .tpl file looks like it is all text and it isn't doing any function work

I changed this:

OrderSend(Symbol(),OP_SELL,mylotsi,SellPrice,slippage,sl,tp,"MyMEFx EA"+MagicNumber,MagicNumber,0,ArrowsColor);
return(0);

To:

int ticket = OrderSend(Symbol(),OP_SELL,mylotsi,SellPrice,slippage,0,0,"MyMEFx EA"+MagicNumber,MagicNumber,0,ArrowsColor);
Sleep(1500);
OrderModify(ticket,OrderOpenPrice() ,sl,tp,0,ArrowsColor);

=========================================

I am getting these errors:

2009.02.28 17:32:59 2009.01.01 20:42 EATest AUDJPY,H1: invalid ticket for OrderModify function
2009.02.28 17:32:59 2009.01.01 20:42 EATest AUDJPY,H1: OrderSend error 131

Here is a list of runtime errors in MQL4.

You can do a search on the MQL4 articles, codebase and/or forum, you'll probably find out answers to your question.

void indicates that the function returns no data. this can be void, int, double, bool for example it just depends on what sort of data is returned.

Better to use TimeDayOfWeek instead if you plan on running the EA through the strategy tester. Dayofweek will only return the current day of the week even in the strategy tester.

Well, thanks to Ronald, I was able to fix the Market Execution so now I understand how to do it with all EAs now Where does the print function print to? I am getting SendError 131 which is a lot size issue related to my broker.... if I put it in the function to print lot size, where is that data going to? I am familiar with msgbox function on vba when I want to see a variable value pop up during execution Right now, this EA is closing everything on Friday.... I will work to fix that next... why do you suggest the change from DayofWeek==5 to TimeDayofWeek==5? Can you explain to me the logic behind it? Right now it is checking to see if it is Friday and closing all trades... when I do the edit, I will want it to check to see if it is Friday and not open any new ones, and maybe certain rules on how to manage the ones that are still open going into Friday
