ExpertsDllConfirm in start.ini seems not to work
Hi,
The ExpertsDllConfirm in start.ini seems not to work:
ExpertsDllConfirm=false doesn't make this flag reset at start up. See attached options dialog window. Can anyone else confirm this is a bug for MT4? Is there a workaround for this?
Thanks,
Jeff

JeffHi
maybe not a bug, check if don't have some files set RO. By only click out the option should be enough
Also, there is no start.ini file.
Hi

Also, there is no start.ini file.Of course, the MT4 can be started with start.ini like this command:
terminal config\start.ini
This file contains a list of settings to login an account, to select chart, to switch options, etc... See MT4 manual for more info about this (Tools - Configuration at startup). It's only that ExpertsDllConfirm=false seems not to work...

Also EnableDDE and EnableNews does not work.
Hi all,
How can I get the higher/lower price for a symbol between 2 specific times?
Example: I want to get the EURUSD higher price between the 1.1.2008 00:00 until the 1.2.2008 00:00.
How can I do that ?
Thanks !Something like this:
string date1 = "2008.01.01 00:00";
string date2 = "2008.01.02 00:00";
string sym = "YourSymbol";
datetime t1 = StrToTime(date1);
datetime t2 = StrToTime(date2);
int b1 = iBarShift(sym, PERIOD_M1, t1, false);
int b2 = iBarShift(sym PERIOD_M1, t2, false);
//Assuming that date1 < date2
double HH = iHigh(sym, PERIOD_M1, iHighest(sym, PERIOD_M1, MODE_HIGH, b1-b2+1, b2));
double LL = iLow(sym, PERIOD_M1, iLowest(sym, PERIOD_M1, MODE_LOW, b1-b2+1, b2));
Returning the # of orders on a certain chart
How do you
Return the # of orders on a certain chart?

//------------------------------------------------------------+Timelimit on orders
Hello,
I am in the process of programming an EA and trying to place a time limit on orders. For example, if a trade is opened on the first of the month I would like to force it to close if the parameters on my EA are not reached by the fifth day or so. I have tried to search the forum, but with so many results with the terms "time limit" I have failed to find an answer.
Thanks for your help!

Thanks for your help!Calculate how many seconds are 5 days, add it to "OrderOpenTime()" compare it to "TimeCurrent()".
Hope this helps
