I've been programming indicators for so many months that I'm a little deficient in experts but I'm intending to solve that. Along the way I need a little help. In my expert that I threw together I have it check at bar close if there is a condition that would warrant closing the trade.
I start with a global variable,
datetime PreviousBar; // record candle/bar time[/CODE]
and set one bool in init()
{
do_this = true;
}
[/CODE]
blah blah boring stuff.... etc, etc
then in the main loop I have:
[CODE]
if(do_this == true)
{
PreviousBar = Time[0];
do_this= false; // so it does this only once only
}
if(NewBar() == true)
{
if(TotalOpenOrders() == blah blah close my order you crazy monkey)
}
and outside the main loop I have:
[CODE]//--- returns true if current bar just formed
bool NewBar()
{
if(PreviousBar<Time[0])
{
PreviousBar = Time[0];
return(true);
}
else
{
return(false);
}
return(false);
}OK so it is setup to do once per bar. What I want to do is have a function that increments 90 seconds or 60 seconds or whatever, then sets a bool to true after it's incremented that time. Basically I want to check the indicators every 60, 90, 120 seconds or whatever instead of at bar close. How do I do that?
Thanks for any help,

- nittany1This should do it. Remember that MT uses tick-based execution so per-second-accuracy is not possible (unless you loop everything in the Init() sub.).
if (CallIndicatorsCheck())
{
// your code here
}
bool CallIndicatorsCheck()
{
static datetime Oldtime;
int Secs = 90;
bool Flag;
if (CurrTime() >= Oldtime) {
Oldtime = CurrTime() + Secs;
Flag = true; }
return(Flag);
}
Comment placement
Could someone show me the code to place a comment in theUPPER RIGHTcorner of the screen, rather than the default upper left?
Thanks!

You can't. From MQL4 manual:
If you need by death you could could create objects.

LinusGuy is right; there's no direct way. The easy workaround is to pad your Comment with spaces --
Comment(" hello world!");
willl offset the text to the right.
You can also put in line feeds to drop down the page.
Comment("\n\n\n\n\nyour text");
or combine linefeeds and space to print at the lower right-hand corner of the screen.

no new trade for X bars after a losing trade
hi team - hoping someone can help please..
how do i stop a new trade from commencing for 10 bars if the last trade was a loss?
cheers
The function below will return true while the account history has a loss trade that closed at or after the opening of the 10:th past bar (current bar is 0),
and return false otherwise.
{
datetime since = Time[ bar+10 ];
for ( int i = OrdersHistoryTotal() - 1; i >= 0; i-- ) {
if ( ! OrderSelect( i, SELECT_BY_POS, MODE_HISTORY )
continue;
if ( OrderProfit() = since )
return( true );
}
return( false );
}
[/PHP]
If you add that function to your EA, then include a statement like the following in the start() function, then Bob's your uncle.
[PHP]if ( postMortem() ) return( 0 );thx very much for that - i will try it

guys, do you have the same problem?
I have coded an expert. I want to open a position when the price is the same that one indicator. To do this i use the following sentence:
//to buy
double indicatorpast = icustom(....................,1);
double indicatornow = icustom(....................,0);
if (close[1]indicatornow) OpenBUY();
if (close[1]>indicatorpast && close[0]<indicatornow) OpenSELL();
but with this satatement, the expert opens positions not only when the price cross the indicator, it opens position above the indicator too. I want that the expert open position ONLY when it cross the indicator, so i tried that:
//to buy
double indicatorpast = icustom(....................,1);
double indicatornow = icustom(....................,0);
if (close[1]<indicatorpast && close[0]==indicatornow) OpenBUY();
if (close[1]>indicatorpast && close[0]==indicatornow) OpenSELL();
But this statement it is not performing.
Do you know what is happen? Because i think there arent errors in the statement.
Regards.
