Get High - Low between a timeframe

I need some help to calculate the High and the low price of a pair, between a specfied timeframe, like the order open time and current time. It's this possbile?

Sure - ArrayMaximum and ArrayMinimum are the best way I have found.

int nbarsOpen = iBarShift(NULL, 0, orderOpenTime);
double hi = High[ArrayMaximum(High, nbarsOpen, 0)];
double lo = Low[ArrayMinimum(Low, nbarsOpen, 0)];

CodeMeister gave you a solution, another solution is to work with a "for" cycle

double max=0, min=1000;
for (int i=n;i>=0;i--) //n is the number of the bar you want to start from
{
if(High[i]>max) max = High[i];
if(Low[i]<min) min = Low[i];
}

to find the number of a specified time, in your case order open time:
the order should be already selected, to do this, when you open an order do like this: ticket = OrderSend(...);
and then OrderSelect(ticket, SELECT_BY_TICKET);

datetime t1;
t1 = OrderOpenPrice();
for(i=0;i>=100000;i++)
{
if(Time[i] == t1) n = i;
}

so here's the whole code

this code is not "optimized" anyway

Tried the CodeMeister code and it works and is much simplier and I think much faster, then entering in a loop. Also, I see that it only displays 4-Digit prices, even I'm on a 5-Digit platform. Also, if I want to calculate from OrderOpenTime() and OrderCloseTime() ? Thanks again

int nbarsOpen = iBarShift(NULL, 0, orderOpenTime);
int nbarsClose = iBarShift(NULL, 0, orderCloseTime);

double hi = High[ArrayMaximum(High, nbarsOpen-nbarsClose, nbarsClose)];
double lo = Low[ArrayMinimum(Low, nbarsOpen-nbarsClose, nbarsClose)];

nbarsOpen-nbarsClose is because the second parameter of the function is simply the amount of elements to search in, the third parameter is the starting element.

Okay, thanks to clarify. Sorry for being so 'dumb' with my questions, but how can I get it to show a 5-Digit price? Thanks

Fixed it, I used Point to get it right. Thanks

May want to check if it is picking up the right figure when the earliest bar is the highest or lowest. If it is missing that figure, maybe add +1 or -1 to the "amount of elements" in the middle.

But using the ArrayMaximum/Minimum may skip the problem I run into with a range thingy.

How did you add in your Point fix ?

cheers scalpz

I checked it and it's picking up the right bar on open/close. Here is the code:

EDIT: Add a backslash before "n . I don't know why is not showing.
