Quick MQL4 problem: ordernumbers

I can't figure out why this happens, any help will be appreciated:

I open a new buy_stop order and store the ticket nr in : int LongOrderNr

The following alert shows my the correct order nr.

Alert("New long order ticket : "+LongOrderNr);

On the next tick I try to select the order with the LongOrderNr but my LongOrderNr value is now 0 (zero) and not the ticket nr anymore???

Is LongOrderNr a global variable? If it's a local variable, it will be set to zero on each incoming tick because local variables only valid for the given call.

You need to declare the variable globally)ie before the start() function, or you must make it a static int.

Each time you run a function, it starts the variable from new, unless they are brought in from outside the function, either globally, or via reference or have been explicitly told to remember the variable ie static.

hey pas...... sounds like you might be declaring the int LongOrderNr inside the start function or possibly a function being called from inside the start function.....

sometimes things need to be declared first, outside the start()...... or possibly define it as last ticket number.......

int LongOrderNr = GetLastLongTicket(); ........h

i see kenny beat me again........

my 2 words per minute typing just can't compete...........h

Thanks to all you guys, much appreciated!

What would the best option be between a global variable or static variable?

Global variables are accessable from anywhere. Local static variables only in the local scope of the function.
I prefere globals for that - it doesn't really matter.
