External int changes into -570425344 (No calculations or whatever)

I have defined it as 30. But it shows that mumbo jumbo in the log. This is before any calculations whatsoever, it just goes from 30 to -570blahblah on it's own.

Can you include the code up until that point? Then I can see if it happens when I run it as well.

Running it in strategy tester. If I redefine the variable back to 30 right before it works fine, then it reverts back to -570whatever if I change it back.

Why do you post the ex4 instead of mq4 ?

Like fxtr51 pointed out, need the mq4 or code snippet to be able to check it.

Thanks for the replies.
Today is a really bad day. I rewrote the problematic part, and luckily(unluckily?) I'm getting the same problem.

You are multiplying ADR by 24 each time it reaches ADR * 24. Use two separate variables so it would read like:

iADR = ADR * 24;
double hma = iMA(pair,PERIOD_H1,iADR,0,MODE_SMA,PRICE_HIGH,0);

I think the -5xxxxxxxxxx number is simply that you have exceeded the number that the integer can hold.

To be a bit more specific, have the line read:

int iADR = ADR * 24;

and then

double hma = iMA(pair,PERIOD_H1,iADR,0,MODE_SMA,PRICE_HIGH,0);

and so on.

Oh...
I thought that was only needed in loops.
So how exactly does it keep multiplying it?

I hope this is only the rarely the case because I have alot of code to change then...

Thanks alot because I never wouldve gotten a clue.

Since you have declared ADR as an external variable (outside the start() function) it will retain its value each time the start() function runs, which is every tick. So on the first tick, ADR starts with a value of 30. When start() is run, ADR is assigned the value of 30 * 24 = 720. On the next tick, ADR will start with a value of 720, which then gets multiplied by 24 and so on for each tick.

If you declare a variable inside a function, like init(), start() or any function you create yourself, it can not be accessed by any other function and the variable is removed when the function has finished.

You have declared variables such as "hma" inside the start() function, so when the start function begins they don't exist and they are removed when start() is finished.

So if you use my example of

int iADR = ADR *24;

iADR gets created and deleted each time start() is run, i.e. on every tick while ADR keeps its value of 30 since you are not assigning it any other value in your code.

Ah that makes sense. Of course the part outside start doesn't get ran again and as such the variable doesn't get redefined as 30 again.
