Vladimir Fionov:
YES

if(counted == 0) limit-=1+Par1;

Instead of what I advised in the previous post, change to this line, it might work.

What is the error? I can not understand not much. I have output the strings for the condition also outputs itself. It's not about the condition above.

Solved!

Can anyone explain why this was the case?

The operator ends with a semicolon. (;)

Oh yes, thanks. I can't see the trivial stuff under my nose.

Wrote a system, it uses let's say 2 price levels (b8 and s8) to open positions which I save in variables like fractional, and in case the terminal restarts it loses these values I set Alert.

 if((в рынке ордеров>0 && (b8==0||s8==0))==false)

{

}

else Alert("Error");

Zero values are only set when there are 0 orders in the market. I checked in the test all is normal all is working, put on a real, and now has passed about a day -/+ 20 minutes and it starts to spit Alert (for a day it has opened 1 order and it was open).

What is the problem? Maybe in the lifetime of the variable?

You need to compare variables with type double via NormalizeDouble()

[Leanid Aladzyeu]

Yury Reshetov:
Use NormalizeDouble() to compare variables of type double

0 is not a double type

[Yury Reshetov]

Leanid Aladzyeu:
0 is not a double type.

And this crap, what type:

Leanid Aladzyeu:
... 2 price levels (b8 and s8)

and why is it compared to zero?

Yury Reshetov:

And this shit, of what type:

It clearly and explicitly says, "into a variable of the fractional type" :)))

You could get spit onby Alert for such questions :))

[Leanid Aladzyeu]

Yury Reshetov:

And this stuff, what kind of stuff:

and why does it compare to zero?

0 is for the notion of whether these levels are lost in case of loss the variables will equal 0 .
