Hello,

if one changes the period of the chart or enters new values to the indicator, than all variables are put back, but if one simply only switches off the terminals and then switch it on again the variables are not put back again?

Who knows the problem and a solution?

Eaxmple:

PHP Code

 
bool first=true;
 
int start() {
 
if(first==true){
   Print("first is true ",TimeToStr(Time[0],TIME_DATE|TIME_MINUTES));
   first=false;
}
 
} 

Now first you get the issue from the Print() function, now you switch down the terminal and after example 2 minutes you switch the terminal on again, and now you dont get a issue from the Print() function again, but if you just change the period or kompiler the script you get a issue again, because the variables are all put back to their onset, but if you switch of the terminal and than switch on again it dont works, because why please?

Hello tesla and thank you for help to,
with "terminal" I mean the whole programm. And with shut down it I mean thus you press the red x above right.

Then if you start the programm again the chart is open again of last where the script/indicator is put. But the Variables dont have change it last values which where before you shut down the programm, you can see at at the example code i have offered above, the value of the variable keeps same.

What I want is that if the terminal is shut down once and then start again that all variables be reset.

If you have your variables declared inside the start() function then after you bring the terminal back online they should be reset as soon as the first tick comes in. HTH

Hello again, I think maybe my explanations are not so understandable, because of that I just want to ask it more simply.

Is there a possibility as one all variables become reset after the terminal is switch off and on again. Like when the chart symbol or timeframe has been changed?

   first=true;

   first=false;
} 

dd=GlobalVariableSet("dl",1.1); 

if(GlobalVariableCheck("dl")==true  ){
  df=1234;
}
GlobalVariablesDeleteAll();

Hello again,

thank you very much tesla for your help!

I think now I have find a solution for me.

In the init() function I declare first a global Variable

PHP Code

dd=GlobalVariableSet("dl",1.1); 

Then in the start() function I check first a expression about the gloabal Varaible and then delete the varaile komplett after the action in the expression block is done.

PHP Code

if(GlobalVariableCheck("dl")==true  ){
  df=1234;
}
GlobalVariablesDeleteAll(); 

The advantage is that the gloabl variable every time when closeing the terminal.exe programm and switch on again is be changeing, but with other varaibles there was the problem that they are not chaning/launched by closing und switching on again the terminal.exe.

Now in my test this solution works like I want and I think and hopes it remains in such a way.

Sadly the mine english is not so good to can explain better, but I will learn.
