Does restarting MT4 reset the EA flags?

Does restarting MT4 reset the EA flags and variables to their original declare state i.e. "false" and "0" even with the EA still attached to the chart, or would they be preserved in their most recent state?

When you close MT4, anything with a deint() function is triggered. When you restart MT4, anything with an int() function is triggered. So, no, the variable values will be lost.

Would it work if the flags and variables were declared before deint() and init() ?

If they were stored in GlobalVariables (F3 in MT4), then yes

Are all the variables and flags declaration before the init() considered Global?

For Example:

#define SIGNAL_NONE 0
#define SIGNAL_BUY 1
#define SIGNAL_SELL 2
#define SIGNAL_CLOSEBUY 3
#define SIGNAL_CLOSESELL 4
extern int MagicNumber = 0;
extern bool SignalMail = False;
extern bool EachTickMode = True;
extern double Lots = 0.3;
extern int Slippage = 1000;
extern bool UseStopLoss = False;
extern int StopLoss = 30;
extern bool UseTakeProfit = False;
extern int TakeProfit = 60;
extern bool UseTrailingStop = False;
extern int TrailingStop = 30;
int BarCount;
int Current;
bool TickCheck = False;
bool buyFlag = false, sellFlag = false;
datetime barStart = 0;
double stoploss;
bool InTrade = false;


If any of these were to be changed by the programming logic during the course of running the EA, will their changed states be preserved after restarting MT4 instead of being reset to their original declarations above?

Also, am I right to say that these Global Flags and Variables will only be reset if I remove and reattach the EA?

Are the above variables Global?

Hello I am still waiting for an answer.

Can someone confirm to me whether all variables declared above init() are store under Global Variables F3?

Working with global variables requires that you use the global variables funtions. If you are unsure, just press F3 when you have MT opened and check the list. :nerd:

2 kinds of globals:
1) A bit confusing. Variables defined in the space before the first function are global in scope to the entire module.
2) There are also "Global Function" variables that are defined and placed in a separate space and are kept between shutdown/restarts. These show in the area referenced in the last post.
It's up to the programmer as to how much recovery is built in.
Some items could be written to a text file for re-reading at restart.

Those variables are more properly called static variables with a program scope. What I mean by program is an indicator, script or EA. They are static in that between calls the values don't change like local variables and they have a program scope meaning they are visible to all functions within the program again unlike local variables which are only visible to the function in which they are declared.

Some people call these globals because they learned that from other languages. But in MQL4, there is a special set of variables called global and that is what I prefer to call global. These special globals are visible to all programs as you are probably aware.

How do I declare and/or store my variables into the F3 Global Variables? Can bool flags also be stored there?

Also, how can I stored variables into text file, to be re-read on restart?
