Default static classType

Hi

I need to re_instantiate the object if a condition is met inside the OnCalculate.

Will the following be the BEST way?

many thx

MQL5 Code:
int OnCalculate(...

static ClassType var_name1(_Symbol, _Period);  
int x = 1;
if(x) var_name1 = new ClassType var_name2(_Symbol, _Period);

Not sure, sorry. Why would you need that?

to reduce the overhead.

How many times will the constructor be called in the following code?

MQL5 Code:
int OnCalculate(...

static ClassType var_name1(_Symbol, _Period);

Should only once, but that's easy to check - just put some Print function into the constructor.
