Ara, if i understand you correctly then you need to use StaticVariables.
I use one called "IsInitialized", like below. Here i initialize
Staticvariables only once at the AB startup or first run of the code.
Instead of Static variables you can initialize standard afl variables
between the curly brackets. Just remember to keep the last one that sets
IsInitialized to one.
take care,
herman
GlobalReset = Param("GlobalReset",0,0,1,1);
if( IsEmpty(StaticVarGet("IsInitialized")) OR GlobalReset )
{
StaticVarSetText("TickString","");
StaticVarSet("LastTickPrice",LastValue(C));
StaticVarSet("LastBarNum",BarCount);
StaticVarSet("DownTicks",0);
StaticVarSet("UpTicks", 0);
StaticVarSet("SecondTimer", GetSecondNum());
StaticVarSet("NumTicks",0);
StaticVarSet("IsInitialized",1);
}

Subject: Re: [amibroker] Variables not initialized
Herman,
I also initialize my variable to 0 ..... but I don't want to do it the
"normal" way ...
if I initialize to Null, (or anthing else) then AB will initialize to
Null
for every time the code executes.
Last_BuyState = Null;
IsNull(Last_BuyState) ... the result will always be True.
I am trying to have a scheme where I set variables only once when AB is
first turned on
if (IsNull(Last_BuyState)
{
//initialize variable
Last_BuyState = Null;
}
... else no action
Any way of working that?
Ara
