Since your call is bogus, nothing happens and your array has zero size. You would know that if you had bothered to check your return codes, and report your errors (including market prices and your variables). Don't look at GLE/LE unless you have an error. Don't just silence the compiler (MT5/MT4+strict), it is trying to help you.Your code Documentation CopyTime( Time, _Period, 0, 999999, myTime );
int CopyTime( string symbol_name, // symbol name ENUM_TIMEFRAMES timeframe, // period int start_pos, // start position int count, // data count to copy datetime time_array[] // target array to copy open times );

Was trying to write a signal trigger alert that only appear once but not sure what it keeps pop out "array out of range" in my code. Anyone can help on this?
#include <Trade\Trade.mqh>
CTrade trade;
datetime LastActiontime;
void OnTick()
{
double Ask = NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits);
double Bid = NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_BID),_Digits);
datetime myTime[];
double myRSIArray[];
ArraySetAsSeries(myRSIArray,true);
ArrayResize(myTime,100000,100000);
int myRSIDefinition = iRSI(_Symbol,_Period,14,PRICE_CLOSE);
datetime Time = iTime(_Symbol,_Period,0);
CopyBuffer(myRSIDefinition,0,0,3,myRSIArray);
CopyTime(Time,_Period,0,999999,myTime);
double myRSIValue0=NormalizeDouble(myRSIArray[0],2);
double myRSIValue1=NormalizeDouble(myRSIArray[1],2);
double myRSIValue2=NormalizeDouble(myRSIArray[2],2);
if(myRSIValue1>=70 && myRSIValue2<70
&& LastActiontime!=myTime[0]
){
Alert("RSI cross-up 70"+" "+_Symbol);
LastActiontime=myTime[0];
}
if(myRSIValue1<70 && myRSIValue2>=70
&& LastActiontime!=myTime[0]
){
Alert("RSI cross-down 70"+" "+_Symbol);
LastActiontime=myTime[0];
}
if(myRSIValue1<=30 && myRSIValue2>30
&& LastActiontime!=myTime[0]
){
Alert("RSI cross-down 30"+" "+_Symbol);
LastActiontime=myTime[0];
}
if(myRSIValue1>30 && myRSIValue2<=30
&& LastActiontime!=myTime[0]
){
Alert("RSI cross-up 30"+" "+_Symbol);
LastActiontime=myTime[0];
}
}
