RSI array out of range error

[Seleucus]

Hi guys. newbie here ..I need some help. 

I would like to use rsi value of 5th candle as part of my entry so I need to keep checking for it's value . I compiled my code and have no errors or warnings. However when using strategy tester, I keep getting array out of range (89,38) . How can I fix this and make the code work as  intended . 

 Please give advice if I have done it wrong. Here's the code below 

double rsiArray[];
  
   int rsiHandle = iRSI(_Symbol,PERIOD_CURRENT,7,PRICE_CLOSE);
   
   ArraySetAsSeries(rsiArray,true);
  
   CopyBuffer(rsiHandle,0,5,6,rsiArray);
  
   double rsi = NormalizeDouble(rsiArray[5],2);

Additionally, I have used rsi value in this code below below

if((rsi > 80) && (slowMaArray[5] > 12000) && (FastMaArray[0] < slowMaArray[0] && FastMaArray[1] > slowMaArray[1]))
{
  trade.Sell(0.2,_Symbol,0,0,0);
}

If this is the source of the problem or  my if statement is wrong please advise also . (I have a feeling it's wrong lol)

Thanks .

1. Please paste your code correctly: click the  button, then paste your code into the popup window. I have edited your message.

2. You have a gross mistake: you create an indicator handle on each tick. According to the MQL5 style, the indicator handle should be created ONLY ONCE and should be done in OnInit.

See an example of creating a simple Expert Advisor: Very Simple Intersection iMA Open Position

I corrected my problem. I created the handle in the oninit function. 

I had gotten bad examples from some YouTube videos where the handle is created in ontick function. 

Thanks again for your examples.
