We are updating RSI indicator using historical dataset. In some scenarios, RSI is 0.0.

 

SetStartDate(2019, 06, 15);
SetEndDate(2019, 06, 29);
var currentRSI = new RelativeStrengthIndex(14, MovingAverageType.Simple);

foreach (TradeBar tradeBar in tradeBarHistory)
{

currentRSI.Update(tradeBar.EndTime, tradeBar.Close);
}

Could it be data issue or am I doing something wrong in the code?
