Alert indicator for StochRSI and EMA not working

[cyberpete76]

Hello, I have this code for an indicator that should trigger an alert, if some conditions for StochRSI and EMA are met. But I am getting erro code CS0103 from the compiler, that StochRSI "does not exist in the current context". But Stoch RSI is a standard indicator in NinjaTrader, or is it not?
Could you please check what could be the problem?
Thanks a lot!

Hello cyberpete76,

Alerts only appear in real-time.

May I confirm State is State.Realtime when checking this condition?

"if(CurrentBar == Bars.Count -2"

This condition checks if current bar is count minus 2, which is typically how to find the last historical bar, and of course in historical Alerts cannot be triggered. In real-time this will always be true as both the Count and CurrentBar will always be increasing.

"&& ((ema20[0] < ema50[0] && stochRsi.Current[0] >= 0.8) || (ema20[0] > ema50[0] && stochRsi.Current[0] <= 0.2))"

How do you know this part of the condition is evaluating as true. In real-time the alert will only be sent if the condition evaluates as true.

Please provide the output from prints showing that this condition is evaluating as true.

Hi Chelsea,
yes I need this to work in realtime. I have other indicators already working exactly the same way. I just needed another one for a different strategy I want to test.
The conditions should be correct. But as discribed in my first post, my problem is the error code CS0103 I am getting from the compiler, that StochRSI "does not exist in the current context".
So there is something wrong with the stoch.RSI definition in my code.

Thanks
Peter

Hello Peter,

There is no Add() method in NinjaTrader 8.

Where you trying to use AddChartIndicator()?
https://ninjatrader.com/support/help...tindicator.htm

Yes, the StochRSI(int Period) is an indicator that is supplied with the installation of NinjaTrader.

Note its a uppercase 'S', lowercase 'toch', uppercase 'RSI'. C# is case sensitive. You will need to match the help guide.

Also, this has a Period input. The other 2 numbers you are putting in the method call are not valid.

Below is a link to the help guide.
