Setting Stop Loss between VWAP and LOD

[BrJessey]

I am trying to make a long order and set the stop at 1/3 the way between VWAP and LOD.
It compiles fine , but I get Error on calling 'OnStateChange' method Object: reference not set to an instance of an object.
Here is the code that I think is the issue

EMA1 = EMA(Close, 9);
VWAP1 = VWAP(Close);
VWAP2 = VWAP(Close);
CurrentDayOHL1 = CurrentDayOHL(Close);
Stopticks =(int)((VWAP2.PlotVWAP[0] - CurrentDayOHL1.CurrentLow[0])/3);
BarCounter1 = BarCounter(Close, true, Brushes.Gray, 14, 50, true);
SetStopLoss(@"Long",CalculationMode.Ticks, Stopticks, false);
SetProfitTarget(@"Long", CalculationMode.Ticks, Stopticks);

Hello BrJessey,

Thanks for your post.

"Error on calling 'OnStateChange' method Object: reference not set to an instance of an object."

This error indicates that something you are accessing in the script is not defined at the time you are accessing it.

In the code you shared, this is not the correct VWAP syntax for defining a VWAP indicator. The VWAP syntax is noted in the help guide and can be seen below.

OrderFlowVWAP(VWAPResolution resolution, TradingHours tradingHoursInstance, VWAPStandardDeviations numStandardDeviations, double sD1Multiplier, double sD2Multiplier, double sD3Multiplier)

See this help guide page for more information on accessing Order Flow VWAP values and sample code: https://ninjatrader.com/support/help...flow_vwap2.htm

Further, indicator values should be accessed in OnBarUpdate(). You could consider setting up your Stopticks calculation in OnBarUpdate() and then use Exit methods in OnBarUpdate() for your stop loss and profit target orders.

Attached is a simple example script demonstrating using Exit methods for stop loss and profit target orders which you might find helpful.
