Casting Error

[Vikuno1]

Hello,

I am getting this error and want to know if there is a way around it.

I have an indicator that is looking through the strategies on the chart and saving one so that it can be edited but I keep getting this casting error because the strategy I am trying to save is saying it is not of type strategy. Here is the code I am using to get the strategy

if(ChartControl != null && strat == null)
{

foreach(Strategy s in ChartControl.Strategies)

{

if(s.Name.ToUpper() == StrategyName.ToUpper())
{

strat = s;

}

}

}

I also tried

if(ChartControl != null && strat == null)
{

foreach(var s in ChartControl.Strategies)
{

if(s.Name.ToUpper() == StrategyName.ToUpper())
{

strat = (Strategy) s;

}

}

}

But I keep getting this error
Error on calling 'OnBarUpdate' method on bar 5038: Unable to cast object of type 'NinjaTrader.NinjaScript.Strategies.ARC.ARC_VABOAl go' to type 'NinjaTrader.NinjaScript.Strategies.Strategy

Any idea on how I can cast and not get this error?

Thanks!

Hello Vikuno1,

You may need to cast as StrategyRenderBase as this is the collection type.

It says that type or namespace cannot be found. What library do I need to use?

Will I still be able to access the position of that strategy?

Thanks for the speedy reply!

Hello Vikuno1,

NinjaTrader.Gui.NinjaScript.StrategyRenderBase

"Will I still be able to access the position of that strategy?"

This is not a supported approach so this would not be guaranteed.

[Vikuno1]

Ok so I realize it may not be supported but wanted to ask anyway.

I was able to not cast and just grab the current strategy on the chart with ChartControl.Strategies[0]

From there I can Exit/Enter in my indicator by using commands like so "ChartControl.Strategies[0].ExitShort("Blah", "");"

It works for the Sample MA Crossover but when using it on a specific strategy I get the error that is attached below. Ignore the tooltip just look at the orange error

Any ideas?

Hello Vikuno1,

The error appears to state that a Profit target order does not have the same quantity of the position.

[Vikuno1]

Yes, that is what it says.

I am using the function
ExitLong()

so it should automatically calculate the entire position. Also it actually does exit the entire position but then will throw that error and disable the strategy

Hello Vikuno1,

Is this at the same time a profit target is working?

If so, use Exit orders for the profit target and cancel the order before placing the ExitLong() order.

I don't have access to the original strategy, I am just trying to have it exit based on my own logic. So I should try and cancel the stop and profit target that it uses first and then market order exit?

Hello Vikuno1,

Yes, use Exit orders for the stop and target, cancel these before sending a replacement order.
