defaulting strategy setup parameters in code

[marcow]

Is there a way to define the "order properties" of a strategy in the code of that strategy ; when starting a new strategy, I have to manually set order properties to "by default quantity", it would be nice if that setting could be defaulted in the strategy-code. I know this can be done for "Calculate on bar close" but is it also possible for order properties in the strategy configuration window ?
If yes, how can this be achieved ?

Marco, what you could do is set the default quantity in the strategy Initialize() - http://www.ninjatrader-support.com/H...tQuantity.html

Bertrand,

I put

 
DefaultQuantity = 1;

in the strategy Initialize() but unfortunately it doesn't seem to work.

When I start the strategy and look under "Order Properties" in the setup window, I still see "Set order quantity: by strategy" in that field.
I would like this field in default to be "Set order quantity: by default quantity" and "default quantity = 1 "

Reason for this is that each time I start the strategy I have to alter these Order Properties settings by hand (and yes, sometimes forget to do so..). It would be very usefull to set and fixate the Order Properties from within the strategy code. Can this be done ?

Hello Marcow,

Unfortunately hard coding this value is not supported. You will have to change through the GUI.

ahh, now I get it....

in the variables section of the code I define a variable Contracts = 1
And then in the Initialize() section defaultQuantity = Contracts

When starting the strategy the variable Contracts will default at 1 as defined in the code, but still can be changed as desired.
Order Properties field can now remain the default " by strategy" because DefaultQuantity is now set via the Contracts variable.

thank you.

Thanks for sharing a work-around to this, marcow! Glad you were able to get it sorted.

I found a much more elegant solution using "QuantityType = QuantityType.DefaultQuantity" which is exactly what I was looking for

protected override void Initialize()
{
DefaultQuantity = 1;
QuantityType = QuantityType.DefaultQuantity;
TimeInForce = Cbi.TimeInForce.Day;
}
