Strategy Builder - Quantity

[Rubens_2020]

Hello to all,

Previously, when I was building a strategy using "Strategy Builder", under "Conditions and Actions" I used to go to Actions --> Order Manage --> Enter long position --> Quantity (set) --> Misc --> Numeric value and put the number. But now, I am not able to enter the numeric value for quantity. Could anyone help or guide me.

Thank you and have a wonderful evening!

Hello Rubens_2020,

Thanks for your post.

The Strategy Builder was changed to remove the Misc>Numeric value so that you could more simply just delete "default quantity" and directly type in the quantity to use, however, we found that this was not consistent. This will be fixed in the next release of NinjaTrader8 so that you should be able to enter the value directly.

In the meantime, there are two ways to deal with the quantity.

1) Create a user input (int type) where you specify the quantity and then in the quantity filed click set and select user input (name of user input you created). This also allows you to change the quantity when you apply the strategy.

2) Leave it as default quantity and when you apply the strategy, in the strategy parameters, look for the section "Order properties", locate the line "set order quantity" which will show "Strategy" and you can change it to "default quantity" and that will reveal the default quantity field that you can then directly change.

Hi,

I too have a question about the quantity of orders.

I set an Input to Int, but how do I select 0? I have multiple options in the same strategy (Long/Short) and would like to select a quantity for both, so I have two Inputs. If I select 0 it automatically defaults to 1. So I can run any number above 1, but what if I want to run only Long or Short positions? I set the default value to 0 in the Inputs and Variables in Strategy Builder, but it never runs 0. How can I do that? I tried using a Double, but that did not work either. It would still run 1 contract even when selecting 0.

Thanks

Hello david196,

Thanks for your post and welcome to the NinjaTrader forums!

When you create an int entry in the strategy builder, observe that it will create both a "default" value of 1 and a "min" value of 1. If you do not change the value it will be 1. If you do change the value to be less than 1 then it (the strategy builder) will set it to the minimum value of 1.

If you want to control which side takes a trade, at the time you apply the strategy, you can create two bool variables, that are set true by default. In the entry sets add the condition to check that the bool variable for that side (long or short) is true. When you apply the strategy you can simply uncheck the bool check box.

Thanks Paul, I have been using the Help Guide and found the Strategy Builder 301 online as well, but was not aware of the Free live webinars. Something to look at, for sure.

I have a couple of more questions on the Strategy Builder (but not related to order quantity), how do I create a new post? Is it "Send new message"? I thought that would send a message to a specific user...

Thanks
David
