Adding a Button to a Chart to Interact with a Strategy

[NinjaCustomer]

I found this sample:

https://ninjatrader.com/support/help...collection.htm

if I add a button to the chart, how can I get it to interact with 1 or 2 more strategies that are running on the chart?

I haven't really thought it through but I guess I would want to set a flag or enum within the Strategy once the button is clicked.

note: Regular Strategy, not ATM Strategy

Hello NinjaCustomer,

Thanks for your post.

Buttons would be added from a specific NinjaScript and would only have control over that NinjaScript. You could consider to have the button set a static variable that resides in the AddOn namespace and then have your strategies take an action checking that bool in their OnBarUpdate methods. An example for sharing information between NinjaScripts taking this approach can be found below.

We look forward to being of further assistance.

what type of NinjaScript should I use to create the Buttons? an Indicator?

I assume it is not possible to create them from within a Strategy (although that would be ideal if possible)

Hello NinjaCustomer,

An indicator or strategy can add buttons to a chart. An example for adding buttons to a strategy can be found below.

Hi Jim, so just to confirm - if I make a Strategy that adds buttons to the chart then I don't need to deal with the hassle of the "AddOn namespace" ? I can just set a flag within the Strategy itself?

[NinjaTrader_Jim]

Hello NinjaCustomer,

The example strategy adds buttons that will only work in the scope of that strategy. If you would like to have the buttons work across multiple strategies, then the buttons would have to modify static variables in the AddOn namespace and each strategy will have to read these static variables to take a certain action.

Please let me know if you have any additional questions.

In this post, there is a reference to:

I have downloaded this file and added it to a chart. But when I tried to test it during Playback I can't enable it.
Is there a reason I can't test this Button add on in Playback?

regards,
Taddypole

[NinjaTrader_Jim]

Hello Taddypole,

Please make sure there is data on that instrument, and please ensure that the Playback account is selected when testing the strategy. I suggest opening a new chart and enabling the strategy on the new chart to ensure the data is there and that you can select the proper account.

We look forward to assisting.

For some reason, I have to remove the strategy and then re-apply it. Then it works.

is there an indicator that places a button on the chart ,that can be seen in strategy builder to set as a condition if the button was pressed (say it should have the value "1" )

Hello yBl123,

Thanks for your notes.

I am not aware of any existing indicators that accomplish this specifically.
