Custom User Made ATM for Indicator Trail Stop Possible?

[shodown888]

Hello I would like to know if it is at all possible to create a custom ATM that is scripted to trail a stop using an indicator plot such as 9 SMA? Any way to add a different ATM than what is available in the drop down? I know we can add strategies outside of it, but I would like to ideally apply the strategy after a trade is initiated.

Hello shodown888,

Thanks for your message.



First, be aware that it's not possible to add an ATM Strategy once a position has been opened, as there's no supported method to add an ATM to a position from NinjaScript.

While not officially documented or supported, there is an unsupported code to protect an open position, which was shared on our Forum website.

AtmStrategy.ProtectPosition(selector.SelectedAtmSt rategy, Position);

Another alternative is to use Set Methods to protect your position. The link below contains examples on how to do so.

Also, the NinjaTrader platform comes with a built-in sample ATM strategy code that demonstrates how the ATM is created within NinjaScript. On the Control Center, Click on New>NinjaScript Editor. On the right side of the window, open the strategy folder, and you will see the file SampleAtmStrategy. This sample will give you a breakdown of all the steps that are taken to create an ATM strategy within your script.



Next, the add-on approach would be needed to modify any of your orders using Account.Change().

Note that an Atm with a stop strategy would supersede any modifications made by a script.



Finally, the most efficient approach would probably be to submit the entry through a script ( via a button click in a custom Add-On), and then automatically submit associated stop and target orders once the entry is filled. The stop and target prices should be dynamically controlled through code.
