Martingale Strategy in Strategy Builder

[tradersgrail]

Anyone have any idea how to create a martingale strategy in the strategy builder?

Hello tradersgrail,

Thank you for your post.

From my understanding, a martingale strategy has to do with a strategy that has you double your position after a losing trade. This may be difficult in the strategy builder, but depending on the logic you use may be a possibility. It would almost certainly be easier to do by unlocking the code and actually programming the strategy directly using NinjaScript.

If you know the logic you would like and can write this as psuedo code in plain English, we can assist you in writing this as logic in C#. This thread will also remain open for any community members that know of an existing strategy with this functionality or who would like to create this as a convenience to you.

I'm providing a link to a pre-recorded set of videos 'Strategy Builder 301' and 'NinjaScript Editor 401' for you to view at your own convenience.

Hello abdelkrikib,

Thank you for your reply.

Looks like an error is being hit within the OnStateChange() method of the strategy. If the Strategy is still editable in the Strategy Builder, you can click the View Code and copy what you've currently got in OnStateChange() and then paste the text of that in your reply. If you've already unlocked it, you can copy and paste from the NinjaScript Editor, but I'd like to see if there's something obvious you've got in that method that would throw an error.

Thanks in advance; I look forward to assisting you further.
