Automatic contract size calculator based on risk% and interactive stop loss

[aronstrades]

Hey everyone!

I'm new here, just migrating to NinjaTrader from Metatrader. Loving the platform so far, but I'm missing something that was very essential to my trading style (scalping on the 1 min).

I'd like to code something similar to this: https://www.earnforex.com/metatrader...osition-Sizer/
It's a free position size calculator for the Metatrader platform which automatically calculates your lot/contract size in real time based on an input risk% of your account balance and an interactive stop loss level that you can drag on the chart. (The program does a lot more that this, but to keep things simple that's the gist of it.)

Honestly if I could create something where there's an interactive stop loss level that just displays a contract size based on a customizable risk% input... I'd be happy. It seems like a very simple thing to code but since I'm new to the script language, I don't even know where to begin.

Can someone with experience offer some guidance? Is it even as simple as I imagine?

Hello aronstrades,

Welcome to the forum!

Please read through this forum post on getting started with NinjaScript:

You can access account level items, like account balance, using .Get() and AccountItem.

You can set your stop loss using SetStopLoss() based on your custom risk calculation.

Oh finally someone! Coming from Metatrader to Ninjatrader I feel I've returned to the year 1900. A dismal third party monopoly and exaggerated pricing for trade managers. My MetaTrader trade manager is considered magic in comparison.
Have you found any solution?
