NinjaTrader FixRisk

A simple NinjaTrader 8 indicator for quick and precise position sizing based on your desired risk per trade and stop distance. Built for professional discretionary futures traders who prefer clear, rule-based risk management. Ideal for fast scalping as well as any kind of position sizing based on market entries.

⚙️ Features

• Calculates optimal position size based on:
  • Fixed risk amount (in account currency)
  • Stop-loss distance (defined by chart line)
  • Instrument tick value
• Automatically fills the Chart Trader → QTY field
• Displays position size and risk information directly on the chart
• Automatically references the Ask price for long trades (stop below market) and the Bid price for short trades (stop above market)
• Lightweight, zero-dependency, and open-source

📦 Installation

1. Download FixRisk.cs
2. In NinjaTrader:
   • Go to New → NinjaScript Editor
   • Right-click the Indicators folder → New Indicator
3. Press Generate
4. Remove all default code
5. Paste the contents of FixRisk.cs
6. Press the Compile button at the top of the NinjaScript Editor window

🧠 Usage

The red line represents your imaginary stop-loss for the calculation. If you place a market order and set your actual stop exactly at that line, a stop-out will result in a loss equal to the risk amount you specified in the indicator settings.

1. Set your desired risk per trade (in account currency)
2. Position the red line where your stop-loss would be
3. The indicator automatically:
   • Calculates and displays the optimal position size on the chart
   • Updates the Chart Trader’s QTY field accordingly
