Institutional Average True Range Risk Manager

Dynamic Volatility-Based Position Sizing & Margin Protection Engine.

Overview: Developed by Adaptogen Systems, the Institutional ATR Risk Manager V2.0 is an essential on-chart utility for serious quantitative and retail traders. Stop guessing your lot sizes or using static volumes that ignore market regime shifts. This Expert Advisor utilizes dynamic True Range (ATR) metrics combined with a universal tick-math engine to instantly calculate your precise lot size across any asset class—Forex, Metals, Indices, or CFDs.

Simply input your desired Capital Risk (%) and your Stop Loss ATR Multiplier. The engine handles the complex instrument specifications, calculates the absolute risk, normalizes the volume to your broker's limits, and verifies your available margin before outputting the mathematically optimal position size.

Core Architecture & Features:

• Universal Tick-Math Engine: Seamlessly adapts to 5-digit Forex pairs, 2-digit Indices (e.g., US30, JPN225), and volatile Metals (GOLD#) without requiring manual parameter tweaks.

• Dynamic Volatility Sizing: Adapts your Stop Loss distance based on the current Average True Range (ATR), ensuring your risk scales proportionately with market expansion and contraction.

• Institutional Margin Protection: Features a built-in OrderCalcMargin security subroutine. If a requested risk profile exceeds your account's free margin, the system automatically scales the lot size down to the safest mathematical threshold, preventing "Insufficient Funds" execution errors.

• Transparent GUI: Displays critical derived metrics (Stop Loss Distance in Points and Actual Capital Risked in account currency) alongside the final lot size, ensuring total mathematical transparency before you execute a trade.

• Lightweight & Non-Intrusive: Built on a strict Object-Oriented Standard Library UI that operates smoothly over any chart template without lagging the terminal.

Input Parameters:

• ATR Period: The baseline lookback period for volatility measurement (Default: 14).

On-Chart Interactive Inputs:

• Risk Percent (%): The exact percentage of your current account equity you wish to risk per trade.

• ATR Multiplier: The distance of your Stop Loss, expressed as a multiple of the current ATR value.

Usage Instructions:

1. Drag the utility onto any active chart.

2. Enter your desired Risk % and ATR Multiplier in the interactive panel.

3. Click "CALCULATE LOT SIZE".

4. The panel will instantly output your exact Stop Loss distance, the monetary risk, and the optimal lot size normalized to your broker's minimum and maximum volume steps.
