Sizing Coach HUD Long and Short

This HUD is designed as a systematic execution layer to bridge the gap between technical analysis and mechanical risk management. Its primary purpose is to eliminate the "discretionary gap"—the moment where a trader’s "feeling" about volatility or spreads causes hesitation.

By using this tool, you are not just watching price; you are managing a business where Risk is a constant and Size is a variable.

Core Functionality: The Position Sizing Engine
The HUD automates the math of "Capital-Based Tiers". Instead of choosing an arbitrary share size, the system calculates your position based on three predefined levels of conviction:

Tier 1 (1% Notional): Low-confidence or high-volatility "tester" positions.

Tier 2 (3% Notional): Standard, high-probability setups.

Tier 3 (5% Notional): High-conviction trades where multiple timeframes and factors align.

Execution Workflow (The Poka-Yoke)
To use this HUD effectively and eliminate the "hesitation" identified in the Five Whys analysis, follow this workflow:

Toggle Direction: Set the HUD to Long or Short based on your setup (e.g., NEMA Continuation).

Define Invalidation: Identify your technical stop (default is High/Low of Day +/- 5%). The HUD will automatically calculate the distance to this level.

Check Risk $: Observe the Risk $ row. This tells you exactly how much you will lose in dollars if the stop is hit. If the volatility is extreme (like the SNDK 14% plunge), the HUD will automatically shrink your Shares count to keep this dollar amount constant.

Execute via HUD: Transmit the order using the Shares provided in your selected Tier. Do not manually adjust the size based on "gut feeling".

Trade Management: The "R" Focus
The bottom half of the HUD displays your Targets (PnL / R).

VWAP & Fibonacci Levels: Automatically plots and calculates profit targets at key institutional levels (VWAP, 0.618, 0.786, 0.886).

Binary Exit Logic: The color-coded logic flags any target that yields less than 1R (Reward-to-Risk) as a warning.

Systematic Holding: Ride the trade to the targets or until your technical exit (e.g., 1M candle close above/below NEMA) is triggered, ignoring the fluctuating P&L.
