Risk/Reward Ratio Table Calculator

**Risk/Reward Ratio Table Calculator - Professional Position Sizing Tool**

This indicator provides a comprehensive risk management planning table for traders seeking to maintain consistent risk/reward ratios while respecting broker leverage limits and avoiding margin call scenarios.

**What This Script Does (NOT a Mashup):**

This is an original risk management calculation engine, not a combination of standard indicators. It uses a proprietary binary search algorithm to automatically calculate optimal position sizing that simultaneously:

1. **Binary Search Algorithm**: Iteratively finds the optimal position sizing multiplier through thousands of calculations that validate each configuration against your broker's margin requirements.

2. **Cumulative Loss Tracking**: Calculates realistic accumulated losses through sequential trades, allowing traders to understand the impact of consecutive losing trades on their account.

3. **Margin Call Protection**: Ensures individual trade exposures (Risk % × Leverage) never exceed your broker's safety threshold, preventing forced liquidation.

4. **Recovery-Based Position Sizing**: Unlike static position sizing, subsequent trades adjust their risk percentages to incorporate a configurable recovery factor, allowing traders to progressively recover losses while maintaining viable margin levels.

5. **Real-Time Dynamic Rebalancing**: The table recalculates as you adjust parameters, providing instant feedback on how leverage changes, different risk/reward ratios, or varying safety margins affect your trading plan.

**How It Works:**

- Step 1: Input your risk tolerance (initial %), broker leverage (1:X), and risk/reward ratio (e.g., 1:4)
- Step 2: Algorithm calculates maximum viable trades while respecting safety margin
- Step 3: For each sequential trade, computes: individual risk %, potential profit, cumulative loss, recovery target, and real exposure
- Step 4: Color-coded table displays results with warnings for high-exposure trades

**Key Original Calculations:**

The script employs a proprietary binary search algorithm testing thousands of position-sizing configurations. For each trade n:
- Cumulative Loss = Sum of all previous trade risks
- Risk% = (Cumulative Loss + Target Gain) / Risk-Reward Ratio
- Target Gain = (Base Gain × Multiplier × Recovery Factor) + Base Gain(1 - Recovery Factor)
- Exposure = Risk% × Leverage × 100

This specific combination—simultaneously optimizing for maximum trades, consistent ratios, sequential loss recovery, AND broker margin safety—cannot be replicated by combining standard indicators.

**Use Cases:**

1. **Scalpers** (1-5 min): Plan tight money management with 1:2 to 1:3 ratios
2. **Day Traders** (5 min - 4 hour): Plan daily sequences with 1:3 to 1:4 ratios
3. **Swing Traders** (4 hour - daily): Plan weekly sequences with 1:4 to 1:5 ratios
4. **Risk Managers**: Calculate maximum daily trades without margin call risk

**Parameters:**

- **Risk/Reward Ratio**: Your target ratio (1:4 means risking 1% to gain 4%)
- **Leverage (1:X)**: Your broker's leverage (CFDs: 1:30-1:500, Futures varies)
- **Initial Risk (%)**: Starting risk percentage (0.5% conservative, 1.0% moderate)
- **Number of Trades**: Sequential trades to plan per session
- **Safety Margin (%)**: Capital held in reserve (20-30% recommended)
- **Recovery Factor**: How much of losses to recover (1.0 = full recovery)

**Table Color Coding:**

- Green header: Main parameters
- Red column: Accumulated losses increasing through sequence
- Yellow column: Individual trade risks
- Orange column: Recovery targets in TP
- Green column: Potential gains
- White column: Net P&L for sequence
- Exposure column: Leverage exposure with warnings (Green < 50%, Yellow 50-75%, Orange 75-90%, Red 90-99%, Dark Red 99%+)

**Originality Statement:**

This script's core algorithm—the binary search position-sizing engine—is original work. While position sizing concepts are well-known, this specific implementation simultaneously optimizing for maximum viable trades, consistent risk/reward ratios, sequential loss recovery, and broker margin call avoidance represents a unique contribution distinct from any simple indicator combination.
