Option Calculator

Option Calculator – Comprehensive Feature Guide
The aiTrendview Option Calculator is a feature-rich options trading dashboard built using Pine Script, designed for real-time market interpretation and strategy selection. It integrates Black-Scholes-based pricing models with dynamic market inputs to help traders evaluate directional bias, volatility, risk, and potential profitability in a structured, intuitive format. The tool supports both beginner and experienced options traders in making data-driven decisions.


Core Inputs and Pricing Foundations
Users can input the strike price, days to expiration, implied volatility (IV), interest rate, and option type (call or put). These values feed directly into calculations for the option's theoretical price, Greeks, and expected move. For example:
• Strike Price helps define moneyness, impacting delta and risk/reward balance.
• Days to Expiry determines the speed of time decay (theta).
• Risk-Free Rate adjusts for time value and interest rate impact (rho).
• Implied Volatility affects premium pricing and vega exposure.
• Option Type sets the directional foundation for strategy analysis.

Live Market Data Integration
The script pulls current underlying price, price change, and volume comparison against a moving average (e.g., current volume vs. 20-day average). This helps identify unusual trading activity or volume spikes. Volatility readings are also incorporated using ATR or external volatility indexes to enhance the realism of IV assessments.


Greek Calculations
The dashboard provides visual and numerical values for all five major Greeks:
• Delta shows directional sensitivity and is plotted with a visual bar.
• Gamma represents the rate of delta change, especially critical near-the-money.
• Theta measures time decay and is most impactful in the final weeks before expiration.
• Vega tracks sensitivity to volatility shifts, crucial for premium-selling strategies.
• Rho reflects sensitivity to interest rates, primarily relevant in long-dated options.
Each Greek is calculated based on real-time inputs, providing a statistical framework for assessing risk and return.


Market Sentiment & Risk Environment
A sentiment scoring system interprets the put-call ratio (PCR), volume trends, and price momentum (e.g., RSI). IV levels are color-coded (e.g., low, medium, high) to identify whether options are relatively cheap or expensive. These values support better timing decisions and help identify whether to be a buyer or seller of premium.

Strategy Recommendation Engine
The script dynamically evaluates six core strategies based on current data:
1. Long Call
2. Short Put
3. Long Put
4. Bull Call Spread
5. Long Straddle
6. Iron Butterfly
Each strategy is assigned a confidence score (0–100%) and updated in real-time. This system is designed to match the appropriate strategy to market conditions such as trend, volatility, and time to expiration.

Risk-Adjusted Trading Insights
The dashboard helps traders evaluate whether to initiate trades, reduce exposure, or wait:
• High Confidence (80%+): Favorable environment; standard sizing recommended.
• Moderate Confidence (60–80%): Trade with caution and reduced risk.
• Low Confidence (<60%): Consider avoiding the trade or waiting for better setup.
It also supports risk mitigation through defined-risk strategies and provides guidance on stop-loss, profit targets, and time-based exits (e.g., managing options with <21 days to expiry).

Real-Time Monitoring
The script continuously tracks:
• Changes in Greeks as price, volatility, or time evolve.
• Profit probability estimates using expected move and breakeven pricing.
• Volume activity and IV rank to spot institutional behavior.
This empowers traders to manage trades proactively, adjust exposure, or lock in profits based on changing market conditions.


Practical Use Case Flow
Step 1: Input Setup
Enter option-specific parameters (strike, expiry days, IV, etc.) and let the dashboard auto-calculate risk metrics.
Step 2: Analyze Market
Use sentiment analysis, IV level, and volume data to understand the environment.
Step 3: Select Strategy
Rely on the confidence score and recommendation engine to choose a suitable options strategy.
Step 4: Manage Risk
Apply size rules based on signal strength, adjust based on exposure, and set alerts if needed.
Step 5: Monitor Outcomes
Track Greeks, probability, and progress metrics to stay informed throughout the trade.


Trading Environment Adaptation
• Low IV: Favor long premium strategies (e.g., long straddles, long calls).
• High IV: Favor premium selling strategies (e.g., iron condors, credit spreads).
• Bullish Markets: Focus on call-based trades or bullish spreads.
• Sideways Markets: Use neutral setups like iron butterflies or calendar spreads.
Position sizing and stop-loss logic are aligned with industry practices (e.g., risk no more than 2% per trade, take profit at 50%, and cut losses at double the premium received).


Dashboard Interpretation Guide
• Green: High confidence strategy, favourable IV, and strong volume confirmation.
• Yellow: Mixed signals or moderate conviction – proceed with caution.
• Red: Low confidence, poor conditions – better to wait for clearer opportunities.
