0dte risk reality coach

The problem

Traders often treat 0DTE options like lottery tickets, ignoring the structural forces of theta decay and gamma acceleration. Without a concrete risk map, same-day positions can hit maximum loss limits in minutes due to slippage and time pressure.

What it does

• Calculates hourly theta decay to show the cost of holding a position as time passes.
• Maps gamma sensitivity to project how delta shifts during price swings.
• Analyzes bid/ask spreads to estimate realistic exit slippage and liquidity risk.
• Enforces non-negotiable dollar-based maximum loss rules and hard time-based exits.

Why this beats prompting it yourself

This skill moves beyond basic Greeks by translating abstract data into a "Risk Reality Map." It forces pre-commitment to exit strategies, preventing the emotional "hope-based" trading that typically leads to 0DTE blowups.

Use cases

• Reviewing the risk profile of a SPY 0DTE call or put before entry.
• Calculating the impact of a 1% move against a live same-day position.
• Setting hard time-based exit deadlines for index options.
• Determining maximum contract size based on a fixed dollar risk limit.

Known limitations

Does not provide directional predictions or financial advice. Requires manual entry of option chain data like Greeks and spreads for the most accurate mapping.
