Vega Options VS https://open-gpt.app/

• Gamma Exposure (GEX) + Gamma Pin
  Visualize where dealer hedging creates gravity in the market. The Gamma Pin identifies the strike where dealer flow flips from stabilizing to amplifying price moves, a level the market tends to gravitate toward into expiry.
• Open Interest Butterfly
  Call and put OI plotted side-by-side at every strike. Spot support and resistance walls instantly, with outlier strikes clipped automatically so the ATM action is always front and center.
• Max Pain & Key Metrics
  Real-time max pain, implied move, put/call OI ratio, and put/call volume ratio, all surfaced as a metrics bar above every chart. The numbers that matter, without the math.
• Earnings Expiry Signal
  Upcoming earnings dates are detected automatically. The first post-earnings expiry is flagged in the discovery panel, so you're never accidentally analyzing a pre-event chain.
• P&L Simulator
  Model your position before you place it. Adjust underlying price, implied volatility, and days to expiry to see exactly how your P&L moves across scenarios, before a single dollar is at risk.
• Signal Interpretation
  A built-in analysis layer reads the chain for you, classifying OI positioning, IV skew, and volume conviction into a plain-English directional signal across multiple expiries simultaneously.
• IV Skew Chart
  Implied volatility across every strike, calls and puts overlaid on a single chart. A steep put skew means the market is pricing real downside risk. See it before it shows up in price.

Possible disadvantages

• Uncertain Reliability
  Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
• Data Privacy Concerns
  Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
• Limited Transparency
  It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
• Potential Hidden Costs or Ads
  Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
• Lack of Official Support
  Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
