According to GreeksLive, a professional options tool is now offering detailed and customizable options metrics for professional traders. On the X Web platform, traders can access specific metrics in their options portfolios, such as '1% Cash Gamma', which calculates the dollar impact of a 1% move in the underlying asset using the formula: 0.5 * Gamma * (index price * 0.01)^2. Additionally, the tool provides the 'Vanna' metric, related to the sensitivity of implied volatility to Delta.
