What is WMS's gamma exposure (GEX) today?

How is WMS gamma exposure calculated?

OptiView multiplies each open WMS contract's gamma by its open interest, contract size, and the square of the share price, counting calls as positive and puts as negative dealer exposure. Summing across all strikes and expirations gives net GEX; the per-strike breakdown is shown in the chart above.

Methodology. IV rank compares the current 30-day at-the-money implied volatility with its highest and lowest values over the past 52 weeks. Max pain is the strike that minimizes the total payout to option holders at expiration. The call and put walls are the strikes carrying the largest call and put open interest across all expirations. Net gamma exposure (GEX) is measured from the dealer perspective. All statistics are derived from delayed OPRA options data.
