Thanks Wayne, I actually tried that one.
Amazing 3-d graphs, very nice interface, but no volatility input or output, except one overall for all options on a stock.
One 3-d combo graph had me quite enthusiastic about a positionâs P/L until I realized: you download real option quotes, each with its own IV (which are not calculated/shown at all) and then it plots a P/L graph based on one overall volatility that you can manually adjust.
Iâm no expert but I wondered: how does it calculate a combo P/L till expiration when it starts off with different IVâs and then uses the same for all legs? Am I making sense?
