Hello, I am interested in trading commodity options actively and I am looking for a cheap analysis software. What I would typically like to be able to do is charting several intercorrelated products volatility smiles( equity indexes, soy and soy products... ) and chart volatility surfaces per products including long deferred new crop expiries... Is their something similar to Hoadley for futures? I am not looking for professional tools at 1K+ per month but just a cheap excel interface for TWS or something similar... Otherwise, if I have to code my own spreadsheets, do you think I can use IB TWS implied vol values directly or recalculate? Thanks a lot.
