Hello, There is so much conflicting information on futures rollover/ active months. I am looking for a reliable futures rollover rule based calendar similar to what exists here: http://pinnacledata.com/clc.html The pinnacle data site seems OK, but I want a site to compare. Also I am interested in knowing what are the active months for commodities. For example index & FX are on a quarterly expiration cycle, Gold is different with active months being: Feb, April, June, Aug, Dec What would be active months for: Silver, Copper, the energy products (CL, NG, BRN, GAS, RBOB, Heating Oil), corn, soy, wheat, Eurodollar, Euribor. Please fell free to upload spreadsheets or documents. Thanks!
