Where to get charts that substract one future contract from another (for spreads)? Also for calculating Contango/Backwardation?
most software packages can do that. I have e-signal and all you have to do to create a spread chart is to type one symbol, press space bar, then minus sign, space bar, then other symbol. example: YM #F - NQ #F. You can also put a +, / , or * sign.
Think or Swim are the current Kings of walk on this one. High tail it over there and I'm sure they'll be happy to help. GL
