Hello all, I am a fund manager from Switzerland specialising in FX and wish to explore futures trading as part of our portfolio. We are systematic traders. I have three questions that I can't seem to find in any other way and hope some of you may help me out. I will ask them one by one if you don't mind. 1) When looking at a historical chart of a futures contract (e.g. an index future), I am looking at a continuous chart. Does that mean that all the individual contracts have been connected? How is this done? I assume at the time of expiry, the difference between the expiring contract and the new contract is simply added or subtracted to every historical data-point to make a single graph? Is this something you do yourself as a trader, or does your charting software or data provider do automatically for you? Thanking you kindly.
