Hi, I am contemplating to trade a futures system on IB via either multicharts or amibroker taking the underlying data from esignal. I want to develop the system off a proportionally adjusted continuous futures contract. Had a question regarding continuous contracts: 1. Multicharts seems to allow proportional futures contracts as per this webpage however if I use eSignal as the underlying data, eSignal only allows difference method for making continuous futures contracts as per this webpage . A 101 basic question: does Multicharts pull out individual futures contracts from eSignal and then create its own continuous contracts or do we need to subscribe to a data source (like csidata) which by default allows proportionally adjusted continuous futures contract? 2. For Amibroker - I couldn't find any information about continuous futures contracts? Thanks, pb273
