Hi, I've recently subscribed to Esignal and Im having a real difficult time trying to get a spread chart plotted based upon the "day's change". For instance, if I want to use the following formula: (2.5 * MSFT(change from prior close) - (dell(change from prior close). So if MSFT is up say +.35 on the day, and dell is +.25, my spread should be plotting and charting +.625 or .63 if it has to round up. Im trying to get this calculated in 'change of price' and all I can do is multiply it by the last price. I can't figure out how to get the 'days net change' to be used for my formula. Any suggestions or help would be great. I've been on the esignal bulletin board and been told that I need to create an efs. I have NO programming abilities, nor do I have the time to learn EFS. And I really have been researching this and wasting alot of time over the last 10 days or soo. What Im trying to do, (which I think should be pretty basic and is not very original) has been really hard to find with all the free efs and examples out there. Does anyone know of a similar efs? or would be willing to share or help me create it. Im starting to research some outside companies that program these types of things, but that might get a little pricey for something that really seems soo simple and something my data provider should provide. Any suggestions? Thanks.
