The external file (XFILE) feature that I mentioned is only available in 4.x. I made a feature request some while back that Jeff took seriously. If I define a custom indicator like this: metric := XFILE("active/<t/ticker>/PriceMPR_ME_DR/PriceMPR_ME_DR.txt"); ProTA looks for a configurable directory root, and then looks for a folder that I define as "active", then looks for a folder that starts with the first letter of the ticker, then finds the ticker symbol (another folder contained by the "first letter" folder), then finds the specified file. The file starts like this: Date PriceMPR_ME_DR 7/2/2012 0.07620689655172411 7/3/2012 0.2241379310344821 7/5/2012 0.31724137931034396 .... The data column is plotted just like any other indicator, except that it might take longer to load 40 years of data than to compute a simple indicator. Most of the indicators I use are custom computations, so I can't live without this feature!
