Spare time? Grab a copy of <A HREF="http://www.jfholdings.pwp.blueyonder.co.uk/aim.xls" target="_blank">http://www.jfholdings.pwp.blueyonder.co.uk/aim.xls</A> An Excel spreadsheet with VBA (macro) and a Newport style hold zone calculation <img src=http://www.jfholdings.pwp.blueyonder.co.uk/aim_.gif> Add on a download price history button - perhaps something like <A HREF="http://www.gummy-stuff.org/multi-download.htm" target="_blank">http://www.gummy-stuff.org/multi-download.htm</A> and you'd have your AIM program, code, notes, data and graphs all self contained. Perhaps collaborate to Freeware/Opensource develop the spreadsheet further?
