fast_eddie,
you're right. I don't know what you've been up to, but I got busy with Tech Support at QuoteTracker, helping them resolve some problems they have with their Renko charts. We've resolved some issues and have one minor problem left.
I presently know of only one canned way of generating Renko charts in Excel. The problem is it's a Visual Basic module, so you will have to be very proficient in that, which I gather you are not. I have a couple other downloads related to Renko and Excel but I haven't evaluated them yet.
Writing code to represent Renko bricks in native Excel is rather easy once you understand how Renko bricks are defined and when they stick or are erased.
Do you know how to write equations in Excel cells? Writing macros doesn't count. I've gotten the impression that you don't want to write the equations necessary to generate a Renko chart.
QuoteTracker has several schemes built in for exporting data, but I haven't determined yet what data can be exported. I'll get to that pretty soon.
