Thanks Brad, I'll follow up.
By the way, good luck with figuring out your pricing model. This board
has some very competent folks (sometimes a bit grumpy but I guess that
happens if you are at the top of your trade) that have said they'll
pay for your product if you bend a bit -- a high class problem!
One other suggestion: the way your products stand today, they appeal
to the 10% out there who are experienced traders. If you build a
system or two around your indicators, I think you will increase your
sales as you tap into the 90% who have no clue about Ehlers. Not sure,
but something to think about.
