Roger Hunter introduced me into his network, as you are. We are in the process of revamping , streamlining, lowering customer cost so as the subtitle ‘Stay Tuned” will be replaced by the new line.
I have added your July show to our upcoming events on the ‘Order Here’ page. If you object to this please let us know.
Sincerely, John Topper, President Tradeworx Products®
