To put that into context, the original pricing was £35 per meeting, so it's really cheap compared to that. The commercial license fees are way higher as well.
Just choose the lowest priced subscription and have a play.
Opinions on TPD - is it worthwhile?
There still seems to be very little information or examples available generally about TPD and the ways in that it can be used. I've been dabbling with automated IR on the UK horseracing markets over the past month (having previously spent many years trading IR profitably back in the day) and to the naked eye it seems to be tied-down pretty tightly with regards to price moves and the eventual result. Has it become a battle of who has the sharpest analytical mind and/or automated routines? I'm interested to see what it can do but my question is how long does it take to get to grips with the functionality and how many have tried and succeeded implementing automated strategies versus how many have tried and failed to create anything vaguely profitable?
