Word has it will be out sometime in the summer. Can't wait! If you buy 2.1 now, I think you'll get the upgrade to 3.0 for free. For me and other users who bought a while back, we have to pay the $100 upgrade fee.
It's a pretty solid backtesting software. It lacks in real-time scanning capability and automated execution, which it will addresses in 3.0. So, it should be interesting to see who wins out TS vs WL? But either way, WL has a solid following and a great product IMHO.
If you purchased WLD2.1 on or after November 2002 (when WLD3.0) was announced, then you will receive a free upgrade. Otherwise the upgrade cost is $100. WLD3.0 does handle tick level charts. Release will be this Summer.
