The chap in the emini-watch.com website has the following three indicators he uses, unfortunately not free.

Better Pro AM (uses Trade Size to follow the Professionals)
Better Momentum (uses Volume to signal tops & bottoms)
Better Sine Wave (uses Price to find cycles & trends)

Anybody has suggestions of free alternative indicators that do something similar for NinjaTrader? Thanks
