The renko always seems to have a consistent angle to the up or down movements.
Put the MT Trend Slope Analysis on lets you peep inside the renko brick.
A visual slowing down and divergence is a great way to see weakness in the renko direction.

I have put together some templates and workspaces - altered for a bit more simplicity on the the website which can be downloaded from
http://www.micro-trends.co.uk/ninjatrader-downloads/

The chart template is called:

MT Range Trader TTF Renko 4 Div

Used as part of the MT HI LO trading system I use this chart to get into trades ealier than a 10min or 987 tick will let me in.
I combine other levels with the setup but look to the renko to get me in.
