A person I know was using it as bands.(not sure he's still using it)
It was used for daytrading ER2.
One LRI based on high and the other one based on lows.
The period was very short, I think 5.
It was generating signals but missing the action if market was up or down fast from the open.
Instead of trying to fix that flaw I decided to try something else
the was not missing any fast major bull or bear action from
the open.
