Hi thank you Tomasz for implementing range bars.Since they are in the beta status please allow me some remarks:
Range bars are "meant to be" constant range bars. In order to make it robust one has to set the range, and that range has to be predicted from the future and we know that this is impossible to be 100 % accurate. You will never know exact range needed for bars to be constant ( unsplitted or whatever one calls it ). That also applies for ticks data. I think the misunderstanding comes from the fact that Tomasz has to convert/translate TIME bars into RANGE bars. Better will be to think in therms in coverting pure PRICE range to CONSTANT range. Sort of Renko philosophy or Tick bars. In the end why not let the user choose to unsplitt or split range bars // of course if not too much code intensive//.

The point is that you can not say for sure that the pattern really occurred if range of 4 happened inside one 1-minute bar. You don't know if it was 4 up bars and then 1 down. It could be 2 up bars, 1 down and 3 up. Or 1 up, 1 down and 4 up. Or thousands of other combinations. You don't know. That's the point. You can not rely trading on something that is based on wild guesses and those guesses are mostly wrong. More info in my previous response that you have removed from the reply: http://finance.groups.yahoo.com/group/amibroker/message/113212 That's why I say: use *tick data* to create range bars or use ranges that are larger than any 1-minute movement. The same advice you will find in any software that support range bars.
