I've never heard of range charts. I'm an esignal subscriber would you mind elaborating on what they are, and what advantages they have over existing esignal charts? Thank you.
Constant Range charts are independant of time. Each bar or candle has the same range (Hi - Low). This can tend to smooth out the chart a bit. Some like 'em, some don't... eSignal also has Constant Volume charts where the volume traded of each bar is the same. For lots more info, google "constant range charts".
