The ROE Bars have three different inputs: range, ticks, and seconds. Each input can be in one of four states: [1] disabled, [2] minimum value only, [3] maximum value only, or [4] both a minimum and a maximum value. 

Range – Setting a minimum range forces each bar to be at least N ticks (high – low), eliminating smaller bars. Setting a maximum range ensures that would-be massive bars (made during very fast moves) are broken up into separate bars which helps to more quickly identify when that fast move may be losing steam. 

Ticks – Setting a minimum number of ticks ensures that each bar has a more even distribution of volume while also setting a maximum number of ticks allows for variation between the bars so that huge spikes in volume entering the market are more easily identifiable and signaled on the chart.

Seconds – Setting a minimum number of seconds helps to eliminate what would typically be bursts of tick-chart bars built from large amounts of volume pouring into the market, thereby allowing for better volume signals. Settings a maximum number of seconds ensures a more even distribution of bars over time without the odd-looking thin-volume bars during the overnight sessions.
