Dynamic fill space: keeps a constant percentage of empty space to the right of the last bar
Fill Space automatically maintains a constant percentage of empty space to the right of the last bar on your Sierra Chart, regardless of how much you zoom, scroll, or resize the chart window.
Sierra Chart's built-in fill space setting is a fixed number of bars. That sounds fine until you zoom in, but suddenly the empty area takes over half the screen. Or you zoom out and the latest bar is glued to the right edge. Either way, you end up reaching for the fill space input again and again. Fill Space removes that friction by treating fill space as a target percentage of the visible chart area and adjusting the bar count in real time as you interact with the chart.
It's a small, silent quality-of-life study with zero configuration, zero performance impact, running invisibly in the background.
After purchase (free), Fill Space is added to your Sierra Chart account automatically. Restart Sierra Chart, then add the study to any chart via Analysis → Studies → Add Custom Study → Fill Space. Set the Fill Space % input to your preferred ratio (20 is a comfortable default for most layouts).
At runtime, the study reads the current number of visible bars on the chart, calculates how many bars should be empty on the right side to hit the target percentage, compares that to Sierra Chart's current fill space value, and updates it only if the difference exceeds the ±1 bar deadband. The update happens transparently as part of the normal chart redraw cycle, with no flicker, no jitter, and no performance hit.
When you zoom in, the visible bar count drops and the study reduces the fill space proportionally. When you zoom out, it expands the fill space. The visual ratio stays constant whether you're looking at 50 bars or 500.
