Appearance & colors

Settings ▸ Appearance controls how Nocterm looks: the overall theme and the chart palette. Pick a light or dark theme, then tune the colors of the chart itself - either from a preset or by setting custom colors per surface.

Overview

There are two parts. The theme sets the whole interface to Light, Dark, or Auto, where Auto follows your system preference. The chart palette governs the colors drawn on the chart, organized by surface - candles, indicators, heatmap, and bid/ask - with a role for each part of a surface (for example the up and down colors of candles, or the bid and ask sides). You can start from a preset and leave it there, or override individual surfaces with custom colors.

How to use

1. Open Settings ▸ Appearance.

2. Choose your theme - Light, Dark, or Auto.

Tip

Set the theme first, then the palette - some preset palettes are tuned for a dark or light background, so the theme choice changes how a preset reads.

Time zone

The Time zone setting puts every timestamp in the terminal - chart axis, crosshair, tape, blotter, bot logs - in the zone of your choice: UTC, this machine’s Local zone, or a fixed market city (New York, London, Tokyo, and other major venues; DST is handled correctly). It also moves the trading-day boundary: session volume profiles bucket on the selected zone’s midnight, and bot daily-loss ledgers roll there too. Dates you type (replay ranges, backtest windows) are read in the same zone, so what you enter always means what you see.
