Performance tips

Nocterm runs entirely in your browser, drawing live charts, overlays, and order flow in real time. That’s flexible, but it also means the terminal shares your machine’s CPU, GPU, and memory with everything else the browser is doing. On a fast machine you’ll rarely notice; on a slower one, a few habits keep things smooth. This page collects the practical ones.

A multi-panel layout with several heavy overlays running at once

What costs the most

Section titled “What costs the most”

The heaviest things to draw are the real-time overlays - each one redraws as the market moves:

  • Liquidity heatmap - paints resting depth across every price level.
  • Footprint - per-price buy/sell cells inside every candle.
  • Order-flow field and other flow overlays - continuously updated bands.

Running several of these on the same chart, across several panels, is where most slowdowns come from.

Practical tips

Section titled “Practical tips”
  • Limit heavy overlays per chart. Keep the liquidity heatmap, footprint, and order-flow field to the one or two that you’re actually reading. Turn the rest off rather than leaving them on out of habit.
  • Run fewer panels on slower machines. Each extra panel is another live chart redrawing. Trim the layout to the panels you’re trading from.
  • Close what you’re not watching. Overlays and panels you’ve finished with still cost draw time - switch them off.
  • Use a modern browser. A current, up-to-date browser draws charts faster and more efficiently. Keep it updated.
  • Give it adequate RAM. Live order flow holds a lot of data in memory. Closing unrelated heavy tabs frees room for the terminal.
  • Watch the multiplier effect. Heavy overlays multiply with panels - three flow overlays across four panels is twelve live redraws. Cut either factor and it gets lighter fast.
