YeScript community library inside Hyper Charts

Start in 3 steps

  1. Open Hyper Charts and click YeScript on the toolbar.
  2. Pick a template or start from scratch.
  3. Run Check, then Run to backtest a strategy.

Script types

Pick a script type by intent: strategies generate trades, indicators draw context, and libraries package reusable logic for teams.

strategy()

Simulated orders via trade.open_long / trade.open_short / trade.close_all. Browser backtest + optional server-run.

indicator()

plot(), hline(), plotshape() on overlay or dedicated sub-panes — same pane rules as built-in studies.

library()

Shared fn definitions — imported into other tabs with library("name"), never mounted on the chart directly.
