The “Open in LootX” button takes a user from your service straight into the trading terminal: the right coin, exchange, and market, the right panel — all with one click. Technically, it’s just a regular link with the lootx:// scheme. No API keys, registration, or server-side work on your end is needed.

How it works

Quick start

lootx://open/instrument?t=BINANCE:BTCUSDT.P&src=myscreener

<a class="open-in-lootx"
   href="lootx://open/instrument?t=BINANCE:BTCUSDT.P&amp;src=myscreener">
  Open in LootX
</a>

type Props = { exchange: string; symbol: string; perp?: boolean };

export function OpenInLootX({ exchange, symbol, perp = true }: Props) {
  const t = `${exchange}:${symbol}${perp ? ".P" : ""}`;
  const query = new URLSearchParams({ t, src: "myscreener" });
  return <a href={`lootx://open/instrument?${query}`}>Open in LootX</a>;
}

// One function for all commands: values are encoded, src is always added.
export function lootxLink(command, params = {}) {
  const query = new URLSearchParams({ ...params, src: "myscreener" });
  return `lootx://${command}?${query}`;
}

lootxLink("open/instrument", { t: "BYBIT:SOLUSDT.P" });
// → lootx://open/instrument?t=BYBIT%3ASOLUSDT.P&src=myscreener

Try it right from here:

Ready-made links

• Open a futures contract in the active panel
  lootx://open/instrument?t=BYBIT:SOLUSDT.P&src=myapp
• Open spot
  lootx://open/instrument?t=BINANCE:ETHUSDT&src=myapp
• Show the coin on all exchanges in a new window
  lootx://open/all-exchanges?s=SOLUSDT&target=window&src=myapp
• Open a chart in a new window
  lootx://open/panel?layout=chart&t=OKX:ETHUSDT.P&target=window&src=myapp
• Send the coin to link group 3
  lootx://open/instrument?t=OKX:ETHUSDT.P&link=3&target=group&src=myapp
• Open a coin and immediately mark a level
  lootx://open/instrument?t=BINANCE:BTCUSDT.P&level=64821.5&src=myapp
• Mark a level
  lootx://level/set?t=BINANCE:BTCUSDT.P&price=64821.5&src=myapp
• Clear your levels (0.6.53+)
  lootx://level/clear?t=BINANCE:BTCUSDT.P&src=myapp

All commands and parameters are in the lootx:// links reference.

Levels from your service

A liquidity wall screener or signal service can mark important prices in the terminal. level/set places a horizontal level on a coin, and level/clear removes it.

Starting with version 0.6.53, each level is tagged with your src: the time and sales labels the line with the service name, and level/clear removes only your levels — manually drawn ones and those placed by other services stay in place. This lets you safely update drawings: first clear your levels, then place new ones.

How to invoke the link correctly

• From the page’s main window. From an iframe with the sandbox attribute, the browser won’t open the link. If your widget is embedded on other sites, open the link in the top window.
• Encode the values. Build the link with URLSearchParams or encodeURIComponent. Values may contain Latin letters, digits, and _ . : -; the entire link is up to 1500 characters.
• Show a fallback. You can’t reliably detect from the browser whether the terminal is installed. Open the link right away, and after a few seconds unobtrusively offer help.

openButton.addEventListener("click", () => {
  location.href = lootxLink("open/instrument", { t: "BINANCE:BTCUSDT.P" });

  // Not "terminal is not installed", but a hint in case nothing happened.
  setTimeout(() => {
    hint.textContent = "Nothing opened? Install LootX for Windows.";
    hint.hidden = false;
  }, 3000);
});
