tv-account-switch

name	tv-account-switch
description	Switch between TradingView paper portfolios reliably using DOM index-click (NOT text-match, which has substring collisions on this user's account names). Verifies the post-switch account name, handles the dropdown's between-call auto-close, and warns when the user has manually clicked into a different account. Aliases — tv-switch, tv-account, tv-pick-acct.

tv-account-switch

MCP server: tradesdontlie/tradingview-mcp — the mcp__tradingview-desktop__* tool family.

The user has ~13 paper portfolios with overlapping name substrings (HIGHFWWRABV55_SCOREABOVE50, …_V2, …_V3, …_V4). Text-match clicks pick the wrong row. Use DOM index instead.

When to use

• Any workflow that operates on a specific paper account.
• After tv-cdp-launch returned green.
• Before reading positions, placing trades, or closing positions.

Hard rules

1. Never assume the current account. Read span.accountName-dm1wtgNn before AND after every switch.
2. Never trust text-match for the click. Use index from a freshly-enumerated dropdown.
3. Two MCP eval calls do not share dropdown state. Each ui_evaluate is a fresh Runtime context; the dropdown auto-closes when focus shifts. Sequence: enumerate-in-one-eval → click-in-next-eval. Don't insert a third eval between them.
4. The user can switch the account manually. After any user message, re-verify before trading.

Step 1 — Install helpers (once per page load)

mcp__tradingview-desktop__ui_evaluate(expression=`(function(){
  window.__curAcct = function(){
    return document.querySelector('span.accountName-dm1wtgNn')?.textContent.trim() || '';
  };
  // The dropdown opens ONLY on a full pointer-event sequence — a bare
  // .click() stopped working on TV 3.1.0.7818 (verified 2026-05-17).
  window.__openDD = function(){
    var b = document.querySelector('button.dropdownButton-dm1wtgNn');
    if (!b) return 'nobtn';
    var r = b.getBoundingClientRect(), cx = r.left+r.width/2, cy = r.top+r.height/2;
    ['pointerover','pointerdown','mousedown','pointerup','mouseup','click'].forEach(function(t){
      var ev = t.indexOf('pointer')===0
        ? new PointerEvent(t,{bubbles:true,cancelable:true,clientX:cx,clientY:cy,pointerId:1})
        : new MouseEvent(t,{bubbles:true,cancelable:true,clientX:cx,clientY:cy});
      b.dispatchEvent(ev);
    });
    return 'opened';
  };
  // Account-row class is a rotating hash (RDCgMoEQ -> fY6nuScj on 3.1.0.7818).
  // Match hash-agnostically so the skill survives the next TV version bump.
  window.__acctRowSel = 'div[class*="middle-"][class*="hasTitle-"]';
  window.__listAccts = function(){
    var divs = document.querySelectorAll(window.__acctRowSel);
    var out = [];
    divs.forEach((d,i)=>out.push({i, txt: d.textContent.trim()}));
    return out;
  };
  window.__pickIdx = function(idx){
    var divs = document.querySelectorAll(window.__acctRowSel);
    if (idx >= divs.length) return 'oob:' + divs.length;
    divs[idx].click();
    return 'clicked:' + divs[idx].textContent.trim();
  };
  return 'helpers ready';
})()`)

Selector note (2026-05-17): TV rotates the hashed CSS class on the account rows — it was div.middle-RDCgMoEQ.hasTitle-RDCgMoEQ, now div.middle-fY6nuScj.hasTitle-fY6nuScj on 3.1.0.7818. The helpers above match div[class*="middle-"][class*="hasTitle-"] so they do not break on the next bump. Also: the dropdown no longer opens on a bare .click() — __openDD dispatches the full pointerdown→mousedown→mouseup→click sequence.

Step 2 — Enumerate accounts

Open the dropdown and read the row list. The dropdown closes between MCP calls, so the read must be the very next eval.

Call 1 (use the __openDD helper — bare .click() no longer opens it):

ui_evaluate(expression=`window.__openDD()`)

Call 2 (immediately after):

ui_evaluate(expression=`(function(){var d=document.querySelectorAll('div[class*="middle-"][class*="hasTitle-"]');return JSON.stringify(Array.from(d).map((x,i)=>({i, txt:x.textContent.trim()})));})()`)

You get something like:

[{"i":0,"txt":"HIGHFWWRABV55_SCOREABOVE50_V3"},
 {"i":1,"txt":"HIGHFWWRABV55_SCOREABOVE50_V2"},
 {"i":2,"txt":"_MANUALBROKIE_CONV_TRUST6p4"},
 {"i":3,"txt":"__VERIFIEDALPHA"},
 ...
 {"i":10,"txt":"The Leap CryptoTradingView"},
 ...]

The last row is Create account… — skip it. The Leap Crypto is a TV-native account with a badge appended (TradingView) — also skip unless explicitly requested.

Watch for invisible prefix differences. _MANUALBROKIE_CONV_TRUST6p4 has ONE underscore; __VERIFIEDALPHA has TWO. The user's reminder list often types both as __… — trust the DOM enumeration, not the user's message.

Step 3 — Click by index

Re-open + click in two sequential calls. Do not insert any other call between — the dropdown will close.

Call 1:

ui_evaluate(expression=`window.__openDD()`)

Call 2 (or just window.__pickIdx(8) if helpers are installed):

ui_evaluate(expression=`(function(){var d=document.querySelectorAll('div[class*="middle-"][class*="hasTitle-"]');d[8].click();return 'clicked:'+d[8].textContent.trim();})()`)

Expected return: clicked:<target name>. If you get Cannot read properties of undefined (reading 'click'), the dropdown closed between calls — retry.

Step 4 — Wait + verify (MANDATORY)

sleep 4    # account-switch animation + table refresh

ui_evaluate(expression=`document.querySelector('span.accountName-dm1wtgNn')?.textContent.trim()`)

The returned string MUST equal the target. If not, repeat Step 3. Never proceed to position reads, trades, or closes without this match.

Step 5 — Trade or read

You can now call tv-positions-read, tv-paper-trade, or tv-close-positions for this account.

Anti-patterns (do NOT do these)

Anti-pattern	Why it fails
ui_click(by="text", value="HIGHFWWRABV55_SCOREABOVE50_V3")	Matches the first row containing that substring — picks V2 or V4 if listed first
Single eval that opens dropdown, waits 500ms, then clicks	The Promise/setTimeout return value isn't awaited by MCP; result {}
Skipping the post-switch verify	Account-drift causes trades on the wrong portfolio (production outage 2026-05-09 — feedback_tv_cdp_orchestrator_lessons_2026-05-09.md)
Hard-coding indexes from memory	Order shifts when user adds/removes accounts. Always re-enumerate before clicking
