Cursor as a trading agent: PLTR RSI draft

Follow this worked strategy

I connected Cursor to the NexusTrade trading API and had it research Palantir and preview an RSI recovery draft with a $1,000 entry below RSI 30. The agent operated this workflow through NexusTrade's MCP server; it did not build the integration. The preview returns valid with an empty issues list. No historical result is recorded yet, and the first test runs only after the rules are approved.

Step 1 of 6

Connect Cursor

Add the NexusTrade server

{
  "mcpServers": {
    "nexustrade": {
      "url": "https://nexustrade.io/api/mcp"
    }
  }
}

Scroll horizontally to read the full command, or copy it.

For this project, create or open .cursor/mcp.json in the project root and merge the configuration above into its mcpServers object. For all projects, use ~/.cursor/mcp.json. Preserve other configured servers.

Sign in to your NexusTrade account

Open Cursor's Customize page to manage MCP servers. Find NexusTrade and complete the requested OAuth connection in your browser. Cursor supports OAuth for remote servers. You can also use Add to Cursor on the NexusTrade developer page and review the installed server in Customize.

What you should see

The result identifies Apple's company filing, filing date and source URL. The connection check makes no account changes.

Inspect the request

Use NexusTrade’s sec_edgar tool with action list_filings, ticker AAPL and limit 1. Report the company, filing form, filing date and source URL from the result. Use only this public read. Do not access portfolios, ingest filings, create resources or make changes. If the tool is unavailable, say so.

Step 2 of 6

Research Palantir

Open the latest company filing and date the brief before testing this price-based idea. The captured Q2 2026 filing covers the period ending June 30, 2026.

Company: Palantir (PLTR)
Filing captured: Q2 2026 10-Q; filed August 4, 2026

What you should see

A dated brief names the instrument, original sources and assumptions that matter to this strategy.

Inspect the request

Research PLTR using sec_edgar list_filings and fundamentals. Report the original filing URL, filing date, period, revenue, operating income and cash flow with units. Explain share-based compensation and customer concentration for PLTR.

PLTR RSI recovery entry and exit in the current NexusTrade strategy display — The current rule display renders this validated PLTR draft. Its historical test is pending.

Step 3 of 6

Preview the PLTR rules

Inspect the entry and exit in the native rule display. This candidate uses a $1,000 whole-share entry and a flat-position guard; the exact configuration is available with the copy request.

Execution: $10,000 initial cash; $1,000 entry; whole shares; cash dividends; manual approval

What you should see

The preview returns valid=true and an empty issues list for these rules. Saving later returns your own draft ID.

Inspect the request

Use build_portfolio to preview this exact PLTR RSI recovery configuration. Show the entry, sizing, exits, valid and issues. After I approve the rules, use create_portfolio once to save a new draft, then read it back and retain its returned ID. Keep this candidate separate from published research portfolios. Stop before submitting a paid test or deploying.

Step 4 of 6

Run the first PLTR historical test

Freeze these thresholds and choose a dated daily test before reading the result. Compare the PLTR curve with holding the same stock over matched dates.

Current status: Historical test pending
Example test plan: 2024-01-01 through 2024-12-31; daily; $10,000
Costs: 0.1% stock fee per fill; cash dividends; whole shares

What you should see

A completed test supplies its own return, drawdown, fees and order history. This new draft has no recorded historical result yet.

Inspect the request

Use the returned PLTR draft ID. Prepare one daily historical test for 2024-01-01 through 2024-12-31, $10,000, whole shares, cash dividends, a PLTR baseline and 0.1% stock fee per fill. Show the exact request and estimated cost for approval before submitting once. Poll the same returned test ID. Inspect return, drawdown, fees, history and order events. Keep thresholds fixed; do not insert 2026 filing values into the 2024 price-based rules.

Step 5 of 6

Observe PLTR RSI recovery in paper trading

Observe this PLTR candidate prospectively after reviewing its historical test. A $1,000 entry limits the amount committed per signal; the exit remains the indicator threshold shown above.

Inspect before accepting an order: The PLTR indicator value, share rounding, $1,000 entry, holding guard, exit and order approval.

What you should see

Your paper portfolio has its own ID, start date, schedule and dated history. These forward observations begin with your own run.

Inspect the request

Read back the reviewed PLTR RSI recovery draft. Prepare a separate paper-only deployment with the same rules and $10,000 starting capital. Show the plan for approval. Retain the resulting paper ID and verify its deployment type, timing, pending simulated orders and actual history. Inspect: The PLTR indicator value, share rounding, $1,000 entry, holding guard, exit and order approval. Keep the rules fixed and brokerage accounts unchanged.

Step 6 of 6

Review PLTR RSI recovery for live deployment

Review the paper candidate in Deployment Center, then choose Port to Live and inspect the actual target account before confirmation.

Open the live deployment walkthrough

Account and instrument review: Whole-share PLTR support, available buying power, evaluation timing, $1,000 entry, exit rule and manual order approval.

What you should see

The review identifies the target account, supported instruments, rule changes and approval settings before confirmation.

Inspect the request

Prepare a live deployment review for my PLTR RSI recovery paper portfolio. Read the actual account and broker capabilities, incoming rules and any existing rules that would be disabled. Check: Whole-share PLTR support, available buying power, evaluation timing, $1,000 entry, exit rule and manual order approval. Show the plan and keep live trading unchanged until I explicitly confirm it. If an instrument or action is unsupported, report it and stop.

Follow the Cursor session

This guide runs on NexusTrade's MCP server. Cursor operated the trading workflow below, from connection to the live review. The agent's role here is operating the workflow through that server.

The table names the tool call, the approval checkpoint, and the artifact to keep at each stage. Placeholders such as a returned draft ID stand for values your own run returns. This page records no IDs from anyone else's run.

No historical result is recorded for this draft yet. The filing below dates the research brief, and the first test runs only after approval.

Where Cursor stops for approval

Each consequential action in this guide waits at an approval gate. The agent previews first and acts only after explicit approval.

The rules preview returns valid and an empty issues list before anything is saved. The agent resolves problems and re-previews instead of saving a candidate with open problems.

Approve the rules before the agent saves them
The agent previews the configuration with build_portfolio and shows entry, sizing, exits, valid, and issues. It saves with create_portfolio only after approval and reads the returned draft back.
Approve the test cost before the agent submits once
Historical tests are paid runs. The agent shows the exact request and estimated cost for approval before submitting once, then polls the same returned test ID until complete.
Approve the paper plan and verify it is paper
The paper deployment is a separate portfolio with its own ID. The agent shows the plan for approval, verifies the deployment type, and leaves brokerage accounts unchanged.
Confirm the live move explicitly, or nothing moves
The agent reads the actual account and broker capabilities first and keeps live trading unchanged until explicit confirmation. It reports an unsupported instrument or action and stops.

Open the company filing

The filing dates the research brief. The proposed 2024 historical test uses price indicators; future company figures are outside those rules.
