open-trade-bot

A minimal, open-source trading bot built on the Picckles Signals API — a read-only REST API for stock trading signals. Next.js (App Router) + TypeScript, deployable to Vercel with a daily cron.

Free to try, no scraping, no backtesting your own strategy required: the API tells you what to buy and when to sell, this bot wires that into a runnable loop with a live dashboard. Ships in paper-trading mode so you can see it work with zero broker setup — one function (placeOrder, in src/lib/bot.ts) to swap in for real orders.

What it does

Each tick (GET /api/run, hit by Vercel Cron or your own scheduler):

Checks the API for SELL/HOLD decisions on any position it's currently holding, and paper-sells the SELLs.

Checks the API for today's BUY signals, sized to your per-trade budget, and paper-buys anything new.

Persists positions and a trade ledger to Upstash Redis.

The dashboard (/) shows open positions and recent trades, and has a Run now button to trigger a tick manually — handy for trying it out without waiting for the cron.

Quickstart

cd open-trade-bot<br>npm install

cp .env.example .env.local<br># - get a free API key: https://picckles.com/api-pricing<br># - get a free Upstash Redis (needed for positions to persist): https://upstash.com

npm run dev">git clone this-repo><br>cd open-trade-bot<br>npm install

cp .env.example .env.local<br># - get a free API key: https://picckles.com/api-pricing<br># - get a free Upstash Redis (needed for positions to persist): https://upstash.com

npm run dev

Open localhost:3000, click Run now .

Deploying

Push to GitHub, import into Vercel.

Add the env vars from .env.example in the Vercel project settings (PICCKLES_API_KEY, UPSTASH_REDIS_REST_URL/_TOKEN, and a random CRON_SECRET).

vercel.json already schedules /api/run for 21:05 UTC on weekdays (shortly after the US close) — adjust the cron expression if you want a different time.

Strategies

Set STRATEGY in your env to either:

Strategy<br>Style<br>Typical hold

double7-guarded (default)<br>Buy a strong uptrend on a short-term low, VIX crash gate<br>~2–3 weeks

rs-pullback<br>Buy a relative-strength leader on a fast capitulation dip<br>~2–5 days

Full entry/exit rules: picckles.com/api-docs#strategies.

Going live

Everything routes through runTick() in src/lib/bot.ts, which currently only calls logTrade() (paper). Add a real broker call (Alpaca, Interactive Brokers, etc.) alongside it and the rest of the bot — signal fetching, exit checks, position tracking — is unchanged.

Disclaimer

Signals are informational only and identical for every API subscriber — not personalized investment advice. This bot trades paper money by default; you are responsible for anything you connect to a real broker.
