Auto paper-trade the top 5 daily EXTREME flows
A hands-off way to backtest "follow the unusual flow": every morning, pull the day's highest-scoring EXTREME options prints from RadarPulse and open matching positions in your free $100K paper-trading wallet. No real money, no broker, just a clean, automated experiment in whether the strongest scored flow is worth following.
What it does. Calls the RadarPulse flow API, keeps only prints flagged EXTREME (score 85+), takes the top 5 by score, and submits each as a paper trade. Run it on a daily schedule and your paper wallet becomes a running record of how the day's most unusual flow plays out.
Prerequisites
- A RadarPulse account with API access (in private beta, join the waitlist) and an API key.
- Node.js 18+ (the example below) or Python, both work the same way against the REST API.
- A scheduler: cron, a scheduled GitHub Action, Railway, Replit, or Val Town.
- Flow tiering: real-time tape is Elite; 15-minute-delayed flow works on lower tiers and is fine for a once-a-day run.
The script
Illustrative Node example against the RadarPulse API beta. Set RADARPULSE_API_KEY in your environment.
// auto-paper-trade.mjs, open paper trades on the day's top EXTREME flows
const KEY = process.env.RADARPULSE_API_KEY;
const BASE = "https://api.radarpulse.io"; // API beta base
const TOP_N = 5;
async function main() {
// 1) Pull recent scored flow (min score 85 = EXTREME)
const res = await fetch(`${BASE}/api/v1/flow?minScore=85&limit=200`, {
headers: { "x-api-key": KEY }
});
if (!res.ok) throw new Error(`flow ${res.status}`);
const { data } = await res.json();
// 2) De-dupe by ticker, keep the highest-scoring print per name, take top N
const best = new Map();
for (const p of data) {
const cur = best.get(p.ticker);
if (!cur || p.score > cur.score) best.set(p.ticker, p);
}
const picks = [...best.values()].sort((a, b) => b.score - a.score).slice(0, TOP_N);
// 3) Open a paper position matching each print's direction
for (const p of picks) {
const order = {
ticker: p.ticker,
side: p.type, // CALL or PUT, mirror the flow
strike: p.strike,
expiry: p.expiry, // ISO date from the API
qty: 1,
note: `auto: EXTREME score ${p.score} (${p.bias})`
};
const r = await fetch(`${BASE}/api/paper/submit`, {
method: "POST",
headers: { "x-api-key": KEY, "Content-Type": "application/json" },
body: JSON.stringify(order)
});
console.log(p.ticker, p.type, "score", p.score, "→", r.status);
}
}
main().catch(e => { console.error(e); process.exit(1); });Endpoints shown (/api/v1/flow, /api/paper/submit) are part of the RadarPulse API beta. Field names are illustrative, the live API reference ships with your beta key.
How to run it
RADARPULSE_API_KEY, adjust TOP_N if you want more or fewer names.Risk & responsibility. This opens paper positions only, simulated, no real money, no broker. Unusual options prints are not buy or sell signals and can reflect hedging or spreads; "follow the EXTREME flow" is an experiment, not financial advice. You are responsible for any script you run and for respecting API rate limits. Keep your API key secret. Trading and investing involve substantial risk of loss.
