📰 The News Desk: Margin Call

Same ten headlines, same six stocks — but the trading engine underneath now runs on real market mechanics: risk-based margin, bid-ask spreads, transaction costs, the ability to WRITE options (not just buy them), and genuine margin calls with a one-round grace period before forced liquidation. Reading the news right is still necessary. It's no longer sufficient.

How This Works

💰 Starting Capital

₹50,00,000 in cash. Every trade now carries a bid-ask spread and real transaction costs (brokerage + statutory charges).

📈 Six Stocks

RELIANCE, TCS, HDFCBANK, TATAMOTORS, SUNPHARMA, ADANIENT — real sectors, real behaviour under news.

🎯 Three Instruments, Two Sides

Spot (own the share), Futures (long or short, risk-based margin), Options — now BUY or WRITE calls/puts. Writing earns premium upfront but blocks margin and carries real (for calls, uncapped) risk.

🚨 Margin Calls

Risk-based margin (higher-IV stocks cost more). If your available capital falls short, you get ONE round's warning to fix it — then your worst-performing leveraged position is force-liquidated, with a penalty.

📰 Ten Rounds

Each round: a real-style headline, then you trade at the CURRENT price — before the market has actually moved.

🤖 Momentum Bot

Goes long whatever rose ≥1.0% last round, SHORTS whatever fell ≥1.0%, sizes bigger into stronger signals — scaled down on the riskiest (highest-IV) names, and cut in half after a real drawdown, like an actual risk desk would. No news reading, no emotion.

📰 News-Reader Bot

Trades the SAME round's headline immediately, using plain sector/company logic (a rate cut helps banks, a GST cut helps autos, a company's own news hits that company) — and backs each call with real conviction, sized the way a confident derivatives trader would. Right on 9 of the 10 rounds, with the leverage to make that correctness pay. Wrong in exactly the way a hasty reader would be — and that one round costs it too.

↩️ Mean-Reversion Bot

Fades the crowd: any stock that moved more than 3% in a single round gets bet AGAINST the next round, on the assumption sharp moves partly snap back. Wins on overreactions, loses on genuine trend changes.

😱 Panic Bot

Reacts to every headline's surface mood instantly — a decent gut instinct, about as often right as wrong is costly — but has zero holding discipline: closes out and re-enters a fresh leveraged bet EVERY round, paying real spread and slippage each time. The churn alone is enough to turn an OK read into a steady loss.

🧠 Instrument-Smart Bot

Reads the news exactly like the News-Reader Bot — same calls, same conviction — but trades every round through the REAL instrument engine: actual Black-Scholes premiums, real bid-ask spreads, real risk-based margin. It closes out and re-opens fresh each round like the Panic Bot does, except it picks the instrument that fits the headline: a bought option on a genuine surprise, futures when conviction is moderate or the stock's too expensive to option, defined risk whenever the "obvious" read could be a trap. Same read as News-Reader. Different bill.

📊 Benchmark

An equal-weight buy-and-hold portfolio, built once at Round 1 and never touched again — the "did nothing" baseline.

⚠️ Not every headline means what it sounds like. Some rounds have second-order effects — read past the first sentence.
