Spread Trading Game v1.8.1

Spread Trading Game 1.8.1

A single-player roguelite about trading options spreads on real historical market data, now with a Trade Builder for today's market. Paper trading only; not financial advice.

What's new in 1.8.1

• 50 tickers in all, as you meant: the game's 25 plus the 25 added in 1.7.0. 1.8.0's second 25 (EEM through RDDT) are gone from the Trade Builder and from PULL FROM SCHWAB, so a pull is shorter. Anything already saved for them on your PC is left alone and never used.
• Index options in the Trade Builder: SPX, XSP (a tenth of SPX, sized for small accounts), NDX and RUT, in their own group under ALL. Type SPX or $SPX. They load live from Schwab like any ticker (PULL FROM SCHWAB saves them too), and the order ticket marks them CASH-SETTLED: European style, no early assignment, no shares at expiration. Their chains are huge, so the builder asks Schwab for the strikes nearest the money and narrows the request if Schwab turns it down. Where SPX lists two contracts on the same strike and day (the AM-settled monthly and the PM-settled weekly), the builder keeps the PM one.
• Fix: BUILD GAME DATA FROM SCHWAB had started sweeping the Trade Builder's extra tickers into the game's own market (since 1.7.0). Career lineups deal only the game's tickers again. If you built game data from Schwab since 1.7.0, build it once more.
• A new test checklist (Settings › Game › Developer mode, then DEV › TEST CHECKLIST): only what changed since 1.6, each check tagged with its release. ▶ SET UP takes you straight to the spot (the Trade Builder at a ticker or a LEARN OPTIONS lesson, a run with the boss or rules it needs, the tutorial from the start, Settings › Data), and SAVE AS FILE writes one file with every result, note and playtest note, stamped with the version.
• Fixes: a LEARN OPTIONS task done in its first instant now shows its ✓; when days run fast, yesterday's recap leaves before today's arrives (two no longer stack); odd contracts (adjusted after a split, minis) no longer slip into a Schwab chain; the ticker list no longer has the chart's tabs drawn over it.

New in 1.8.0 (the Trade Builder's second version)

• LEARN OPTIONS (the amber button in the Trade Builder): a 13-lesson course on the chart you have open, from a single call to credit spreads and iron condors, then managing the trade and the events that move it. Each lesson sets up its trade for you and asks one question (explained, right or wrong) or one thing to try: move the strike and watch POP, drag DATE to expiration to see time decay, slide IV down to see vega, land a bull put at about 80% POP. Progress is saved.
• Another 25 tickers (removed again in 1.8.1: you meant 50 in all).
• Single options are named and priced as themselves ("Long call", "Short put"), with thinkorswim's single-leg order line.
• The particle effects skip a frame they can't draw instead of raising an error on computers without a graphics card.

New in 1.7.0

• The Trade Builder (replaces Live on the title screen). Open any ticker and build a real trade on today's market:
  • With Schwab connected (read-only market data), each ticker loads live: two years of daily prices and today's option chain. Without it, the newest saved data is used, and a badge says plainly how current it is (LIVE, CURRENT, or OUT OF DATE with how many trading days old).
  • 25 more tickers, the next most heavily traded option markets (QQQ, IWM, TLT, GLD, SLV, XLF, SMH, XLE, UNH, MSTR, SOFI, INTC, BABA, F, BAC, MARA, RIVN, PYPL, WMT, XOM, C, SNAP, NIO, ARM, SHOP). PULL FROM SCHWAB now fetches two years of prices for each.
  • One-click studies: Bollinger Bands, the expected move and a new 2σ line, SMA 50/200, EMA 21, Keltner Channels, support and resistance, RSI, MACD, ATR, volume.
  • Every strategy, shaped with the sliders or edited leg by leg, sized in plain contracts.
  • The payoff, full size: at expiration, today and any day before, with an IV what-if, breakevens, max profit and loss, the expected move and where the price is likely to end, a hover readout, and the trade in plain words.
  • COPY ORDER copies the order as thinkorswim-style text. Nothing is ever sent to a broker.
  • The old Live month is still there: Trade Builder → PAPER MONTH.
• Bosses: the Collector now charges daily interest (5% of a trade's risk, in points) on a losing trade left at or past a strike you sold, on its own INTEREST NOTICE; the Margin Clerk's width slider stops at your cap; the Tax Man taxes wins closed in their first week; stronger trophies (the Underwriter's is 5%, the Shell Company's takes $2 off rerolls), a bigger bounty, and bigger race charts for the Rebalancer and the Early Retiree.
• The month menu: an emblem and a name for every round, dealt in like cards. The exit plan shows what it does on a sample spread as you move it, and how your closes have gone this run; every payout is stamped with how the trade closed.
• The tutorial: what a strike is, a practice trade built past a floor or ceiling Ines marks on the real chart, the position spelled out, and a live POP bar aiming for about 80%. REROLL and SIT OUT are always in view.
• Smaller fixes: the stock's name in the chart's top-left corner; controls follow the round's rules (contract limits, no SIT OUT under the Attendance Policy); cashing out with market orders off no longer gets stuck.
