The midterms are four days away, and the results could have a real impact on the markets.
Follow and trade the outcomes of key Senate, House, and governor races on Public.

When IV is high, so is option pricing, and so is the cost of being wrong on size.
On the @Public API, you can pull IV and all five Greeks for up to 250 contracts in one request, add up your book’s vega, and send a 6-leg order, all from your own code.
Volatility is the market’s price for uncertainty. When it moves, everything else gets repriced: option premiums, position sizes, stop distances, hedge ratios.
If you trade through the @Public API, you can measure volatility, take a view on it and manage your exposure to it, all from your own code. You set every parameter.
Measure it
• Pull historical equity and options bars and calculate realized volatility your own way
• Pull real-time implied volatility and Greeks for up to 250 contracts per request
• Compare implied with realized to see whether options look rich or cheap by your measure
Trade it
• Multi-leg orders with up to 6 legs, so straddles, strangles, spreads and condors go out as a single order
• Options limit orders up to $500K notional
Know your exposure
• Delta, gamma, theta, vega and rho come back on every option quote under optionDetails.greeks
• Add them up across your book to see your net delta and vega before you add more risk
Define your exits
• Bracket and OTO orders with take-profits and stop-losses
• Trailing stops that follow the price by a dollar amount or a percentage
• Replace order lets you change a price or size without canceling first
Know before you send
• Preflight checks an order against the limits before you submit it
• orderId deduplication means a retry after a timeout never creates a duplicate order
Pretty amazing what you can build on APIs now- I can run a full desk across equities, ODTE, and futures on my phone

the ultimate order type
New on the Public API: Trailing stop loss orders.
Set a trailing amount or percentage, and your stop price automatically adjusts as the market moves in your favor.

Many have been asking - I’m really excited about this for options traders. You can now trail brackets and oco by amount or percentage- huge unlock..how would you use these in your setup?

If you’re building order logic for size on the @public API, these are the limits to plan around:
Don’t hardcode tick sizes or precision. Option price increments and per-symbol crypto precision come from the instruments endpoint
Limits are enforced when an order is placed. Run orders through the preflight endpoint first so your system catches a rejection before it happens

Your backtest could have a lookahead bug.
If you pull bars mid-session, the final bar is still forming. Drop it before computing signals, or your results are using data that didn’t exist yet.
Historical equity and options data are free on the @Public API:
