Bloomberg opens the whole FX-options RFQ to code

Bloomberg’s September 14 release lets clients program the full FX-options execution sequence: request quotes, compare competing dealers and complete the trade. Coverage includes vanilla and exotic options in deliverable and non-deliverable currencies. It builds on the existing Python ticket launcher, extending automation through execution. Bloomberg announcement

This sits neatly alongside yesterday’s Optiver account of expanding direct client relationships. Optiver is widening the set of counterparties that can reach its principal book; Bloomberg is reducing the manual work a client needs to reach several dealers. Together, those developments suggest a market in which more hedging decisions can be expressed as repeatable execution policies.

The interesting discretion moves into the policy: whom to ask, how many dealers to expose the inquiry to, how long to wait, and what constitutes an acceptable response. Fast quotes are valuable, but so are consistent treatment of size, tenor and less familiar currency pairs. A client can automate an RFQ and still have a poor comparison if credit constraints or differing terms make the responses economically unequal.

Bloomberg reports FXGO options volume up more than 58% year on year since August 2025, with hedge-fund activity up more than 75%. Those figures describe the platform’s growth before this launch; they cannot establish adoption or execution benefits from the new API. No distribution of spreads, response times or transaction costs was supplied.

For banks, the competitive pressure is broader than another electronic pricing channel. Once clients encode dealer selection and acceptance rules, consistent service becomes easier to measure—and inconsistent service easier to route around. Relationships still matter, particularly for credit and complex risk, but the routine portion of the relationship becomes more contestable.

A related development after the trade: OSTTRA’s new triResolve model estimates counterparties’ FX valuation snapshot times from historical valuations and market rates. Following a four-week test with nine major firms, it is being offered to all clients. Timing differences can then be separated from genuine pricing disagreements. That should improve reconciliation triage, although the announcement supplies no independent false-positive rate or measured reduction in disputes. The Trade, September 15

Nasdaq’s order-level self-match controls arrive today

Implementation reminder: Nasdaq’s rollout is scheduled for today, following PSX on September 14 and NTX yesterday. Orders can now specify self-match prevention behavior and a group ID, overriding broader defaults; supported actions include cancelling the oldest or newest order, decrementing both, and disabling prevention. The optional fields apply to Enter and Replace messages across OUCH 5.0, CORE FIX and INET FIX. Nasdaq implementation notice, field details

The practical consequence is control over which liquidity survives when two strategies collide. Cancelling an old resting order sacrifices queue position; cancelling the incoming order may interrupt a hedge. Moving that choice to individual orders gives strategy developers more freedom, and makes centrally agreed defaults easier to override. This morning’s check is that the intended policy survives order replacement and that an omitted field behaves as expected—not merely that the new message parses.

An agent finds the assumption hidden inside a lint rule

GitHub’s September 15 ESLintRefiner report contains a satisfying, inspectable example of an agent reviewing the rules used to review code. The agent runs daily and proposes up to three nonduplicate issues about custom lint rules. One finding concerns a rule that encourages replacing Node’s child_process with @actions/exec. Developer account

The rule treated a TypeScript reference to @actions/github-script as evidence that the script would execute inside GitHub’s runtime. Some affected files also run as standalone Node programs through a shim. The shim provides certain GitHub-like globals, but not the exec object the lint suggestion assumes. Following the advice could therefore break a valid standalone execution path. Exact issue, files and proposed guard

What makes the report persuasive is its positive control: it identifies another file that should continue to be flagged after the fix. That is a much better acceptance test than suppressing warnings until the build turns green. The proposed distinction follows the runtime boundary rather than simply exempting whichever files complained.

The run reportedly used 83 turns and roughly 89,000 tokens. That is substantial effort for a lint-rule issue, and there is no cost or productivity comparison against a developer. The issue was still open when checked; I have not run the proposed repair. Even so, the artifact is useful: a concrete failure, a bounded explanation, a proposed change and a test that would catch an overbroad solution. It gives you something to inspect beyond a screenshot of an agent declaring success.

John Wilson takes his camera to the cinema

The History of Concrete opens at IFC Center on Friday, September 18. John Wilson attends a class on selling a Hallmark movie, then attempts to apply its lessons to a documentary about concrete. It is an excellent premise for someone whose curiosity tends to travel sideways. The film runs 101 minutes. IFC’s film page

Two new reviews make the choice clearer. Peter Martin’s September 15 ScreenAnarchy review finds a funny, warm-hearted film whose apparently stray encounters accumulate emotional weight. Matt Oakes, writing a day earlier, gives it a B+ but thinks some digressions stretch thinner without the tighter shape of Wilson’s television episodes. That is a useful disagreement about form: whether more time with this sensibility is a pleasure in itself, or whether the editing needs to impose a firmer limit. ScreenAnarchy, Silver Screen Riot

I would lean toward the pleasure. The combination of close observation, an absurd organizing idea and genuine interest in strangers sounds like a good cinema outing. You do not need to acquire an interest in building materials first. The caveat is the wandering: this is not a tightly plotted comedy, and the second review gives a fair reason to wonder whether the feature length occasionally exposes the seams.

The Q&As are already sold out. IFC marks all the opening-weekend discussions that way, including appearances involving Edy Modica, Rachel Kaly and Sarah Sherman. Ordinary screenings are also listed, but the ticket site blocked access before I could verify prices or selectable inventory. Keep the film, rather than the prospect of a Q&A, as the reason to check the showtimes.

Galo’s seafood rice is the reason to go

Galo, Nuno Sousa’s Portuguese restaurant at 142 West 10th Street, was scheduled to open yesterday. Its menu is now available, and it makes the earlier opening lead much more tangible. Sousa also runs Leitão; here the attraction is a broader Portuguese seafood repertoire, with petiscos and rice dishes suited to building a meal around the table. Opening guide, official menu

I would start with lingueirão à Bulhão Pato: razor clams with garlic, white wine, coriander and lemon. Then make arroz de carabineiro e lingueirão the centerpiece—scarlet prawns and razor clams in rice cooked with shellfish broth, saffron and herbs. The menu names Ariete rice from Quinta do Seminário in the Baixo Mondego. These are specific, appealing dishes, with enough substance to make a seafood dinner rather than assembling one from appetizers. Restaurant’s menu PDF

Several other seafood names conceal meat, dairy or egg ingredients. The fisherman’s stew contains ’nduja, the stuffed squid contains Ibérico pork, and the sardine-and-tomato salad includes stracciatella. Bacalhau à Brás and the shrimp ovos rotos are egg-led. The clam-and-rice route is considerably clearer; confirm the kitchen’s preparation when ordering.

The room is intended to evoke a Portuguese adega, with handmade ceramics and a design by Lisbon’s Studio Asolfi. The wine programme ranges beyond the obvious Douro choices into Bairrada, Dão and the islands. A seafood rice, a bottle and a room with some warmth is an attractive proposition for a relaxed evening. Those details come from the restaurant’s publicist, so hospitality and execution remain to be tested. Concept and design

Early-visit recommendation, with prices to check first. The published menu I could inspect was unpriced, and I could not verify reservation inventory. Wednesday and Thursday hours are listed as 4–11:30 p.m. Ask about the rice’s portion size and total price before ordering it for the table. Hours and reservations

Another West Village opening today: El Camarón Peludo

The Taqueria Ramírez team’s seafood bar is scheduled to open today, September 16, at 20 Cornelia Street, with chef Carlos Barrera. Earlier pop-ups featured michelada oysters, camarones zarandeados and tuna tostadas. That is enough to put it high on the list for an opening-menu check, especially given Giovanni Cervantes and Tania Apolinar’s work at Ramírez. Opening date, Eater’s original project report

Those pop-up dishes are not a verified opening menu. Current prices and the full pescatarian order remain unconfirmed; Galo is the one for which there is already a concrete meal to discuss.

A lavender stripe at Groupe

View original image: Seize sur Vingt Dinard lavender-and-white striped shirt

The Seize sur Vingt Dinard shirt is $160, reduced from $280, and the exact 17–35 variant was available this morning. This is a rechecked sale discovery, not a newly announced reduction. Exact shirt and size

The broad lavender-and-white stripe is what earns it a place here. It has more character than another blue office shirt, while remaining easy with cream trousers, dark denim or a navy casual jacket. Italian linen/cotton cloth gives it texture; Portuguese construction includes mother-of-pearl buttons, a split back yoke and rotated sleeves intended to improve movement. The dress collar keeps it from becoming a beach shirt.

Groupe’s SV15 cut deserves a garment-measurement comparison. Its chart gives this size a 48.5-inch garment chest, 19.75-inch shoulder and 28.75-inch length. Compare those with a shirt that already works, particularly if you want to wear this untucked. The collar and sleeve include shrink allowance. Official size chart

I would shortlist it for a fitting rather than order on optimism. Sale returns are store credit only within 14 days and require authorization; shipping is extra below the $200 US free-shipping threshold. Online stock does not establish stock at the Bowery shop. The other drawback is seasonal: this is a warm-weather shirt, even if its colours work well under autumn knitwear. At $160 the cloth and construction make a credible case, provided the cut is right.

Kyler’s status, then a Thursday trip to Buffalo

Kyler Murray remains the fantasy name to check today. He left Sunday’s Minnesota debut with a concussion; Carson Wentz took over as the Vikings scored the final 29 points to beat Green Bay 39–22. Wentz threw three touchdowns, two to Justin Jefferson. Green Bay’s defensive penalties repeatedly prolonged Minnesota drives, and Jordan Love’s late turnovers compounded the collapse. AP game report

Kevin O’Connell said Monday that Murray felt reasonably well but remained in the protocol. I could not verify a subsequent clearance. With Minnesota visiting Chicago on Sunday, today’s participation and the eventual medical clearance matter more than the reassuring wording of that first update. Vikings’ account

Tomorrow: Lions at Bills, 8:15 p.m. ET / 6:15 p.m. in Colorado, on Prime Video with a US subscription. Both teams are 1–0, and it is the first game in Buffalo’s new Highmark Stadium. Amazon’s schedule and viewing details

Detroit’s offensive line is the pregame concern. Tuesday’s report listed Christian Mahogany and Blake Miller as nonparticipants, with Juice Scruggs limited. These were estimates from walkthroughs, not three observations of a full practice. On a short week, the final availability report could materially change how comfortable Jared Goff’s evening looks. Lions’ September 15 report

BETTING — PASS. The under was the most interesting candidate to investigate: Covers projects 51.93 points against a listed 54.5 total, with DraftKings shown at −112. But the quote lacks a trustworthy timestamp, and a point forecast does not establish the probability of finishing under 54.5. At that price the required win rate is 52.8%; I have no defensible current estimate to put on the other side of the comparison. The alternative Dimers forecast also lacked sufficient input and calibration detail. No recommended entry price. Covers, Dimers

Listen: Editors, “Seriously”

Released yesterday, “Seriously” is the third single from Surface, Echo & Sound, due October 30. Start with the official lyric video.

Sonic Seducer describes ringing guitars, a driving rhythm and an ’80s new-wave streak; Tom Smith describes a warmer, more hopeful direction than the band’s dark reputation might suggest. Sounds & Books similarly hears bright, anthemic guitar-pop. Those are the critics’ descriptions, rather than a claim that I have listened. September 15 coverage, first track appraisal

The appeal is straightforward: Smith’s baritone against something with forward motion and light in it. After several more ambient and nocturnal selections, this looks like a good change of pace without requiring an album-length commitment.

Watch now: Slow Horses, season 6

“Circle of Life,” the 48-minute premiere, is available today on Apple TV in the US with a subscription. The season has six episodes, released weekly through October 21; episode two follows September 23. Watch the exact episode

Jackson Lamb investigates the death of a former Slow Horse as the series draws on two Mick Herron novels, Joe Country and Slough House. Gaby Chiappe takes over the writing, with Saul Metzstein directing the six-part run. The combination keeps the familiar question alive: how much apparent incompetence is camouflage, and how much is simply what the organization has available? Apple’s series information

Today’s Times review is strongly positive about the balance of danger and dark comedy. That is encouraging for a returning series whose pleasures depend as much on abrasive company as on the conspiracy. Season-six review

This is my choice tonight if you are caught up: one sharp, self-contained portion of the evening, with a week before the next. The two-book adaptation means plenty of plot, and season six is not a sensible entry point for a newcomer. But for returning viewers, the queue has finally become something you can press play on.
