I would love to be a fly on the wall in those chat rooms it facilitates..



99% of it is:

  where do u see 5y5y
  size?
  20k
  2.4456/2.4511
  tx


Explanation/translation for those of us that don't understand?


A trader has an idea about what inflation will look like in 2025-2030 (The 5 Year period starting 5 years from now).

Lots of other people have ideas about the same thing, so there is a product you can buy or sell to bet on it.

She asks her broker what price they can buy or sell it. The broker asks how much she wants and gives a price.

This conversation is so common that there is an agreed upon structure for it. Bloomberg parses all your conversations and provides you with an aggregated view of all quotes brokers have offered you. You can then chart/do whatever you want with this data.

I appreciate when a human interaction becomes so formalized that it becomes a de-facto API that computers can use. It would be funny to imagine a future where that interaction is happening between 2 chatbots and report results back to their humans.


That's actually what is happening a lot of the time. The humans are just monitoring and stepping in when needed or when they get bored.


former trader here. did indeed write a parser based on simple regex to read in these price quotes for our custom pricing tool. :)


Person A: where do u see 5y5y = where is XYZ financial instrument trading? (in this case, a 5y5y forward swap, I'm guessing)

B: size? = how much do you want to buy or sell?

A: 20k = $20,000

B: 2.4456/2.4511 = bid/offer = price/rate that A can sell/buy at

A: tx


One amendment: 20k means dollars per basis point, rather than dollars of notional. That is, enough notional that a 0.01% change in interest rates would cause a $20 000 change in the net present value of the instrument. Traders often think in these terms because it makes it much easier to compare across different instruments.

Also, if you tried to trade 20k dollars notional, dealers would tell you to get lost, because an amount that tiny isn't worth their time.


also known as DV01 https://en.wikipedia.org/wiki/Bond_duration#Dollar_duration,...

traded like this because it is a meaningful measure of risk regardless of tenor. also its the same whether you're doing bonds or interest rate swaps (or, rarer, options)


Thanks, $20k seemed exceedingly low on a notional basis but I'm obviously not familiar with that market.


and if that 2.* header is stable enough brokers often drop it because they're lazy AF


It is exactly as exciting as anyone would find a ChatOps Slack channel. Maybe less so.


The size matters because the bid-ask spread will be different based on the size, due to factors like liquidity, volatility, order book, etc.


For those unfamiliar with the terminal (to be fair to BB), there is a whole lot of functionality other than the chat.


The chat rooms have really interesting features, like pinning and rich-embedding equity information that updates in real time. Also, you can "ring" the room with a bell, which was immensely entertaining as an intern.


Ringing the bell is grounds for expulsion from many chat rooms, at least the semi-anonymous chat rooms provided by Bloomberg and other sell sides shops. Apparently it is very annoying to certain people.


What are the valid uses for the ring?


If you give a quote as a trader you typically give the other participant some time to answer you.

If the price moves against you since you last quoted, you typically say something like "off" and ring the bell so that the other guy knows that price is not good anymore. Fairly relevant when you're talking to a salesguy who is not looking at the chat, cause he's talking with his trader


Good question. I think of it as being equivalent to marking an email “high priority”. In my experience brokers would sometimes use it to call attention to a time-sensitive issue, eg confirming details for a trade settling today. Always thought it was annoying and if they had something really urgent they should just pick up the phone, but that’s just me.


Not surprised. A few interns were able to crash IB one year by spamming a chat with timed bells.


Now I'm remembering the MSN 'nudge' feature...


Remember not to commit securities fraud in writing. A lot of people make that mistake.


A useful more advanced tip: don't put in writing that you're taking the conversation offline to avoid putting securities fraud in writing.


Echoing another commenter, level of discourse is generally pretty low. In public chat rooms you’re more likely to get a wise crack rather than an actual response to any question. That said, you can still find some nuggets of wisdom.
