Tyler Goodlet d62fb655eb `kraken`: parse our source asset key and set on `MktPair.src: str` 2023-05-09 14:49:25 -04:00
Tyler Goodlet a9778e4001 Always cast `Order.symbol: str` for now
To make nested `msgspec.Struct`s work we need to tell the codec that the
`.symbol` is some struct def, since we don't really need to enforce that
(yet) we're just going to enc/dec as `str` until we further formalize
and/or need something more complex.

Tyler Goodlet 0f3041724b Use `MktPair` for `Flume.symbol` when used by backend
Initial attempt at getting the sampling and shm layer to use the new mkt
info meta-data type. Draft out a potential `BackendInitMsg:
msgspec.Struct` for validating the init msg returned from the
`stream_quotes()` start value; obvs don't actually use it yet.

Tyler Goodlet 1d08ee6d01 `.clearing`: broad rename of `fqsn` -> `fqme` 2023-05-09 14:49:25 -04:00
Tyler Goodlet d4a5a3057c Add `MktPair.suffix: str` read from contract info
To be compat with the `Symbol` (for now) and generally allow for reading
the (derivative) contract specific part of the fqme. Adjust
`contract_info: list[str]` and make `src: str = ''` by default.

Tyler Goodlet 452cd7db8a Optionally load `MktPair` in `Flume`s 2023-05-09 14:49:25 -04:00
Tyler Goodlet 2cc80d53ca First stage port of `.data.feed` to `MktPair`
Add `MktPair` handling block for when a backend delivers
a `mkt_info`-field containing init msg. Adjust the original
`Symbol`-style `'symbol_info'` msg processing to do `Decimal` defaults
and convert to `MktPair` including slapping in a hacky `_atype: str`
field XD

General initial name changes to `bs_mktid` and `_fqme` throughout!

Tyler Goodlet 7eb0b1d249 Comment about `Struct.typecast()` conflict with frozen instances 2023-05-09 14:49:25 -04:00
Tyler Goodlet 589b3f4201 Default `pps.toml` precision fields to `Decimal`
For `price_tick` and `size_tick` we read in `str` and decimal-ize
and now correctly fail over to default values of the same type..
Also, always treat `bs_mktid` field as a `str` in TOML form.

Drop the strange `clears: dict` var from the loading code (not sure why
that was left in smh) and better name `toml_clears_list` for the
TOML-loaded-pre-transaction sequence.

Tyler Goodlet 6d5d9731ed Implement `MktPair.from_msg()` constructor
Handle case where `'dst'` field is just a `str` (in which case delegate to
`.from_fqme()`) as well as do `Asset` loading and use our
`Struct.copy()` to enforce type-casting to (for eg. `Decimal`s) such
that we'll now capture typing errors despite IPC transport.

Change `Symbol.tick_size` and `.lot_tick_size` defaults to decimal
for proper casting and type `MktPair.atype: str` since `msgspec` can't
cast to `AssetTypeName` without special handling..

Tyler Goodlet da10422160 `kraken`: add `Client.mkt_info()`
Allows building a `MktPair` from the backend specific `Pair` for
eventual use in the data feed layer. Also adds `Pair.price/tick_size` to
get to the expected tick precision info format.

Tyler Goodlet 72c97d4672 Handle read and write of `pps.toml` using `MktPair`
Add a logic branch for now that switches on an instance check.
Generally swap over all `Position.symbol` and `Transaction.sym` refs to
`MktPair`. Do a wholesale rename of all `.bsuid` var names to
`.bs_mktid`.
2023-05-09 14:49:25 -04:00
Tyler Goodlet 7b28c7a43f Prep for dropping `Transaction.sym`
Instead let's name it `.sys` for "system", the thing we use to conduct
the "transactions" ..

Also rename `.bsuid` -> `.bs_mktid` for "backend system market id`
which is more explicit, easier to remember and read.
2023-05-09 14:49:25 -04:00
Tyler Goodlet cf9442f4d5 Further refinement and shimming of `MktPair`
Prepping to entirely replace `Symbol`; this adds a buncha docs/comments,
better implementation for representing and parsing the FQME: "fully
qualified market endpoint".

Deatz:
- make `.src` an optional field until we figure out how we're going
  to support loading source assets from all backends sensibly..
- implement `MktPair.fqme: str` (what was previously called `fqsn`)
  using a new util func: `maybe_cons_tokens()`.
- `Symbol.brokers` and expect only `.broker` usage.
- remap anything with `fqsn` in the name to `fqme` with aliases from the
  old name.
- implement `unpack_fqme()` with `match:` syntax B)
- add `MktPair.tick_size_digits`, `.lot_size_digits`, `.fqsn`, `.key` for
  backward compat.
- make all fqme generation related fields empty `str`s by default.
- add `MktPair.resolved: bool` a flag indicating whether or not `.dst`
  is an `Asset` instance or just a string and, `.bs_mktid` the field
  to hold the "backend system market id" per broker.

a server error when requesting such info msgs.

Tyler Goodlet a44b6f7c2f `ib`: adjust to new simplified `Symbol`

Tyler Goodlet 91dda3020e Simplify `Symbol` extend `MktPair`, add `Asset`
Drop everything we can in terms of methods and attrs from `Symbol`:
- kill `.tokens()`, `.front_feed()`, `.tokens()`, `.nearest_tick()`,
  `.front_fqsn()`, instead moving logic from these methods into
  dependents (and obviously removing any usage from rest of code base,
  coming in follow up commits).
- rename `.quantize_size()` -> `.quantize()`.
- re-implement `.brokers`, `.lot_size_digits`, `.tick_size_digits` as
  `@property` methods; for the latter two, allows us to minimize to only
  accepting min tick decimal values on alternative constructor class
  methods and to drop the equivalent instance vars.
- map `_fqsn` related variable names to new and preferred `_fqme`.

We also juggle around some utility functions, moving limited precision
related `decimal.Decimal` routines to the top of module and soon-to-be
legacy `fqsn` related routines to the bottom.

`MktPair` draft type extensions:
- drop requirements for `src_type`, and offer the optional `.dst_type`
  field as either a `str` or (new `typing.Literal`) `AssetTypeName`.
- define an equivalent `.quantize()` as (re)defined in `Symbol` but with
  `quantity_type: str` field which specifies whether to use the price or
  the size precision.
- add a lot more docs, a `.key` property for the "symbol" name, draft
  property for a `.fqme: str`
- allow `.src` and `.dst` to be of type `str | Asset`

Add a new `Asset` to capture "things which can be used in markets and/or
transactions" XD
- defines a `.name`, `.atype: AssetTypeName` a financial category tag, `tx_tick:
  Decimal` the precision limit for transactions and of course
  a `.quantime()` method for doing accounting arithmetic on a given tech
  stack.
- define the `atype: AssetTypeName` type as a finite set of `str`s
  expected to be used in various ways for default settings in other
  parts of the data and order control layers..
