Tyler Goodlet c5b172a7df `binance`: pre-process `Pair` filters at init
Allows us to keep the struct frozen as well avoid complexity in the pure
data type. Also changes `.price/size_tick` to plain ol' properties.

Tyler Goodlet b718b5634e `binance`: use `MktPair` in live feed setup
Turns out `binance` is pretty great with their schema  since they have
more or less the same data schema for their exchange info ep which we
wrap in a `Pair` struct:
https://binance-docs.github.io/apidocs/spot/en/#exchange-information

That makes it super easy to provide the most general case for filling
out a `MktPair` with both `.src/dst: Asset` to maintain maximum
meta-data B)

Deatz:
- adjust `Pair` to have `.size/price_tick: Decimal` by parsing out
  the values from the filters field; TODO: we should probably just rewrite
  the input `.filter` at init time so we can keep the frozen style.
- rename `Client.mkt_info()` (was `.symbol_info` to `.exch_info()`
  better matching the ep name and have it build, cache, and return
  a `dict[str, Pair]`; allows dropping `.cache_symbols()`
- only pass the `mkt_info: MktPair` field in the init msg!

Tyler Goodlet 8f79c37b99 Generalize `MktPair.from_msg()` handling
Accept a msg with any of:
- `.src: Asset` and `.dst: Asset`
- `.src: str` and `.dst: str`
- `.src: Asset` and `.dst: str`

but not the final combo tho XD
Also, fix `.key` to properly cast any `.src: Asset` to string!

Tyler Goodlet aa5f25231a `ib`: never override existing ledger records
If user has loaded from a flex report then we don't want the API records
from the same period to override those; instead just update with any
missing fields from the API schema.

Also, always `str`-ify the contract id (what is set for the `.bs_mktid`
*before* packing into transaction type to ensure when serialized to
`pps.toml` there are no discrepancies at the codec level.. smh

Tyler Goodlet f3049016d6 `ib`: drop use of `_account2clients` in `load_clients_for_trio()`
Instead adjust `load_aio_clients()` to only reload clients detected as
non-loaded or disconnected (2 birds), and avoid use of the global module
table which could result in stale disconnected clients persisting on
multiple `brokerd` client reconnects, resulting in error.

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 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 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.
2023-05-09 14:49:25 -04:00
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..
