Allows for tracking paper engine orders despite the ems not necessarily
being opened by the current order mode instance (UI) in "paper"
execution mode; useful for tracking bots/strats running against the same
EMS daemon.
Like you'd think:
- `load_ledger()` -> ._ledger
- `load_accounrt()` -> ._pos
Also fixup the old `load_pps_from_ledger()` and expose it from a new
`.accounting.cli.disect` cli cmd for trying to figure out why pp calcs
are totally mucked on stupid ib..
Should be the final production backend to switch this over B)
Also tidy up the `update_and_audit_msgs()` validator to log vs. raise
when `validate: bool` is set; turn it off by default to avoid raises
until we figure out wtf is up with ib ledger processing or wtv..
We might as well start standardizing on `brokerd` init such that it can
be used more generally in client code (such as the `.accounting.cli`
stuff).
Deats of `broker_init()` impl:
- loads appropriate py pkg module,
- reads any declared `__enable_modules__: listr[str]` which will be
passed to `tractor.ActorNursery.start_actor(enabled_modules=<this>)`
- loads the `.brokers._daemon._setup_persistent_brokerd
As expected the `accounting.cli` tools can now import directly from this
new location and use the common daemon fixture definition.
After #520 we've moved to better supporting explicit venues for cex
backends which is important where a provider offers both spot and
derivatives markets (kraken, binance, kucoin) and we need to distinguish
which is being traded given a common asset pair (eg. BTC/USDT). So, make
this work for `kraken`'s brokerd such that requests and pre-existing
live order are (un)packed to/from EMS messaging form.
Since crypto backends now also may expand an FQME like `xbteur.kraken`
-> `xbteur.spot.kraken` (by filling in the venue token), we need to use
this identifier when looking up per-market order dialogs or submitting
new requests. The simple fix is to simply look up that expanded from
from the `Feed.flumes` table which is always keyed by the `MktPair.fqme:
str` - the expanded form.
Drop the older `dict[str, ChainMap]` prototype we had since the new
`OrderDialogs` built-out while adding `binance` order support is more
refined and general. Also, handle new and now expect `.spot` venue token
in FQMEs since kraken too has futes markets that we'll likely want to
support eventually.
Use dynamic lookups instead by mapping to the correct http session and
endpoints path using the venue routing/mode key. This let's us simplify
from 3 methods down to a single `Client._api()` which either can be
passed the `venue: str` explicitly by the caller (as is needed in the
`._cache_pairs()` case) or falls back to the client's current
`.mkt_mode: str` setting B)
Deatz:
- add couple more tables to suffice all authed-endpoint use cases:
- `.venue2configkey: dict[str, str]` which maps the venue key to the
`brokers.toml` subsection which should be used for auth creds and
testnet config.
- `.confkey2venuekeys: dict[str, list[str]]` which maps each config
subsection key to the list of venue name keys for doing config to
venues lookup.
- always build out testnet sessions for spot and futes venues (though if
not set the sessions obviously won't ever be used).
- add and use new `config.ConfigurationError` custom exceptions when api
creds are missing.
- rename `action: str` to `method: str` in `._api()` since it's the
proper ReST term and switch what was "method" to be `endpoint: str`.
- mask out `.get_positions()` since we can get that from a user stream
wss request (and are doing that).
- (in theory) import and use spot testnet url as necessary.
Do parsing of the `'symbol'` and check for an `_<expiry>` suffix, in
which case we re-format in capitalized FQME style, do the
`Client._pairs[str, Pair]` lookup and then send the `Pair.bs_fqme` in
the `Order.fqme: str` field.
It's finally a decent little design / interface and definitely can be
used in other backends like `kraken` which rolled something lower level
but more or less the same without a wrapper class.
As you'd expect query and sync the EMS with existing live orders
reported by the market venue by packing them in `Status` msgs and
sending over the order dialog stream before starting the handler tasks.
XXX CAVEAT:
- there appears to be no way (at least on the usdtm market/venue) to
distinguish between different contracts such as perps vs. the
quarterlies?
- for now we just assume that the perp is being used since
there's no indicator otherwise in the 'symbol' field?
- we should maybe open an issue with the futures-connector project to
see how they'd recommend solving this discrepancy?
Only a couple tweaks to make this work according to the docs:
https://binance-docs.github.io/apidocs/futures/en/#modify-order-trade
- use a PUT request.
- provide the original user id in a `'origClientOrderId'` msg field.
- don't expect the same oid in the PUT response.
Other broker-mode related details:
- don't call `OrderDialogs.add_msg()` until after the existing check
since we want to check against the *last* msgs contents not the new
request.
- ensure we pass the `modify=True` flag in the edit case.
There was one trick which was that it seems that binance will often send
the account/position update event over the user stream *before* the
actual clearing (aka FILLED) order update event, so make sure we put an
entry in the `dialogs: OrderDialogs` as soon as an order request comes
in such that even if the account update arrives first the
`BrokerdPosition` msg can be relayed without delay / order event order
considerations.
Was using the wrong key before from our old code (not sure how that
slipped back in.. prolly doing too many git stashes XD), so fix that to
properly match against order update events with 'ORDER_TRADE_UPDATE'.
Also, don't match on the types we want to *cast to*, that's not how
match syntax works (facepalm), so we have to typecast prior to EMS msg
creation / downstream logic.
Further,
- try not bothering with binance's own internal `'orderId'` field
tracking since they seem to support just using your own user version
for all ctl endpoints? (thus we only need to track the EMS `.oid`s B)
- log all event update msgs for now.
- pop order dialogs on 'closed' statuses.
- wrap cancel requests in an error handler block since it seems the EMS
is double sending requests from the client?
For crypto derivatives (at least futes), yes they are margined, but
generally not around a single unit of vlm (like equities or commodities
futes) so don't pre-set the order mode allocator to use a #unit limit,
$limit is fine.
Since the request handler task will work concurrently across venues
(spot, futes, margin) we need to be sure that we look up the correct
venue to update the order dialog and this is naturally determined by the
FQME-style symbol in the `BrokerdOrder` msg; the best way to map that
symbol-key to the correct venue/`Pair` is by using said `._pairs:
ChainMap`.
Further, handle limit order errors by catching and relaying back an
error response to the EMS. Fix the "account name" to be `binance.usdtm`
so that we can eventually and explicitly support all venues by name.
Untested fully but has ostensibly working position and balance loading
(by delegating entirely to binance's internals for that) and an MVP ems
order request handler; still need to fill out the order status update
task implementation..
Notes:
- uses user data stream for all per account balance and position tracking.
- no support yet for `piker.accounting` position tracking.
- no support yet for full order / position real-time update via user
stream.
Since we need them for accounting and since we can get them directly
from the usdtm futes `exchangeInfo` ep, just preload all asset info that
we can during initial `Pair` caching. Cache the asset infos inside a new per venue
`Client._venues2assets: dict[str, dict[str, Asset | None]]` and mostly
be pedantic with the spot asset list for now since futes seems much
smaller and doesn't include transaction precision info.
Further:
- load a testnet http session if `binance.use_testnet.futes = true`.
- add testnet support for all non-data endpoints.
- hardcode user stream methods to work for usdtm futes for the moment.
- add logging around order request calls.
