We helped drive a bunch of fixes in
https://github.com/barneygale/asyncvnc/pull/4
This pins to our forked but matched `main` branch to get those fixes
until such a time as upstream makes another release.
Quite a simple fix, we just assign the account-specific
`PositionTracker` to the level line's `._on_level_change()` handler
instead of whatever the current `OrderMode.current_pp` is set to.
Further this adds proper pane switching support such that when a user
modifies an order line from an account which is not the currently
selected one, the settings pane is changed to reflect the
account and thus corresponding position info for that account and
instrument B)
We were overwriting the existing loaded orders list in the per client
loop (lul) so move the def above all that.
Comment out the "try-to-cancel-inactive-orders-via-task-after-timeout"
stuff pertaining to https://github.com/erdewit/ib_insync/issues/363 for
now since we don't have a mechanism in place to cancel the re-cancel
task once the order is cancelled - plus who knows if this is even the
best way to do it..
Fills seems to be dual emitted from both the `status` and `fill` events
in `ib_insync` internals and more or less contain the same data nested
inside their `Trade` type. We started handling the 'fill' case to deal
with a race issue in commissions/cost report tracking but we don't
really want to leak that same race to incremental fills vs.
order-"closed" tracking.. So go back to only emitting the fill msgs
on statuses and a "closed" on `.remaining == 0`.
`ib` is super good not being reliable with order event sequence order
and duplication of fill info. This adds some guards to try and avoid
popping the last status status too early if we end up receiving
a `'closed'` before the expected `'fill`' event(s). Further delete the
`status_msg` ref on each iteration to avoid stale reference lookups in
the relay task/loop.
This includes darks, lives and alerts with all connecting clients
being broadcast all existing order-flow dialog states. Obviously
for now darks and alerts only live as long as the `emsd` actor lifetime
(though we will store these in local state eventually) and "live" orders
have lifetimes managed by their respective backend broker.
The details of this change-set is extensive, so here we go..
Messaging schema:
- change the messaging `Status` status-key set to:
`resp: Literal['pending', 'open', 'dark_open', 'triggered',
'closed', 'fill', 'canceled', 'error']`
which better reflects the semantics of order lifetimes and was
partially inspired by the status keys `kraken` provides for their
order-entry API. The prior key set was based on `ib`'s horrible
semantics which sound like they're right out of the 80s..
Also, we reflect this same set in the `BrokerdStatus` msg and likely
we'll just get rid of the separate brokerd-dialog side type
eventually.
- use `Literal` type annots for statuses where applicable and as they
are supported by `msgspec`.
- add additional optional `Status` fields:
-`req: Order` to allow each status msg to optionally ref its
commanding order-request msg allowing at least a request-response
style implicit tracing in all response msgs.
-`src: str` tag string to show the source of the msg.
-`reqid: str | int` such that the ems can relay the `brokerd`
request id both to the client side and have one spot to look
up prior status msgs and
- draft a (unused/commented) `Dialog` type which can be eventually used
at all EMS endpoints to track msg-flow states
EMS engine adjustments/rework:
- use the new status key set throughout and expect `BrokerdStatus` msgs
to use the same new schema as `Status`.
- add a `_DarkBook._active: dict[str, Status]` table which is now used for
all per-leg-dialog associations and order flow state tracking
allowing for the both the brokerd-relay and client-request handler loops
to read/write the same msg-table and provides for delivering
the overall EMS-active-orders state to newly/re-connecting clients
with minimal processing; this table replaces what the `._ems_entries`
table from prior.
- add `Router.client_broadcast()` to send a msg to all currently
connected peers.
- a variety of msg handler block logic tweaks including more `case:`
blocks to be both flatter and improve explicitness:
- for the relay loop move all `Status` msg update and sending to
within each block instead of a fallthrough case plus hard-to-follow
state logic.
- add a specific case for unhandled backend status keys and just log
them.
- pop alerts from `._active` immediately once triggered.
- where possible mutate status msgs fields over instantiating new
ones.
- insert and expect `Order` instances in the dark clearing loop and
adjust `case:` blocks accordingly.
- tag `dark_open` and `triggered` statuses as sourced from the ems.
- drop all the `ChainMap` stuff for now; we're going to make our own
`Dialog` type for this purpose..
Order mode rework:
- always parse the `Status` msg and use match syntax cases with object
patterns, hackily assign the `.req` in many blocks to work around not
yet having proper on-the-wire decoding yet.
- make `.load_unknown_dialog_from_msg()` expect a `Status` with boxed
`.req: Order` as input.
- change `OrderDialog` -> `Dialog` in prep for a general purpose type
of the same name.
`ib` backend order loading support:
- do "closed" status detection inside the msg-relay loop instead
of expecting the ems to do this..
- add an attempt to cancel inactive orders by scheduling cancel
submissions continually (no idea if this works).
- add a status map to go from the 80s keys to our new set.
- deliver `Status` msgs with an embedded `Order` for existing live order
loading and make sure to try an get the source exchange info (instead
of SMART).
Paper engine ported to match:
- use new status keys in `BrokerdStatus` msgs
- use `match:` syntax in request handler loop
Ideally every client that connects to the ems can know its state
(immediately) meaning relay all the order dialogs that are currently
active. This adds full (hacky WIP) support to receive those dialog
(msgs) from the `open_ems()` startup values via the `.started()` msg
from `_emsd_main()`.
Further this adds support to the order mode chart-UI to display existing
(live) orders on the chart during startup. Details include,
- add a `OrderMode.load_unknown_dialog_from_msg()` for processing and
displaying a ``BrokerdStatus`` (for now) msg from the EMS that was not
previously created by the current ems client and registering and
displaying it on the chart.
- break out the ems msg processing into a new
`order_mode.process_trade_msg()` func so that it can be called on the
startup dialog-msg set as well as eventually used a more general low
level auto-strat API (eg. when we get to displaying auto-strat and
group trading automatically on an observing chart UI.
- hackyness around msg-processing for the dialogs delivery since we're
technically delivering `BrokerdStatus` msgs when the client-side
processing technically expects `Status` msgs.. we'll rectify this
soon!
