Using `tractor.trionics.collapse_eg()` as needed to avoid, at the least,
crash-worthy (in debug-mode REPL-ing terms) nested cancellation egs that
exhibit on SIGINT/ctl-c of each "app" (chart & daemon).
Also a bit of renaming of all `trio.Nursery`s to `tn`, the new "task
nursery" shorthand-var-name being used in all our other `tractor`
related projects.
Since we're not quite yet using automatic typed msging from
`tractor`/`msgspec` (i.e. still manually decoding order ctl msgs from
built-in types..`dict`s still not `msgspec.Struct`) this adds the
appropriate typecasting ops to ensure the required precision is attained
prior to processing and/or submission to a brokerd backend service.
For the `.clearing._ems`,
- flip all `trigger_price` previously presumed to be `float` to just
the field-identical `price: Decimal` and ensure we cast to `float`
for any `trigger_price` usage, like before passing to `mk_check()`.
For `.ui.order_mode.OrderMode`,
- add a new `.curr_mkt: MktPair` convenience property to get the
chart-active value.
- ensure we always use the `.curr_mkt.quantize() -> Decimal` before
setting any IPC-msg's `.price` field!
- always cast `float(Order.price)` before use in setting line-levels.
- don't bother setting `Order.symbol` to a (now fully removed) `Symbol`
instance since it's not really required-for-use anywhere; leaving it
a `str` (per the type-annot) is fine for now?
This also officially moves the code base to using `PyQt6` including all
necessary reference changes and enum namespace path moves.
Also includes a small `.ui.order_mode` fix to cancel any
`Order.price <= 0` and a name error fix with logging using `msg`,
which is already used for the input order msg..
Ran into this trading a peenee where a dark got (mistakenly) submitted
at a price of 0 and then that consecutively broke upstream allocator/pp
code due to a divide-by-zero.. So instead always check for a zero-price
(since that should never ever be valid in any market) and instead cancel
any such order in the EMS and return `None` so that upstream callers can
ignore it without crash handling.
This took a teensie bit of reworking in some `.ui` modules
more or less in the following order of functional dependence:
- add a `Ctl-R` kb-binding to trigger a `Viz.reset_graphics()` in
the kb-handler task `handle_viewmode_kb_inputs()`.
- call the new method on all `Viz`s (& for all sample-rates) and
`DisplayState` refs provided in a (new input)
`dss: dict[str, DisplayState]` table, which was originally inite-ed
from the multi-feed display loop (so orig in `.graphics_update_loop()`
but now provided as an input to that func, see below..)
- `._interaction`: allow binding in `async_handler()` kwargs (`via
a `functools.partial`) passed to `ChartView.open_async_input_handler()`
such that arbitrary inputs to our kb+mouse handler funcs can accept
"wtv we desire".
- use ^ to bind in the aforementioned `dss` display-state table to
said handlers!
- define the `dss` table (as mentioned) inside `._display.display_symbol_data()`
and pass it into the update loop funcs as well as the newly augmented
`.open_async_input_handler()` calls,
- drop calling `chart.view.open_async_input_handler()` from the
`.order_mode.open_order_mode()`'s enter block and instead factor it
into the caller to support passing the `dss` table to the kb
handlers.
- comment out the original history update loop handling of forced `Viz`
redraws entirely since we now have a manual method via `Ctl-R`.
- now, just update the `._remote_ctl.dss: dict` with this table since
we want to also provide rc for **all** loaded feeds, not just the
currently shown one/set.
- docs, naming and typing tweaks to `._event.open_handlers()`
Since it's depended on by `.data` stuff as well as pretty much
everything else, makes more sense to expose it as a top level module
(and maybe eventually as a subpkg as we add to it).
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.
Not sure how this lasted so long without complaint (literally since we
added history 1m OHLC it seems; guess it means most backends are pretty
tolerant XD ) but we've been sending 2 cancels per order (dialog) due to
the mirrored lines on each chart: 1s and 1m. This fixes that by
reworking the `OrderMode` methods to be a bit more sane and less
conflated with the graphics (lines) layer.
Deatz:
- add new methods:
- `.oids_from_lines()` line -> oid extraction,
- `.cancel_orders()` which makes the order client cancel requests from
a `oids: list[str]`.
- re-impl `.cancel_all_orders()` and `.cancel_orders_under_cursor()` to
use the above methods thus fixing the original bug B)
Including changing to `LinkedSplits.mkt: MktPair` and adding an explicit
setter method for setting it and being sure that nothing breaks
in the display system init!
For this commit we leave in warning access to `LinkedSplits.symbol` but
will remove in following commit.
Order mode previously was just willy-nilly sending `float` prices
(particularly on order edits) which are generated from the associated
level line. This actually uses the `MktPair.price_tick: Decimal` to
ensure the value is rounded correctly before submission to the ems..
Also adjusts the order mode init to expect a table of tables of startup
position messages, with the inner table being keyed by fqme per msg.
We previously only offered a sync API (which was recently renamed to
`.<meth>_nowait()` style) since initially all order control was from our
`OrderMode` Qt driven UI/UX. This adds the equivalent async methods for
both testing as well as eventual auto-strat driven control B)
Also includes a bunch of renaming:
- `OrderBook` -> `OrderClient`.
- better internal renaming of the client's mem chan vars and add a ref
`._ems_stream: tractor.MsgStream`.
- drop `get_orders()` factory, just always check for the actor-global
instance and always set the ems stream on that client (in case old one
was closed).
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`.
When the client is faster then a `brokerd` at submitting and cancelling
an order we run into the case where we need to specify that the EMS
cancels the order-flow as soon as the brokerd's ack arrives. Previously
we were stashing a `BrokerdCancel` msg as the `Status.req` msg (to be
both tested for as a "already cancelled" and sent immediately on ack arrival to
the broker), but for such
cases we can't use that msg to find the fqsn (since only the client side
msgs have it defined) which is required by the new
`Router.client_broadcast()`.
So, Since `Status.req` is supposed to be a client-side flow msg anyway,
and we need the fqsn for client broadcasting, we change this `.req`
value to the client's submitted `Cancel` msg (thus rectifying the
missing `Router.client_broadcast()` fqsn input issue) and build the
`BrokerdCancel` request from that `Cancel` inline in the relay loop
from the `.req: Cancel` status msg lookup.
Further we allow `Cancel` msgs to define an `.account` and adjust the
order mode loop to expect `Cancel` source requests in cancelled status
updates.
