Tyler Goodlet 0e9b50de4b `_ems`: tolerate and warn on already popped execs In the `translate_and_relay_brokerd_events()` loop task that is, such that we never crash on a `status_msg = book._active.pop(oid)` in the 'closed' status handler whenever a double removal happens. Turns out there were unforeseen races here when a benign backend error would cause an order-mode dialog to be cancelled (incorrectly) and then a UI side `.on_cancel()` would trigger too-early removal from the `book._active` table despite the backend sending an actual 'closed' event (much) later, this would crash on the now missing entry.. So instead we now, - obviously use `book._active.pop(oid, None)` - emit a `log.warning()` (not info lol) on a null-read and with a less "one-line-y" message explaining the double removal and maybe why.		2026-01-07 13:41:07 -05:00

piker.clearing

trade execution-n-control subsys for both live and paper trading as well as algo-trading manual override/interaction across any backend broker and data provider.

avail UIs

order ctl

the piker.clearing subsys is exposed mainly though the piker chart GUI as a "chart trader" style UX and is automatically enabled whenever a chart is opened.

the "manual" order control features are exposed via the piker.ui.order_mode API and can pretty much always be used (at least) in simulated-trading mode, aka "paper"-mode, and the micro-manual is as follows:

order_mode (

edge triggered activation by any of the following keys, mouse-click on y-level to submit at that price ):

f/ ctl-f to stage buy
d/ ctl-d to stage sell
a to stage alert

search_mode (

ctl-l or ctl-space to open, ctl-c or ctl-space to close ) :

begin typing to have symbol search automatically lookup symbols from all loaded backend (broker) providers
arrow keys and mouse click to navigate selection
vi-like ctl-[hjkl] for navigation

position (pp) mgmt

you can also configure your position allocation limits from the sidepane.
