Tyler Goodlet 201919eef7 Initial option chain UI
Spin it up with `piker optschain`.
Still lots of polishing and features to add but it's a start!

Tyler Goodlet 8647216b75 Tabular kivy UI improvements
`Row`:
- `no_cell`: support a list of keys for which no cells will be created
- allow passing in a `cell_type` at instantiation

`TickerTable`:
- keep track of rendered rows via a private `_rendered` set
- don't create rows inside `append_row()` expect caller to do it
- never render already rendered widgets in `render_rows()`

Miscellaneous:
- generalize `update_quotes()` to not be tied to specific quote fields
  and allow passing in a quote `formatter()` func
- don't bother creating a nursery block until necessary in main
- more commenting

Tyler Goodlet fb47ea2e5a Define option field structure
Add some extra fields to each quote that QT should already be
providing (instead of hiding them in the symbol and request contract
info); namely, the expiry and contact type (i.e. put or call).
Define the base set of fields to be displayed in an option chain
UI and add a quote formatter.

Tyler Goodlet 9f3a316ccf Improve CPU usage using a clock trigger and deque
Copy out `kivy.clock.triggered` from version 1.10.1 since it isn't yet
available in the `trio`/async branch and use it to throttle the callback
rate. Use a `collections.deque` to LIFO iterate widgets each call
using the heuristic that it's more likely the mouse is still within the
currently highlighted (or it's adjacent neighbors) widget as opposed
to some far away widget (the case when the mouse is moved very
drastically across the window).

Tyler Goodlet 5c070b1c43 Faster highlighting via single loop and callback
Thanks yet again to @tshirtman for suggesting this.

Instead of defining a `on_mouse_pos()` on every widget simply
register and track each widget and loop through them all once (or as much
as is necessary) in a single callback. The assumption here is that we
get a performance boost by looping widgets instead of having `kivy` loop
and call back each widget thus avoiding costly python function calls.

Tyler Goodlet c7cf0cde9c Add options streaming
Well that was a doozy; had to rejig pretty much all of it.

The deats:
- Track broker components in a new `DataFeed` namedtuple
- port to new list based batch quotes (not dicts any more)
- lock access to cached broker-client / data-feed instantiation
- respawn tasks that fail due to the network
2018-11-30 08:13:30 -05:00
Tyler Goodlet cd7d8d024d Add option quoter support for streaming
So much changed to get this working for both stocks and options:
- Index contracts by a new `ContractsKey` named tuple
- Move to pushing lists of quotes instead of dicts since option
  subscriptions are often not identified by their "symbol" key and
  this makes it difficult at fan out time to know how a quote should
  be indexed and delivered. Instead add a special `key` entry to each
  quote dict which is the quote's subscription key.

Tyler Goodlet a8a5e836b9 Use static instruction for highlighted row
Instead of all this adding/removing of canvas instructions nonsense
simple add a static "highlighted" rectangle to each row and make its
size very small when there's no mouse over.

Mad props to @tshirtman for showing me the light :D

Tyler Goodlet a7f3008d34 Match the author's general apparel
It's still a bit of a shit show, and I've left a lot of commented tweaks
that need to be further played with, but I think this is a much
better look for what I'm considering to be one of the main "entry point"
apps for `piker`. To get any more serious fine tuning the way I want
I may have to talk to some kivy experts as I'm having some headaches
with button borders, padding, and the header row height..

Some of the new changes include:
- port to the new `brokers.data` module
- much darker theme with a stronger terminal vibe
- last trade price and volume amount flash on each trade
- fixed the symbol search bar to be a static height; before it was
  getting squashed oddly when using stacked windows
- make all the cells transparent (for now) such that I can just use
  a row color (relates to cell padding/spacing - can't seem to ditch it)
- start adding type annotations

Tyler Goodlet b9a9b7a9a3 Add options query and data feed recording commands
Add `contracts` and `optsquote` commands for querying option contracts
info and market quotes respectively. Add a `record` command for
streaming real-time data feed quotes to disk. Port `monitor` to the
new `piker.brokers.data` module. Forward loglevel flags through to
`tractor` for relevant commands.

Tyler Goodlet c23982393d Allow recording data feeds to disk
Add a couple functions for storing and retrieving live json data feed
recordings to disk using a very rudimentary character + newline delimited
format.

Also, split out the pub-sub logic from `stream_quotes()` into a new
func, `fan_out_to_chans()`. Eventually I want to formalize this pattern
into a decorator exposed through `tractor`.

Tyler Goodlet f038fdd42f Add a `contracts()` query
Makes it easy to request all the option contracts for a particular symbol.
Also, let `option_chain()` accept a `date` arg which can be used to only
retrieve quotes for a single expiry date (much faster then getting all
of them).
