Tyler Goodlet 45bef0cea9 Add non-state-incremented calculation methods
Since we're going to need them anyway for desired features, add
2 new `Position` methods:
- `.calc_be_price()` which computes the breakeven cost basis price
  from the entries in the clears table.
- `.calc_size()` which just sums the clear sizes.

Add a `cost_scalar: float` control to the `.update_from_trans()` method
to allow manual adjustment of the cost weighting for the case where
a "non-symmetrical" model is wanted.

Go back to always trying to write the backing ledger files on exit, even
when there's an error (obvs without the `return` in the `finally:` block
f$#% up).

Tyler Goodlet 5684120c11 Wow, drop idiotic `return` inside `finally:`
Can't believe i missed this but any `return` inside a `finally` will
suppress the error from the `try:` part... XD

Thought i was losing my mind when the ledger was mutated and then
an error just after wasn't getting raised.. lul.

Never again...

Tyler Goodlet 6747831677 Don't pop zero pps from table in `.dump_active()`
In order to avoid double transaction adds/updates and too-early-discard
of zero sized pps (like when trades are loaded from a backend broker but
were already added to a ledger or `pps.toml` prior) we now **don't** pop
such `Position` entries from the `.pps` table in order to keep each
position's clears table always in place. This avoids the edge case where
an entry was removed too early (due to zero size) but then duplicate
trade entries that were in that entrie's clears show up from the backend
and are entered into a new entry resulting in an incorrect size in a new
entry..We still only push non-net-zero entries to the `pps.toml`.

More fixes:
- return the updated set of `Positions` from `.lifo_update()`.
- return the full table set from `update_pps()`.
- use `PpTable.update_from_trans()` more throughout.
- always write the `pps.toml` on `open_pps()` exit.
- only return table from `load_pps_from_toml()`.

Tyler Goodlet 9326379b04 Add a `PpTable` type, give it the update methods
In an effort to begin allowing backends to have more granular control
over position updates, particular in the case where they need to be
reloaded from a trades ledger, this adds a new table API which can
be loaded using `open_pps()`.

- offer an `.update_trans()` method which takes in a `dict` of
  `Transactions` and updates the current table of `Positions` from it.
- add a `.dump_active()` which renders the active pp entries dict in
  a format ready for toml serialization and all closed positions since
  the last update (we might want to not drop these?)

All other module-function apis currently in use should remain working as
before for the moment.

Fsp shm caching
2022-07-19 09:55:27 -04:00
Tyler Goodlet 0ef5da0881 Unbreak regular searches and stock lookups..
Change `.find_contract()` -> `.find_contracts()` to allow multi-search
for so called "ambiguous" contracts (like for `Future`s) such that the
method now returns a `list` of tracts and populates the contract cache
with all specific tracts retrieved. Let it take in an (unvalidated)
contract that will be fqsn-style-tokenized such that it can be called
from `.search_symbols()` (though we're not quite yet XD).

More stuff,

- add `Client.parse_patt2fqsn()` which is an fqsn to token unpacker
  built from the original logic in the old `.find_contract()`.
- handle fiat/forex pairs with the `'CASH'` sectype.
- add a flag to allow unqualified contracts to fail with a warning msg.
- populate the client's contract cache with all expiries of
  an ambiguous derivative.
- allow `.con_deats()` to warn msg instead of raise on def-not-found.
- add commented `assert 0` which was triggering a debugger deadlock in
  `tractor` which we still haven't been able to create a unit test for.

Tyler Goodlet 4bcb791161 Finally solve the last-price-is-`nan` issue..
Not sure why I put this off for so long but the check is in now such
that if the market isn't open or no rt quote comes in from the first
query, we just pull from the last shm history 'close' value.
Includes another fix to avoid raising when a double remove on the client
side stream from the registry sometimes happens.
