* feature: add webull brokerage core integration
- add BrokerageName.Webull enum value
- add WebullBrokerageModel supporting Equity, Option, IndexOption
- add WebullFeeModel with zero commission for equity/option, tiered index option fees (SPX, SPXW, VIX/VIXW, XSP, DJX, NDX/NDXP), 0.6% crypto fee
- register Webull in IBrokerageModel factory switch and GetBrokerageName
- add webull config keys and live-webull environment to Launcher/config.json
- add WebullBrokerageModelTests (CanSubmitOrder, GetFeeModel)
- add WebullFeeModelTests covering all index option tiers and crypto
* refactor: split webull supported order types per security type
- replace flat _supportSecurityTypes/_supportOrderTypes with _supportedOrderTypesBySecurityType dictionary
- options and index options: Limit, StopMarket, StopLimit only
- equity, future, crypto: Market, Limit, StopMarket, StopLimit, TrailingStop
- add WebullOrderProperties with OutsideRegularTradingHours flag
- add messages for unsupported order type validation
* fix: add market order type to option and index option supported orders
* chore: add webull crypto symbols to symbol-properties-database
* test: consolidate webull fee model and brokerage model tests
- merge per-tier and per-symbol [Test] methods into [TestCase]/[TestCaseSource] parameterized tests in WebullFeeModelTests
- replace CreateIndexOptionSecurity/CreateOptionSecurity/CreateCryptoSecurity with single CreateSecurity(SecurityType, decimal, string) helper
- rename test methods to PascalCase (drop underscores) in WebullBrokerageModelTests
- remove section-separator comments from WebullBrokerageModelTests
- update Launcher/config.json for local Webull UAT environment
* remove: restriction GTC for Option and Buy side only
* refactor: limit webull to equity and options
- remove crypto and future support from order types and tests
- remove crypto fee logic and crypto symbol-properties rows
- reject market orders with outsideRth on equity
- log info when market order uses non-day tif
* Throw clear error when AddData is called with a non-class first argument from Python
Calls like self.add_data("VIX", Resolution.DAILY) routed through CreateType, which
silently built a dynamic assembly named after the string and returned a fake type
whose activator factory tried to invoke the str like a function. The downstream
'str' object is not callable PythonException surfaced confusingly (and could
manifest as an apparent hang depending on where it was caught), making the actual
mistake hard to diagnose.
Validate the PyObject up front via TryCreateType in the AddData(PyObject, ...)
entry points and throw an ArgumentException pointing the user at AddEquity /
AddForex / etc. when the argument is not a custom data class.
* Improve the error message
Use only two alternative methods as examples, as we don't need an exhaustive list.
* Allow SetAccountCurrency after SetCash without throwing
Previously, calling SetAccountCurrency after SetCash threw an
InvalidOperationException. The portfolio manager now switches the
base account currency in place: the previous Cash entry (and its
balance) is preserved in the CashBook, and a notice is logged. When
the new account currency matches the existing one, an optional
startingCash overrides the previously set amount and the override
is logged.

* Simplify SetAccountCurrency remarks and drop unused message
Tightens the XML remarks to two cases (different currency: keep previous
in its own entry; matching currency: override). Also removes the now
unused CannotChangeAccountCurrencyAfterSettingCash string since the
portfolio no longer throws.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* Simplify in-line comment in SetAccountCurrency
Drops the "Undo that migration" wording (residue from a previous fix
attempt) and just describes what the branch does: keep the previous
balance in its own currency entry while the new account currency starts
at zero.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* Differentiate implicit vs explicit SetCash on account currency switch
SetCash(decimal) is currency-agnostic: the amount is "this many units of
the (eventual) account currency". Switching the account currency now
re-labels the amount onto the new currency instead of preserving the
previous one. SetCash(symbol, ...) for the current account currency keeps
the old behaviour of preserving the balance in its own CashBook entry.
Splits the existing tests by overload and adds a starting-cash variant
for the explicit case.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* Mark base cash explicit on any SetCash(symbol, ...) call
Broaden _baseCashSymbolSetExplicitly so any call to the explicit-currency
overload signals the user is committing to named currencies, not just
calls whose symbol matches the current account currency. SetAccountCurrency
then preserves the previous base-currency balance in its own CashBook
entry whenever the user has touched the explicit overload at all.

because some of the strings were being casted without using
