当前平台不支持自动安装更新。

Error message

当前平台不支持自动安装更新。

What it means

Raised when recording a sell whose quantity exceeds the position available as of the trade date. _validate_sell_quantity (portfolio_service.py:691) normalizes the (symbol, market, currency) key, replays events up to trade_date via _calculate_available_quantity, and throws PortfolioOversellError (code=portfolio_oversell) when available + EPS < requested. The exception carries symbol, trade_date, requested_quantity and available_quantity attributes.

Solutions

Import trades in chronological order and insert missing buy or split_adjustment events first
Inspect the exception fields (available_quantity, trade_date) to see what the replay thinks you hold
Verify market/currency of the sell match the recorded buys so the (symbol, market, currency) key aligns
If you genuinely short-sell, this service rejects it by design: record only covered sells

Example fix

# before
svc.add_trade(account_id=1, symbol="AAPL", side="sell", quantity=200, trade_date=date(2025,1,10), ...)
# after
# record the missing split first, then the sell
svc.add_corporate_action(account_id=1, symbol="AAPL", action_type="split_adjustment", split_ratio=2.0, effective_date=date(2025,1,5))
svc.add_trade(account_id=1, symbol="AAPL", side="sell", quantity=200, trade_date=date(2025,1,10), ...)

Defensive patterns

Strategy: try-catch

Validate before calling

def available_before_sell(svc, account_id, symbol, market, currency, trade_date):
    # replay the same computation the service does
    return svc._calculate_available_quantity(
        account_id=account_id,
        key=(svc._normalize_symbol_for_position(symbol), svc._normalize_market(market), svc._normalize_currency(currency)),
        as_of_date=trade_date,
    )

Type guard

from src.services.portfolio_service import PortfolioOversellError

def is_oversell(exc: Exception) -> bool:
    return isinstance(exc, PortfolioOversellError)

Try / catch

from src.services.portfolio_service import PortfolioOversellError

try:
    svc.add_trade(account_id=a, side="sell", quantity=q, ...)
except PortfolioOversellError as exc:
    # exc.available_quantity, exc.trade_date, exc.symbol carry the diagnosis
    raise UserInputError(f"only {exc.available_quantity} shares available on {exc.trade_date}") from exc

Prevention

Import buys and splits before the sells they cover, in date order
Record split_adjustment events before later sells
Match market and currency of sells to the recorded buys
Read the exception's available_quantity instead of recomputing the position yourself

When it happens

Trigger: add_trade(side='sell', quantity=200) when replay of buys/splits up to that date yields only 100 shares; selling before the covering buy (trade_date earlier than the buy's date); selling in the wrong market/currency key so the matching position is not found; a prior split_adjustment event missing so available quantity is understated.

Common situations: Importing broker history out of order (sells before their buys); forgetting to record a stock split before later sells; selling HK shares recorded under a different currency key; rounding: fractional-share lots where cumulative float error exceeds EPS; margin/short selling, which this service does not model.
