Provide-API-for-broker-account-data

It would be great if we can get APIs to do basic portfolio checks like:
FindPortfolioOpenPosition(string symbol, int quantity, PositionType)

Then we could use it like this:

CODE:

// Cover trade if theoretical short trade exists and actual short position also exists.
// If theoretical or actual short position don't exist then don't cover
if (FindOpenPosition(PositionType.Short) != null && FindPortfolioOpenPosition(mySymbol, myQuantity, PositionType.Short) != null)
{
         PlaceTrade(bars, TransactionType.Cover, OrderType.Limit, ...);
}

In backtest mode, the portfolio APIs will have to behave similar to having a theoretical position to allow strategy to execute the same way as if portfolio APIs were not used.
