// CRITICAL PRICE/DECIMAL TYPE FIXES - Agent 16

// 1. Add missing From<Price> for Decimal trait implementation
impl From<Price> for Decimal {
    fn from(price: Price) -> Self {
        price.to_decimal().unwrap_or_else(|_| {
            eprintln!("Failed to convert Price to Decimal, using ZERO as fallback");
            Decimal::ZERO
        })
    }
}

// 2. Add value() method extension for Decimal compatibility  
pub trait DecimalExtensions {
    fn value(&self) -> Self;
}

impl DecimalExtensions for Decimal {
    fn value(&self) -> Self {
        *self
    }
}

// 3. Position struct field corrections
// Fix: Position.avg_cost should be Position.avg_price  
// Fix: Volume::new() returns Result, need to handle properly
