use rust_decimal::Decimal;
use chrono::NaiveDate;
use std::str::FromStr;

let ticker = Ticker::try_from("AAPL").unwrap();

let ticker_copy = ticker;

assert_eq!(ticker, ticker_copy);
assert_eq!(ticker, "AAPL");

let contract = OptionContract::from_osi("SPXW231127C03850000").unwrap();

let contract_copy = contract;
assert_eq!(contract, contract_copy);

assert_eq!(contract.ticker(), "SPXW");
assert_eq!(contract.option_type(), OptionType::Call);
assert_eq!(contract.expiry(), NaiveDate::from_str("2023-11-27").unwrap());
assert_eq!(contract.strike(), Decimal::from(3850));

let contract = OptionContract::from_dx_feed(".SPXW231127C3850").unwrap();
