Another update on TradeHawk. They've got a functional 'Strategies' screen now. You are able to select filled orders and add them to a custom 'strategy'. This strategy will track the performance of a series of trades over time to allow you to easily gather P/L without almost no effort or external spreadsheets/input. Free trial for 30 days, so I'd highly recommend checking it out. Dont' have time to gather screenshots for you, but happy to help if have questions on how it works.
