I have decided to use TradeLink to build my day-trade future system instead of building my own system because it gives me the most flexibility while I don't need to rebuild a lot of things that is in TradeLink. Another reason is that it uses real C#. C# should give me a lot of freedom for what I can do and easy to find resource comparing to amibroker/ninjatrader script. TradeLink should have very good performance comparing with all other retail level trading system. If one day I get to very serious level and need to modify TradeLink, it is open source so I can do whatever I need too. Does anyone here get used to TradeLink? Welcome to chat and share!
