I have managed to finally implement an automated trading system that works perfectly with just two programs open - one excel sheet and TWS by IB. It's very light, it works fine, sending an order in less than a second, which is enough for me. And it even makes money. I won't tell you exactly how the system works, and I won't sell it either, but if anyone has any questions, objections, advice, ideas, please let me know. It took me months and months, so I would like to talk a little bit about what I did, and how it's possible, because at the start I had no idea on whether it was even possible. I am very satisfied now. If it wasn't for a friend of mine, who's very good at writing excel visual basic macros, I would have never made it.
