I looked through their user's guide or class description and it seems to be more complicated than ABs auto trading interface, AT. The AB example is very crude and only discusses how to connect. That is just the tip of the iceberg. Managing your orders may be a lot more difficult and you will have to write the code just as you would with AT. I write AT code and writing to the TWSLink interface does not seem a trivial task just as it is not a trivial task to write to the AB AT interface.
The only foible I know of with AB AT is when IB changes their interface in a way that causes trouble. They did that recently and Tomasz fixed AT to accommodate that. I will bet TWSLink had the same problem because IB changed the way TWS returned order status just out of the blue with no warning at all when I was trading after normal hours. Blew my program up. It simply quit trading and I had orders on. That wasn't ATs fault, it was TWS. I had to go back a TWS version and wait for a fix to AT. One plus on the AB AT interface is that you manage it and nothing is hidden from you. If your system does not perform correctly you can dump all sorts of data, add trace and so on. I put status in the interpretation window, log all my trades to a file with the reasons my system acted ( buy/sell conditions ), and trace all the steps in my program so I can find out why the system did not work as expected. And believe me it will surprise you!!! What you see on a static chart after the fact is not what happens while trading with live data. TWSLink seems to provide that ability but you will have to program your AB indicators to handle that. If your system is complex, not a simple cross system or MA direction system you will need all sorts of extra data to let you know what is going in with your system. Mine is based on a decision tree with many inputs and if it doesn't trade when I think it should I want to know why. The data I collect tells me why. I collect it and dump in a file with time stamps so I can compare TWS log with mine. That is possible whether using TWSLink or AT since your formula is controlling the orders with either APO. I would like to hear from the TWSLink user(s) and see what they think, especially if they moved from AT to TWSLink. TWSLink and AB AT are both free. Looking at both interfaces you still have to write the code between your formula and their interface yourself, just as you do with AT. The effort may be the same. I have foibles in my code that cause me grief but I think that would have been the case had I written to TWSLink too. Managing your orders from an indicator isn't easy. Since I wrote the trading code myself I will stick with AT unless there is compelling reason to switch. One nice thing about AT is when we have a problem Tomasz gets right on it.
