Thank you for your input. I think you are correct, IB's servers must be overloaded. The fact that the 4000 port is not working might make it even worse as all the orders must be redirected through 4001 port.
Would you please elaborate your solution? Everything that helps with this issue is very welcome. The truth is that yesterday I was lucky, but I went through a few bad moments when I needed to close my position and that order was pending there for what seemed like an eternity. I actually had to cancel that order and then placed another one that was accepted and filled normally. That´s what I consider is not acceptable. Trading is hard enough, I can´t even consider having pending orders waiting to be filled.
Thank you for your input. I think you are right, currently it is happening when the market is faster. In any case, yesterday and the day before it was a bit fast but not extreme. I have traded more extreme / volatile than these two days and the order execution used to be fast enough. Would you mind to share the name of that different broker you use as alternative, please? Thanks.
Yes, you are correct. Unfortunately, that´s exactly when we need the orders to execute faster too... But what is strange is that it doesn't happen with all orders, just a few. It also happened to have one of these "pending" orders hanging there and enter another order that filled immediately, leaving the first still pending... The problem is we can never know when it will happen again. I can´t trade under these conditions.
Thank you for your input. No, I didn't assume that my order hadn't been submitted from my computer to IB's servers. Exactly the opposite, I was sure that the order was stuck in IB's servers.
Then why did you focus on ports 4000 and 4001 of your computer? That has nothing to do with the interaction between IB's servers and the exchange.

All I can say to this is: if the brakes of your car don't work it makes no sense to investigate the gearbox.
