worst time of day to trade?

I noticed in my demo that many trades stay pending for a very long time. What would the hours of the day be that liquidity would be really low?

Right now it is 10:30pm Pacific and can't fill some orders.

1. Absolute Worst: Between the end of NY session and beginning of Tokyo.
2. 2nd Worst: Asian session; although it can have some very large moves. Really depends on fundamental triggers / volatility.

Just noticed you are Pacific Time; same as me. Who's your broker and what instrument are you having problems getting filled?

Did not want to mention their name and do them any discredit as I see how damaging things like that can do to honest brokers so I just wanted to know the times that are not good for trading. It is a web demo, so going live may be very different and better. Thanks for letting me know what times are bad and I'll just stay away during then and see if things get better.

really doesn't matter what time of day you trade if you're trading longer timeframes.
