Why different price after hours ?

Hi ! Yahoo finance shows that after hours my stock is up 1.5%, I have an open IB platform TWS and after 4pm IB showed the same bid and ask price all the time. Does anybody know any explanation to this ?

 

Old chinese saying


Man with two clocks never know what time it is.

 

unilfy,

Everything in the market has two viewpoints. You need to choose one and go with it.

 

I am sorry if you are so smart then probably you could guys drop a line and explain why...

I am not a professonal.. so it is normal that I dont know this.

I dont see anything stupid about my question.

Let me ask it a bit differently.

I bought stock XYZ

After hours: TWS showes bid: 32.30 ask: 32.38 And it doesnt change.
I went to check news on Yahoo for this XYZ stock and saw after hours the stock jumped 1.5%

Anybosy can explain this ? I would appreciate it. Thanks
