opening of the spy 

What is spy?

If the platform has been disconnected from the internet for a while, it has to update. If you have a poor internet connection/speed it may take a while to update.

 
its really the futures contract of the s&p 500, maybe is the connection but it surprise me that the bid and ask is accurate, i will try with other internet connection thanks¡

How do you know it "lags for minutes", what that means exactly ?

Is it a  demo or real account ?

 
the hour is for example 9:35 and there are only bars till 9:31 in my cellphone appear all the bars but not on the pc, usually happens when there is a lot of volatility. is a demo
