I have noticed that I am missing some opportunities while starting trading at 9:30 AM EST. If I start at 3:00 AM EST, i might have won more trade. so, london traders trade US stocks / precious metals / forex actively and is it good to start early?
I am novice btw 
so if you think my question is like that, I understand.
yes, London session has a lot of volatility, as well as US session. I prefer US session right now because it’s easier for me to monitor my trades during that time.
thanks. Actually, I meant indices not stocks but I think your answer is still valid
lol yea i dont trade stocks currently, but US session most definitely
the US Indices are traded 24 hours a day(excluding Saturday and Sunday)…What you see in the London hours(before US hours) of trading are mostly UK institutions adjusting their US positions.
However, as majority of orders hit the exchange at 09:30 EST. 9:30-10:00 EST will always have the highest volatility as orders from around the world are flooding in and a price is trying to settle.
I was part of a team that built an algo for a bank that wanted to trade the first 5 minutes before open…I can walk you through the process and some of the rules they used
If you want high vol I would recommend US100 at the open
