Obviously and in case everyone doesn't know:
-volumne is heaviest when markets overlap and a better time to trade.
-almost 3/4 or all trading in NY occurs WHILE EU is open/trading.
-at least half of all traders are in US or UK
- market open order: New Zealand, Australia, Asia, Middle East, Frankfurt (EUR),
London, USA ( all of these are effectivly ahead of us) so when the market opens sunday it is NZ first then AU and lastly NY opens the next morning at 800 (or 930)
depending on who you talk to

but officially it is 8AM.
The majority of all trading occurs AGAIN during open markets overlapping,
AND during the first 144 minutes of a market opening.
I am not normally affected too much by this, but this is when the market will move which is the best time to trade and the best time to make a profit and you will notice perhaps these times are when the market moves the most as more traders are trading in more places in the world.
