The three sessions that run the clock
Sessions & Killzones
A 24-hour relay
Forex and futures trade nearly 24 hours, split into three overlapping sessions (Asia, London, New York). Each one has its own personality, and knowing which is currently open tells you what kind of price action to expect.
Everything anchors to New York time
Session times are anchored to New York time in this course, since that's the reference point most institutional desks use, even for pairs that don't involve the US dollar.
Session extremes carry forward
Each session tends to build its own high and low. Those levels don't disappear when the session ends, they often become the liquidity the next session reaches for.
