๐ Understanding Trading Sessions
Why Sessions Matter
Different trading sessions have dramatically different characteristics:
โข Volume: Sessions determine who's in the market (retail vs institutional)
โข Volatility: Major sessions bring major moves
โข Liquidity: Better fills and tighter spreads during active sessions
โข Trends: Real trends start during London/NY, not Asian
โข Reversals: Often happen at session opens/closes
Professional traders time their entries based on sessions - now you can too.
