Minute markers refer to specific time intervals used in high-frequency trading and short-term market analysis to identify patterns, execution timing, and market microstructure behavior. These markers help traders identify optimal execution windows, understand intraday volatility patterns, and develop algorithmic trading strategies based on precise timing.

Minute-level analysis reveals market patterns invisible in longer timeframes, including opening and closing auction effects, news reaction timing, and liquidity variations throughout trading sessions. Professional traders use minute markers to optimize execution algorithms and identify consistent patterns in market behavior. Understanding these patterns helps improve execution quality and timing.

Real-world example: A high-frequency trader identifies that EUR/USD liquidity consistently improves at 15-minute intervals following London market open, using these minute markers to optimize large order execution timing and minimize market impact.
