Market Structure

Understanding Break of Structure (BoS) and Market Structure Shift (MSS).

Break of Structure (BoS)

BoS = Price breaks a swing point in the direction of the trend (continuation).

Bullish BoS (Uptrend)

Price breaks above a swing high:

                    ══════════════ BoS (break above HH)
       HH        ╱
      ╱  ╲      ╱

   HL      ╲  ╱

Bearish BoS (Downtrend)

Price breaks below a swing low:

Market Structure Shift (MSS)

MSS = Price breaks a swing point against the trend (reversal signal).

Bullish MSS (Reversal from Downtrend)

Price breaks above a swing high during downtrend:

   LH

                    LL

Bearish MSS (Reversal from Uptrend)

Price breaks below a swing low during uptrend:

                    HH
                   ╱  ╲
                  ╱    ╲

            ╳              ╲
    ════════════════════════════════ MSS (break below HL)

Key Differences

Aspect BoS MSS
Direction With trend Against trend
Meaning Trend continues Potential reversal
Action Look for continuation Look for reversal setup
In RQF First step of setup Confirmation of reversal

In the Indicator

The indicator tracks structure breaks automatically:

  • BoS lines: Thinner, labeled "BoS"
  • MSS lines: Thicker, labeled "MSS"
  • Color: Green for bullish, Red for bearish
