Market Structure Break (MSB)
M
Definition
An informal chart label for price moving beyond a user-defined prior swing high or low. It is not a standardised measure, proof of institutional order flow, or confirmation of a trend reversal.

Key Takeaways
1
MSB is an informal chart label; its swing, timeframe, and close or wick rule must be declared to be reproducible.
2
A move beyond a prior swing does not prove institutional activity, liquidity conditions, direction, or a future return.
3
A close beyond a selected level is an analyst rule, not universal confirmation of a trend change.
4
Test any full decision out of sample with realistic costs and loss scenarios; do not use an MSB alone as an entry signal.
Practical Example
A researcher defines a four-hour swing as a local high or low with two completed bars on either side and records a close above that high as an MSB. They keep the original price feed and timestamps, test the rule in separate market periods with costs, and report both failed and successful breaks. They do not infer the identities or intent of traders or place an order from the label alone.
