Market Structure Shift
Also called MSS, Change of Character (ChoCh)
Step 1
What it is
A downtrend is a series of lower highs and lower lows. An uptrend is the opposite. A market structure shift, or MSS, is the first time price closes past the most recent swing that was keeping that pattern going. You may also hear it called a change of character, or ChoCh.
It is the first evidence that a trend may be changing. It is not proof. Plenty of shifts fail, and the old trend simply carries on.
Traders use it as a filter. It stops you buying a falling market just because it looks cheap, and makes you wait for price to show a change first.
Step 2
See it on a chart
A downtrend until price closes past its last lower high.

Step 3
The exact rules
What must be true before entry
- A clear trend, with at least two lower highs or two higher lows.
- A close past the most recent swing point. A wick does not count.
- A strong candle or two behind that close.
What volume should show
Where to enter
Where the hard stop goes
Where the target goes
What invalidates the idea
- Price makes a new extreme past the stop level.
- Price closes back beyond the shift level and stays there.
When not to take it
- The shift came from a small wiggle on a very short timeframe.
- The pullback never comes. Missing a trade costs you nothing.
- Major news is due soon, or you would be trading outside your planned hours.
- You have just taken a loss and feel the need to win it back.
Step 4
Your turn: plan the trade
An uptrend has just lost its last higher low on a strong close, and price has pulled back. Mark your plan.
This setup is a short. Look at the candles and the volume. Choose a line below, then tap the chart to place it. You can also drag its label or type a price.

Step 5
The trap: calling the top or bottom
Catching the exact turn feels clever, so people jump in before the shift has happened. That is a prediction, not a plan. Waiting means a worse price and fewer trades, and that is a fair trade for some actual evidence.
