Most structure reading fails in the same place: the chart makes a new high, the trader keeps calling it an uptrend, and the last low has already been lost. A trend has two legs. Losing one of them is not a detail, it is the phase change — and it deserves its own name rather than being filed under noise.
1. Two conditions, not one
A clean uptrend requires a higher high and a higher low. A clean downtrend requires a lower high and a lower low. If you check only the highs, a market that keeps reaching but keeps giving back more still reads as bullish, and it is not. Requiring both sides to agree is what turns a subjective read into a rule that can be checked on any chart, in any market.
2. The transition has a shape
When only one side turns, the picture is recognisable: highs that stop advancing while lows still hold, or lows that keep sinking while a single high still stands out. That mixed state is where trends go to end. It is also where most false breaks happen, because the two sides of the market are giving contradictory evidence and each one attracts its own crowd. distils that bias into a single higher-timeframe read.
3. The first contradiction is the earliest warning
The first lower high after a run of higher highs, and the first higher low after a run of lower lows, are the earliest cracks a structure gives. They arrive well before the overall phase flips, which is exactly what makes them useful: they are the point at which risk is worth trimming, not the point at which the reversal is already priced.
4. What to do with a market in transition
Transition is a reason to be smaller, not a reason to guess the direction early. Waiting for the sequence to resolve to one side costs a few bars of entry and removes most of the trades that look obvious and go nowhere. And a transition on one timeframe inside a clean trend on a higher one is a very different situation from a transition that shows up on both — which is why structure is read in confluence, never on a single chart.
