Label the market condition before you look at the result
One column I've added to my journal is a market condition label: trending, ranging, or choppy, sometimes with a note on volatility. The important part is when I fill it in. I do it based on the chart before the entry, not after the trade is closed.
If you label the condition afterwards, the result tends to influence the label. A losing trade in a trend becomes a choppy market. A winning fade becomes a range. The labels then end up confirming what you already think, and they stop being useful for analysis.
Labelling before the result, ideally at the time of entry or from a screenshot taken at entry, gives you a cleaner view. After a few weeks you can look at your results by condition and see which setups work in which conditions. You might find that a setup you thought was good in all conditions really only works in trending markets.
To make it consistent, define what each label means. For example, trending could mean the last few swing highs and lows on the higher timeframe are moving in one direction. Ranging could mean price is between clear levels. Choppy could mean neither. It doesn't need to be perfect, just applied the same way.
What labels do others use, and when do you fill them in?

Re: Label the market condition before you look at the result
Something that helps with consistency is using a simple objective measure alongside the label, like the higher timeframe ATR compared to its recent average, or whether price is above or below a moving average with a positive slope. You can still keep your judgement label, but the objective measure gives a cross check. If your labels and the measure disagree often, either the definition is vague or the measure isn't capturing what you mean. Either way, you learn something about how you read the market. Even a rough one keeps your labels honest on the days you're tempted to see a trend everywhere.

I'd also suggest a short note of what you expected the market to do next, recorded at the same time as the label. Later you can compare it with what happened. It shows whether your read of the market is generally right, separate from whether your entries and exits are well placed. Some traders find their read is decent but execution is weak, and others the opposite. Knowing which one needs work focuses where you spend your practice time. It also shows whether you tend to call trends too early, which is common.
