(Asia, finance) A style of financial chart used to describe price movements of a security, derivative, or currency.

For parents

"k-line" means: A style of financial chart used to describe price movements of a security, derivative, or currency.. This is technical or formal vocabulary, more likely to appear in school work, news or a particular profession than in peer chat. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your child uses the term, it is usually a sign of curiosity about a subject area. A short follow-up question about where they came across it is usually all that is needed.

For ESL learners

"k-line" means: A style of financial chart used to describe price movements of a security, derivative, or currency.. Register: formal or technical English, standard in its specialist domain (law, medicine, science, finance, etc.). Gloss the term with a plain synonym when writing for a general audience. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.
