Trend line

A line drawn on the chart that connects several lows (or highs).

In brief: A line drawn on the chart that connects several lows (or highs).

Meaning in practice

trend/">Trend lines visualize market structure. As long as an uptrend forms higher lows, it is intact – if the trend line is broken, this can be the first warning signal.

Context for investors and traders

For traders, this term is most useful when preparing and executing an order. Its meaning depends on the venue, liquidity, time frame and order type. A single reading is not a reliable buy or sell decision.

How to use this in practice

In practice, the term should be linked to a specific trading plan: entry, exit, position size and costs belong together. In short time frames, spread, slippage and delayed execution can quickly outweigh the theoretical benefit of an observation.

What to keep in mind

Write down which observation confirms or invalidates your assumption before trading. This keeps the term a decision-making tool rather than a retrospective justification for risk already taken.
