In plain English
What Trading signal means
A trading signal tells a trader that a condition has been met and a trade may be considered. Signals can come from technical rules, price patterns, news, quantitative models, or a human analyst. They are not the trade itself; they are an input that may or may not be acted on. Signal providers may also specify entry, exit, and risk levels.
Why it matters
Signals are the bridge between analysis and execution. Understanding where a signal comes from, how it is generated, and what assumptions it uses helps you judge whether it is repeatable, timely, and suitable for the market being traded. That matters because a weak or misread signal can create false confidence and poor execution decisions.
Example
A simple moving-average system might issue a buy signal when the 20-day average crosses above the 50-day average. The signal is the crossover condition; the actual trade happens only if the trader enters an order. In this simplified example, the signal does not guarantee profit and ignores costs and slippage.
Quick answers
Common questions
Is a trading signal a recommendation?+
Often yes, but not always. Some signals are explicit buy or sell recommendations, while others are rule-based triggers that simply mark a possible setup.
Can a human produce a trading signal?+
Yes. A trader, analyst, or mentor can generate a signal manually, not just an algorithm or indicator.
