What is a trading signal?
In one line: A trading signal is a cue, from a rule, an indicator or the chart, that conditions for a trade you've planned are now in place.
A simple example
Your written rule: "In an uptrend on the 4-hour chart, a signal is a 1-hour candle body closing back above the last place price turned down."
Price is in an uptrend. The 1-hour candle closes at 101.40, above the level at 101.00. That's your signal. Not a guaranteed win, just the cue to run your checklist.
Then the rest of the plan takes over: stop below the last low at 100.20, risk 1%, size from the math. Target at 2 times the risk. If it fails, you lose about 1R. A math example, not a promise.
Where signals come from
- Price: a Breakout with a body close, a Retest that holds, a turning point.
- Indicators: a moving average cross, RSI leaving a zone.
- Other people: alert services and chat groups.
Signals from your own tested rules are the only ones you can judge, because you know exactly what they are.
Why it matters
A clear signal turns "I think it'll go up" into a yes-or-no question. That makes it testable. You can replay 100 past charts and count how your signal behaved. See how to backtest a trading strategy.
Signals work best with context. A signal at a key level, with the bigger chart, is stronger than one in the middle of nowhere. That's Confluence.
A common mistake
Paying for signals you can't check. A stranger's "BUY NOW" gives you no stop logic, no record you can verify, and no way to learn. Many signal sellers show only wins. See the myth that copying signals is a shortcut.
A signal is the start of a checklist, not the end of one. Run your pre-trade checklist every time.

Questions
What is a buy signal?
A cue from your rules that conditions for a buy trade are in place. It's a reason to check the plan, not a promise of a gain.
Are trading signals reliable?
No signal works every time. Its value depends on how it's tested, where it appears and how the risk is managed.
What is a false signal?
A signal that triggers but the move doesn't follow, like a breakout that turns into a Fakeout. That's why the stop comes first.
