Trading Signals Explained: Entry, Stop Loss, and Take Profit

A trading signal is a specific, actionable trade idea -- typically an instrument, a direction (buy or sell), an entry price or zone, a stop-loss level, and one or more take-profit levels. It's the output of someone else's (or some system's) analysis, packaged so it can be acted on quickly, rather than the full analysis itself.

The entry is the price or zone at which the signal suggests opening the position -- sometimes a single price for an immediate market order, sometimes a range for a pending limit order if the signal is anticipating a pullback first. The stop-loss is the price at which the idea is considered wrong and the trade should be closed to cap the loss -- this is non-negotiable risk management, not optional context. Take-profit levels mark where some or all of the position is closed to lock in gains, and signals often include more than one target so part of a position can be closed early while the rest runs further.

A signal on its own says nothing about position size -- that's still the trader's decision, based on their own account size and the risk-per-trade rules from Module 8. Two traders following the identical signal should very often use different position sizes, because their accounts and risk tolerance are different; blindly copying a signal's implied size (if it even states one) skips the most important risk-management step.

Signals can come from a human analyst, an automated system, or a copy-trading master account, and quality varies enormously between sources. Treating a signal as a starting point to evaluate -- does the stop-loss make sense, is the risk-reward reasonable, does it fit the trader's own account risk rules -- is safer than treating it as an instruction to execute without question.
