"Strategy" in trading just means a consistent, defined approach to deciding when to enter and exit positions, rather than reacting moment to moment. There's no single correct strategy — different approaches suit different market conditions, timeframes, and temperaments. This is a plain overview of a few broad categories you'll come across, not a recommendation to use any of them.

Trend-following

Trend-following approaches try to identify a market that's moving persistently in one direction and join that movement, on the reasoning that a trend already in motion is more likely to continue than reverse in the near term. Moving averages (covered in a separate article) are a commonly cited tool for gauging trend direction. Trend-following approaches tend to struggle in choppy, directionless markets, where price moves back and forth without establishing a clear trend.

Range trading

Range trading assumes a market moving between a fairly consistent high and low (a "range") will likely continue doing so until something changes, and looks to act near the boundaries of that range. This approach tends to struggle when a market breaks out of its established range, since a strategy built around bouncing between boundaries offers little guidance once those boundaries no longer hold.

Breakout trading

Breakout approaches try to catch the start of a new move, entering when price pushes beyond a defined level of prior resistance or support, on the idea that such a break can signal the start of a stronger move. This runs the specific risk of "false breakouts," where price pushes past a level only to reverse shortly after.

No strategy removes the need for risk management

It's worth being direct about something education content in this space doesn't always say clearly: every one of these approaches has periods where it performs well and periods where it doesn't, and none of them replace the position-sizing and stop-loss discipline covered in the risk management article. A strategy describes when you act; risk management describes how much that action can cost you if it's wrong. Both matter, and neither is optional.
