A stop loss is the price at which you exit a trade because it has gone wrong. Where you put it matters enormously: too tight and normal market noise stops you out of good trades; too wide and losses grow larger than they need to be. The best stops are not arbitrary numbers. They sit at the point where the reason for the trade is no longer valid, and position size is then set so that hitting that stop costs a planned amount. See [Position Sizing](https://learn.tradelabsai.com/risk/position-sizing/).

## The guiding principle

> Place the stop where you are wrong, then size the position to make that loss acceptable.

Many beginners do the opposite: they decide how many shares to buy, then place the stop wherever the loss "feels" acceptable. That produces stops at meaningless prices that the market hits routinely.

## Types of stop loss

| Type | How it works | Pros | Cons |
|---|---|---|---|
| Structure stop | Beyond a swing low, support or pattern boundary | Logical; tied to the trade idea | Can be wide |
| Volatility stop | A multiple of ATR from entry | Adapts to each market | Ignores structure |
| Percentage stop | A fixed % from entry | Simple | Ignores structure and volatility |
| Time stop | Exit if the trade has not worked within a set time | Frees capital from dead trades | May exit before a move |
| Trailing stop | Follows price as it moves in your favour | Locks in profit | Can exit on normal pullbacks |
| Indicator stop | Exit on a moving average or Supertrend break | Objective | Lags |

## Structure stops

The most widely used method. For a long trade, place the stop below the most recent swing low or support zone; for a short, above the most recent swing high or resistance. If price breaks that level, the structure that justified the trade has changed. See [Swing Highs and Lows](https://learn.tradelabsai.com/price-action/swing-highs-and-lows/) and [Support and Resistance](https://learn.tradelabsai.com/price-action/support-and-resistance/).

**Example: A structure stop with a buffer**
A stock pulls back to $63.40, bounces and you buy at $65.00. The swing low is $63.40. Many traders' stops sit at $63.39. You place yours at $63.10, a small buffer below the obvious level, roughly a quarter of the stock's $1.20 ATR. Risk per share is $1.90. With $190 of planned risk, you buy 100 shares.

## Volatility stops

Placing the stop 1.5 to 3 times ATR from entry keeps it outside normal noise. Combining structure and volatility, a swing low plus a fraction of ATR, often works best. See [ATR (Average True Range)](https://learn.tradelabsai.com/indicators/atr/) and [Volatility and ATR-Based Sizing](https://learn.tradelabsai.com/risk/volatility-and-atr-based-sizing/).

## Time stops

If a trade was meant to work quickly, such as a breakout, but goes nowhere for several days, many traders exit even if the stop was not hit. The idea is that the expected move has not happened, and the capital and attention are better used elsewhere. See [Time Stops](https://learn.tradelabsai.com/position-management/time-stops/).

## Managing the stop after entry

- **Never move a stop further away** from your entry to avoid a loss.
- **Moving to breakeven** after a set gain reduces risk but can cut winners early if done too soon. See [Moving Your Stop: Breakeven and Trailing Stops](https://learn.tradelabsai.com/position-management/breakeven-stop/).
- **Trailing** the stop behind new swing points or ATR lets profits run. See [Trailing Stop Orders](https://learn.tradelabsai.com/orders/trailing-stop-orders/).

## Mental stops vs real orders

A mental stop is a price you plan to exit at without placing an order. It avoids showing your stop to the market but depends entirely on your discipline and attention. Most traders, especially beginners, are better off with real stop orders. See [Stop Orders](https://learn.tradelabsai.com/orders/stop-orders/).

## Gaps and slippage

Stops are not guarantees. In gaps or fast markets, a stop order fills at the next available price, which can be much worse. Account for this risk through smaller sizes around events and, where available, guaranteed stops. See [Slippage](https://learn.tradelabsai.com/markets/slippage/).

## Common mistakes

- **Stops at round numbers or exactly at obvious levels.**
- **Stops so tight** that normal noise hits them.
- **Moving stops further away** when price approaches them.
- **No stop at all.**

## Frequently asked questions

### Where should I place my stop loss?

At the level where your trade idea is proven wrong, usually beyond a swing point or support or resistance, often with a small volatility buffer.

### Is a percentage stop loss a good idea?

It is simple but ignores market structure and volatility. Structure and ATR based stops are usually more logical.

### Should I use mental stops?

Real stop orders are generally safer, especially for beginners, because mental stops depend on watching the market and acting without hesitation.
