Lesson 8: Stops and Position Sizing

📈 Swing Trading in 5 Minutes · Lesson 8 of 10

In Lesson 7 you learned to time entries with alerts and the daily close instead of chasing the bottom tick. A clean entry is only half the trade. Where you put your stop, and how many shares you buy, decide whether a losing trade is a scratch or a wound you remember for months.

Swing Stops Are Wider Than Day Trade Stops

A day trader might risk 20 cents on a stock and be out by lunch. As a swing trader you are holding for days, sometimes weeks, and a normal stock breathes a lot over that span. It can swing 3 or 4 percent in a quiet week without your thesis being wrong at all.

If you set a tight day trade stop on a multi day position, you will get knocked out by ordinary noise long before your idea has a chance to play out. Swing stops have to sit far enough back to survive the daily wiggles. Wider stops are not sloppy. They match the timeframe you are trading.

Place the Stop Below the Setup

Your stop belongs at the price that proves the trade wrong, not at a round dollar amount that feels comfortable. For most swing setups that price sits just below the structure you entered on.

If you bought a pullback to support, the stop goes a little below that support level. A daily close beneath it tells you the floor cracked. If you bought a breakout, the stop goes below the breakout level or the low of the breakout day. Once price falls back under the level it just cleared, the breakout failed and you have no reason to stay.

Give the stop a small buffer so a one cent undercut does not eject you. Place it a touch below the obvious level, where real damage starts, not exactly on the line every other trader is watching.

Account for Overnight Gaps

This is the risk day traders never face and swing traders cannot ignore. The market closes, news drops after hours, and the stock opens the next morning far below your stop. Your order fills at the open, not at your stop price. That is a gap, and it can hand you a bigger loss than you planned.

You cannot prevent gaps, but you can blunt them. Keep position sizes modest so one bad open cannot dent your account. Be extra careful holding through earnings, which is the most common source of violent gaps. Many swing traders simply close before an earnings report rather than gamble on the overnight move.

Size From a Fixed Account Risk Percent

Here is the habit that keeps swing traders in the game. You decide in advance how much of your account you will risk on any single trade, usually 1 percent, then let that number tell you how many shares to buy. The stop distance changes from trade to trade. The dollar risk stays constant.

Run that math on every trade and one loss can never blow a hole in your account. You can be wrong many times in a row and still have plenty of capital left. If the arithmetic feels tedious, a position size calculator does it in a second so you never skip the step.
