Lesson 4: Support and Resistance

📘 Day Trading in 5 Minutes · Lesson 4 of 10

In Lesson 3 you learned how to pick a timeframe so your chart matches the kind of trade you want to take. Now we put levels on that chart. Support and resistance are the two most useful marks a day trader can draw, and once you see them, the chart stops looking random.

What Support and Resistance Are

Support is a price level where buyers have stepped in before. As price falls toward it, demand tends to show up, and the drop slows or reverses. Think of it as a floor that has held the price up at least once.

Resistance is the opposite. It is a price level where sellers have shown up before. As price rises toward it, supply tends to appear, and the climb stalls or turns back down. Think of it as a ceiling that has capped the price at least once.

You do not need any indicator for this. You are just looking at where price stopped and turned in the past, then expecting traders to react at that same spot again.

Why These Levels Form

Levels hold because traders remember them. Say a stock bounced off $50 last week. Buyers who missed that bounce are watching for another chance near $50. Sellers who bought there and want out at breakeven are watching too. When price returns, all of those orders cluster around the same number, and that pressure pushes price the other way.

This is why round numbers and obvious prior highs and lows matter so much. The more people staring at the same level, the more likely it reacts. A level that has been tested two or three times carries more weight than one touched only once.

How to Mark Them

Keep it simple. Pull up your chart and look for the spots where price clearly reversed direction. Draw a horizontal line across the highs that capped a move, and another across the lows that held a drop.

A few rules that keep your lines honest:

• Use the wicks, not just the bodies. The extreme of a candle shows where price was actually rejected.
• Think zones, not exact prices. A level is a small band, maybe a few cents or a few dollars wide, not a razor-thin line.
• Fewer lines is better. Mark the levels that stand out at a glance. If you need to squint to find it, skip it.

Drawing angled lines along a rising or falling series of highs and lows works the same way. Those are trend lines, and they act as moving support and resistance.

Role Reversal

Here is the part that trips up beginners. When price breaks through a level, that level often flips its job. Old resistance becomes new support, and old support becomes new resistance.

Picture a stock stuck under $50 for days. It finally breaks above and runs to $53. When it pulls back, it often drops to around $50 and holds there before going higher. The ceiling became a floor. The traders who were selling at $50 are now happy to buy it, and the breakout buyers defend their entry. This flip is one of the cleanest setups you will find, and you will lean on it later in this course.
