Support and Resistance

Support is a price area where falling prices have tended to stop and turn up, because buyers stepped in. Resistance is a price area where rising prices have tended to stop and turn down, because sellers stepped in. They are the most widely used ideas in technical analysis, and for good reason: they mark where the balance between buyers and sellers has shifted before, and where it may shift again.

Why support and resistance work#

Levels work partly because of memory and partly because of orders:

• Memory: traders who bought at $50 and watched price fall to $45 often sell when price returns to $50, just to break even. That creates resistance.
• Regret: traders who missed buying at $45 may buy if price returns there, creating support.
• Orders: limit orders, stop losses and take profits cluster around obvious levels.
• Self fulfilment: because so many traders watch the same levels, they tend to react there.

How to draw levels#

1. Start on a higher timeframe such as daily or weekly; those levels matter most.
2. Mark clear swing highs and lows where price turned sharply. See Swing Highs and Lows.
3. Look for repeated reactions: places where price turned more than once.
4. Draw zones, not lines. Mark an area that covers the wicks and bodies of the reactions, for example $49.60 to $50.10, instead of an exact price.
5. Keep only the important ones. Five clear levels are more useful than twenty faint ones.

What makes a level strong#

See Level Strength and Clustering. Note that each test can also weaken a level by using up the orders resting there, which is why levels that are hit repeatedly often eventually break.

Trading support and resistance#

Bounce trades#

Buy near support or sell near resistance, ideally after a sign of rejection such as a long wick or engulfing candle, with a stop just beyond the zone. See Engulfing Patterns and Hammer and Hanging Man.

Breakout trades#

When price closes decisively through a level, trade in the direction of the break, often waiting for a retest. See Breakouts.

Role reversal#

Broken resistance often becomes support, and broken support becomes resistance. See Role Reversal and Retests.

Levels on the TradeLabs AI chart#

Drawing levels by hand is an essential skill, but checking your work against an automated view helps. The TradeLabs AI chart has an Auto Analyze feature that marks key levels on the candles in view, so you can compare its levels with your own.

Common mistakes#

• Drawing exact lines and expecting price to stop to the cent.
• Marking too many levels, so every price is near "a level".
• Buying support in a strong downtrend where levels break one after another.
• Placing stops exactly at the level, where many other stops sit.
• Ignoring the higher timeframe levels that matter most.

Some traders calculate levels mechanically from the prior session's prices with Pivot Points, which often line up with visible support and resistance.

Frequently asked questions#

What is support and resistance in trading?#

Support is a price area where buying has tended to halt declines; resistance is where selling has tended to halt rallies.

How do you identify strong support and resistance?#

Look for levels on higher timeframes with multiple clear reactions, heavy volume and confluence with other levels such as round numbers.

Do support and resistance levels always hold?#

No. They are areas where reactions are more likely, not guarantees. Always use a stop and accept that levels break.

Next, compare horizontal levels with moving ones in Static vs Dynamic Levels.
