Forex Support & Resistance

Support is a price where falling markets tend to stop and bounce. Resistance is a price where rising markets tend to stop and turn down. These two ideas are the foundation of almost every technical strategy.

What Are Support and Resistance?

Think of price moving inside a room. Support is the floor. Resistance is the ceiling.

Support (floor)

A level below the current price where buying has been strong enough to stop a fall in the past.

Resistance (ceiling)

A level above the current price where selling has been strong enough to stop a rise in the past.

EUR/USD ranges between about 1.0800 and 1.0900. Wicks poke into each zone, but closes stay inside the range.

Example

In the chart above, EUR/USD rose to 1.0904 and 1.0902 and was pushed back both times. It fell to 1.0796 and 1.0797 and bounced both times.

The range is about 100 pips tall (1.0900 − 1.0800 = 0.0100).

Why Support and Resistance Work

Levels are not magic. They work because people remember prices and place orders around them.

Unfinished business — traders who missed the last bounce at 1.0800 place buy orders there "in case it comes back".
Regret — traders who bought at the top (1.0900) and sat in a loss often sell to get out at break-even when price returns.
Stop losses and take profits — many orders cluster just above resistance and just below support.
Big players — banks and funds often work large orders at well-known prices and option strikes.
Self-fulfilling — when enough traders watch the same level, their orders make it matter.

Note: The more times a level is tested, the more traders notice it. But every test also uses up some of the orders waiting there. A level that has been hit five times in a row is often close to breaking.

Zones, Not Lines

Price rarely turns at the exact same pip twice. In the first chart, the tops were at 1.0904 and 1.0902, not 1.0900. That is why good traders draw zones (a band of 10–30 pips on a daily chart) instead of thin lines.

Draw the zone from the bodies (closes) to the wick extremes of the turning candles.
Use thinner zones on lower timeframes and wider ones on higher timeframes.
Place stop losses outside the zone, not inside it.

Tip: If you want to measure zone width in a volatility-aware way, use a fraction of the ATR. For example, a zone about 0.25 × daily ATR wide.

Round Numbers

Round numbers (also called psychological levels) are prices ending in 00 or 50, like 1.0800, 1.0850, 1.0900 on EUR/USD or 150.00 on USD/JPY. They act as support and resistance because:

People naturally pick round prices for entries, stops and targets.
Option strikes and big orders are often placed at round prices.
News headlines talk about "EUR/USD breaks 1.0900", which draws attention.

Level type	EUR/USD example	USD/JPY example	Importance
"Big figure" (00)	1.0800, 1.0900	150.00, 151.00	High
Half figure (50)	1.0850	150.50	Medium
Major round	1.1000, 1.0500	150.00, 155.00	Very high

How to Draw Support and Resistance

Start on a higher timeframe. Open the daily or 4-hour chart. Levels there are watched by more traders.
Find clear turning points. Look for places where price reversed sharply, ideally more than once.
Draw a zone through the cluster of wicks and bodies at those turns.
Keep only the important ones. Two or three levels above price and two or three below is enough.
Check for round numbers nearby. A level that lines up with 1.0900 is stronger.
Move to your trading timeframe and wait for price to reach a zone.

Warning: Too many lines make every price look like a level. If your chart looks like a barcode, delete the minor levels and keep only the ones with clear, strong reactions.

Role Reversal: When Support Becomes Resistance

When price breaks through a level, the level often flips its role. Old resistance becomes new support. Old support becomes new resistance. This is called role reversal or a flip.

1.0900 rejects price twice. After the breakout, price comes back to 1.0900, holds it as support (the retest) and rallies to 1.0970.

Example

Traders who sold at 1.0900 are now in a loss after the breakout. When price returns to 1.0900, many buy back to close their shorts at break-even. New buyers who missed the breakout also buy there. That extra buying turns the old ceiling into a floor.

Retest buy entry   = 1.0905
Stop loss          = 1.0885 (below the 1.0900 zone)
Risk               = 20 pips
Target (prior high)= 1.0945  →  reward 40 pips  →  2R

Breakouts vs Fakeouts

A breakout is when price moves through a level and keeps going. A fakeout (false breakout) is when price pokes through a level and then quickly returns inside.

Price spikes to 1.0918 and even closes above 1.0900, but the next candle falls back to 1.0888. Breakout buyers are trapped and price drops 80 pips.

Signs that a breakout is more likely to be real:

A strong candle closes clearly beyond the zone (not just a wick).
The break happens during an active session (London or New York), not in the quiet Asian hours.
The break is in the direction of the higher-timeframe trend.
Price had been squeezing against the level (higher lows into resistance).
A follow-through candle or a successful retest comes next.

Warning: Big news releases often cause fast spikes through levels that reverse within minutes. Check the economic calendar before trading a breakout. See Trading the News.

Trading Bounces vs Breaks

	Bounce (range) trade	Break (breakout) trade
Idea	The level holds	The level fails
Best market	Sideways range	Trend, or after a long squeeze
Entry	Rejection candle at the zone (e.g. a hammer or engulfing)	Close beyond the zone, or the retest after it
Stop loss	Just beyond the zone	Back inside the old range
Target	The other side of the range	Next level, or a measured move
Main risk	The level finally breaks	Fakeout

Tip: The retest entry is a middle path. You wait for the break, then enter when price comes back to the flipped level. You miss some moves that never retest, but you avoid many fakeouts and get a tighter stop.

Test Yourself With Exercises

What usually happens to an old resistance level after price breaks clearly above it?

It disappears and no longer matters
It becomes stronger resistance
It often acts as new support

This is role reversal: broken resistance often becomes support on a retest.

Why do traders draw support and resistance as zones instead of thin lines?

Price rarely turns at the exact same pip twice
Zones look nicer on the chart
Brokers require it

Turns happen in an area. A zone captures the wicks and bodies around the level.

EUR/USD ranges between support at 1.0800 and resistance at 1.0900. You buy at 1.0810 with a stop at 1.0785 and a target at 1.0890. What is your risk:reward?

1 : 2
1 : 3.2
1 : 4
1 : 1

Risk = 1.0810 − 1.0785 = 25 pips. Reward = 1.0890 − 1.0810 = 80 pips. 80 ÷ 25 = 3.2.

Price wicks above resistance, then closes back below it on the next candle. What is this called?

Role reversal
A retest
A round number
A fakeout

A break that quickly fails is a fakeout (false breakout).

Which price is most likely to act as a psychological level on USD/JPY?

150.37
150.00
149.83

Round numbers like 150.00 attract orders and attention.
