CONCEPT

Support and resistance: why price bounces

Two invisible lines where supply and demand change hands. The most basic and most useful map on the chart.

SUPPORT

floor

where the drop halts

RESISTANCE

ceiling

where the rise halts

THE KEY

memory

price remembers levels

THE IDEA

2 lines

a floor and a ceiling

Support is the level where a decline tends to halt because buyers step in. Resistance is the ceiling where a rise stalls because sellers step in. It's not magic: these are zones where many participants made decisions before and remember them.

SIMPLE RULE

TO GET IT

2

2

the only two things a level does

Hold (bounce) or break (breakout). All of technical analysis turns on that binary question.

At a key level, price has only two possible answers. Knowing which to expect, and what to do with each, is half the battle.

BOUNCE
Price touches a level and turns the other way.
BREAKOUT
Price cuts through the level and keeps going the same way.

THE IDEA

TO REMEMBER

Price has a memory

A level isn't a magic line: it's the memory of thousands of decisions that switch back on when price passes through.
Ronfy Analysis · Editorial

Levels work because people remember where they bought or sold. That collective memory turns into real orders that halt price.

PRICE MEMORY
The market's tendency to react at levels where it already reacted before.
ORDERS
Buy or sell instructions that pile up at specific levels.

EXAMPLE

SAMPLE CHART

Three touches and a break

SUPPORTBOUNCEBOUNCEBREAKBREAK
TEST 1TEST 2TEST 3BREAK

Each bounce confirms the level, but also wears it down. The more times a support is tested, the weaker it gets.

An illustrative example, not a real asset. Price tests the same floor three times and, on the fourth, breaks it.

TOUCH
Each time price reaches a level and reacts.
WEAR
The loss of strength of a level after being tested several times.

THREE KEYS

WHAT MATTERS

Three things to know about levels

  1. THEY FLIP

    When a support breaks, it usually starts acting as resistance (and vice versa). It's the 'polarity change': yesterday's floor is tomorrow's ceiling.

  2. ROUND NUMBERS WEIGH

    Round numbers (100, 1,000, 50,000) act as magnets: everyone watches them at once, so that's where orders pile up.

  3. BEWARE THE FAKE

    Not every break is real. A 'fake breakout' crosses the level for a moment and slips back inside. Volume helps tell the good one from the trap.

With these three ideas you stop seeing the chart as random lines and start reading the logic behind it.

POLARITY CHANGE
When a broken support starts acting as resistance, or vice versa.
FAKE BREAKOUT
An apparent break of a level that quickly reverses.

ANATOMY

WHAT MAKES A LEVEL STRONG

Why some levels hold better than others

NUMBER OF TOUCHES35%

The more times it's respected, the more the market watches it

VOLUME AT THE ZONE30%

Heavy trading there = many orders anchored

TIME RESPECTED20%

A level that holds for months weighs more than a one-day one

ROUND NUMBER15%

Round numbers pull attention and orders

A support touched many times, with volume and respected over time, is the one that truly matters to watch.

Not all supports are equal. These are the factors that give one strength. Weights are illustrative, not an exact formula.

VOLUME
The amount traded; it confirms whether a level has real participation behind it.
ANCHORED
Orders piled up at a level that halt price when it arrives.

TO PRACTICE

6 EXAMPLES

Where to watch levels in practice

SPY~640 n/aThe S&P 500. Multiples of 100 tend to act as psychological magnets.
QQQ~560 n/aNasdaq-100. Very technical: it respects moving averages and round numbers.
IWM~230 n/aSmall caps. Wide range: a good lab for support and resistance.
TLT~90 n/aLong US Treasuries. Round levels mark clear decision zones.
GLD~400 n/aGold. Its 200-day is a textbook support-resistance that many follow.
BTC~80k n/aBitcoin. Big round numbers (80k, 100k) concentrate orders to an extreme.

Liquid assets where levels show up clearly. Prices rounded for illustration, not the day's quotes.

LIQUID
An asset with heavy trading; you buy and sell without moving the price much.
MA200
The 200-day average; it often works as dynamic support or resistance.
ILLUSTRATIVE
An approximate example to grasp the idea, not a figure for the day.
