Support and resistance: how to find the levels on a chart

Why prices turn at the same place

A level forms because people remember prices. If a stock bounced at $50 three times, buyers who missed those bounces may wait for $50 again, and sellers who held on may decide to sell if it ever gets back to $60, the price where it kept stalling. Neither group is certain; they are reacting to the same memory. That is all a level is: a place where enough orders gathered in the past to turn price around.

The practice charts above show a range: price bounces between a floor and a ceiling. Real charts are rarely that tidy, which is why the rules matter.

Zones, not lines

Two traders drawing the same support will rarely pick the same cent. One uses the wicks, another the closes, a third the bodies. Treat a level as a band a little above and below your line. That is why the exercise accepts any line inside a zone instead of one exact price, and why a wick that pokes through a level for one candle does not, by itself, mean the level is gone.

When support becomes resistance

When price finally closes clearly below a support, the old floor often acts as a ceiling on the way back up. Traders call it role reversal. The logic is the same memory effect: people who bought at the old support and now hold a loss may sell when price returns there. It is a tendency, not a rule; plenty of broken levels are crossed again without a pause.

Breakouts and fakeouts

A close through a level is called a breakout. Many breakouts fail: price closes beyond the level, then returns inside the range within a few candles. That is a fakeout. There is no reliable way to tell the two apart in advance. Waiting for a close (not just a wick) and for a second candle helps you avoid some fakeouts, at the cost of reacting later to real breakouts.

Where the idea is proven wrong

This is where support and resistance earn their place in risk management. If your reason to expect a bounce is support at $50, a close well below the support zone says that reason is gone. Traders who use levels usually decide in advance where that is, and place a stop order just beyond the zone rather than exactly on the line, where normal noise would trigger it. A stop does not guarantee the exit price: in a fast market or a gap, the order fills at the next available price. The distance to that stop is also what sets how much you can lose, which is why position size is worked out from the stop, never the other way round: the position size calculator shows the arithmetic.

What support and resistance do not tell you

• When a level will break. Every level holds until it does not. Three touches describe the past.
• How far price will go after a break. Any target drawn from a level is a convention, not a forecast.
• Why the level formed. News, earnings and the wider market can erase a level in one candle.

No reliable statistic says how often a level holds; it depends on the market, the timeframe and how the level is drawn. On this site's simulated charts, levels are built into the chart for practice, so the exercise teaches you to see them, not to trust them.
