Reading support and resistance: reaction zones, breakouts and retests

Support is an area where falling price may react; resistance may obstruct rising price. Find prior highs/lows and repeated reactions, then see what happens as current price approaches.

Worked example: does touching 118–119 count as a breakout?

Suppose a teaching chart shows repeated pullbacks around 118–119, and the latest candle reaches 119 but closes at 116. The visible fact is a touch of candidate resistance followed by a close below, not an established breakout. A later close above the zone warrants checking whether price holds there; a retest can only be described after price actually returns. These are fictional teaching values, not trading levels.

Step 1: find candidate zones at previous highs and lows

Group nearby points where price stopped falling, met resistance or repeatedly changed direction into a zone. Below the current price, it is potential support; above it, potential resistance.

Step 2: use zones rather than one precise price

Candle highs/lows need not coincide exactly, and screenshots may not reveal every price clearly. Zones preserve those differences. Do not ignore reactions just to pick a round number.

If the price axis is blurry, describe relative locations such as near the previous high and verify values in the original charting software. AI markers need the same check.

Step 3: distinguish the middle and edges of a range

When price repeatedly moves between similar bounds, watch the upper and lower edges. In the middle, reactions may occur on either side. A brief rise does not turn the whole range into a clear uptrend.

Confirming a breakout: the close, then what follows

When price crosses resistance, first check whether the candle has closed, then its close and whether price stays outside the zone. Check volume if clearly shown; otherwise mark volume evidence unknown.

Retest or false breakout?

Returning to former resistance after a breakout is a retest scenario; whether support forms depends on the reaction. A quick return inside the old range calls the breakout reading into question.

What information should a stock candlestick screenshot include?

Keep the instrument, timeframe, enough past price action and price axis, plus volume if available. Verify positions on the same complete screenshot; a daily reaction zone is not an exact boundary on another timeframe.
