A three-check drill for support and resistance

Support below, resistance above

Support sits below the market. It can be marked from a prior trough, a moving average, or a trendline as a level a decline has so far failed to penetrate. Resistance is a ceiling above the market, often a horizontal or near-horizontal line across several tops, where selling is described as strong enough to interrupt or reverse an advance.

Support and resistance are a chart condition drawn from prior troughs, peaks, trendlines, or moving averages on open-high-low-close structure. They are used as a falsifiable hypothesis rather than a guaranteed wall.

The paragraphs that follow restate the historical workflow. The three-check drill is an editorial reading of that workflow, not a claim made by the archive.

The QQQ ceiling and the later stall

On the same QQQ chart, mid-October, early-November, and early-December rallies failed to close above 36 until late December, when buying finally carried prices through that ceiling.

In the mid-January 2004 QQQ decline from about 39, prices stalled near 36.25 where a 50-day exponential moving average coincided with a horizontal line from prior December and November peaks. That stall sat where the moving average met a horizontal line taken from those earlier peaks.

A close confirms a break

A close beneath support is treated as a break that lets the decline resume. A bounce that holds is treated as a successful test and an early sign the downtrend may be ending.

Breakout confirmation is a close through a prior support or resistance area. That close converts the old boundary into a new hypothesis on the opposite side of the market. Editorial reading: treat only a close through the area as breakout confirmation.

Role reversal on the first pullback

After prices break through a prior resistance area, that same level can later act as support on the first pullback. Role reversal is that tendency: a broken resistance area can act later as support on a pullback, or broken support can act later as resistance.

Editorial reading: after the breakout, the idea is not finished until that first retest either holds or fails.

Tighten the stop before the test

As price nears a support or resistance area, tighter real or mental stop-loss orders are presented as a way to bound damage if the level fails. A stop-loss order is a real or mental risk bound tightened as price approaches a nearby support or resistance test so a failed level stays a limited loss.

Editorial reading: place or tighten that bound before the test arrives, not after the level has already given way.

Longer charts and longer-lived areas

A pause that looks unexplained on a 15-minute chart may match support or resistance visible on an hourly or daily chart, and longer-horizon levels are treated as more powerful than shorter-horizon ones. Time-frame confirmation is that check of a longer chart horizon.

No indicator is offered that can measure how strong a support or resistance area will be. A longer-lived area is treated as more likely to hold.
