Nine chart studies to learn from

Markets spend long stretches going nowhere. When highs and lows stay inside a narrow band, a rectangle turns that indecision into something you can point at: the top edge is the highest high of the stretch, the bottom edge the lowest low.

The study below searched the recent history for the tightest box that was eventually left behind. The arrow runs from the middle of the range to the first candle that closed outside it; the callout marks that candle.

A close outside a range is a description of what happened, not an instruction. Many breaks fail and price drifts back inside. The habit worth building is marking the range before the break, so the break is judged against a level you chose in advance.

A Fibonacci retracement needs two anchors: where a move started and where it ended. Here the study picked the largest rise in the recent history, from its lowest low to its highest high, and let the tool draw the ratio levels between them.

After a strong rise, price usually gives some of it back. The levels (0.236, 0.382, 0.5, 0.618, 0.786) are a ruler for that give-back, so you can describe a dip as “about half the move” instead of in raw dollars.

The ratios have no special power; they are reference lines. Their value is consistency: measured the same way every time, pullbacks on different symbols and timeframes become comparable.

Divergence is a mismatch between price and a momentum reading. In this study, two swing highs were found where the second high in price is above the first, but the RSI value at the second high is lower than at the first.

The trend line on the price pane connects the two highs. The dotted vertical lines run through the same two candles so you can read the RSI pane underneath and see the lower reading for yourself.

Divergence says momentum behind the move was weaker the second time. It does not say what comes next, and divergences can persist for a long time. Treat it as one observation to weigh against the broader structure.

Support is simply a price where falling candles have repeatedly stopped. To find one objectively, the study collected every swing low in view and grouped the ones that sit within a small percentage of each other.

The horizontal line marks the middle of the largest group; each circle is one of the lows that belongs to it. The more separate visits a level has, the more people are likely to have noticed it.

Levels are zones, not exact prices, and a level that has held several times can still give way. The useful question is not “will it hold?” but “what would it look like if it did not?”

A rising trend line connects at least two swing lows where the second is higher than the first, with no candle closing below the line in between. The study found the most recent pair that meets those rules and extended it as a ray.

Once drawn, the line becomes a reference. Candles that dip to it and close above it are “tests”; a decisive close below it changes the description of the trend from “higher lows” to “no longer making higher lows”.

Two points always make a line, so the first two are only a proposal. Lines earn their place when later price action keeps interacting with them.

Moving averages smooth price into a line that is easier to read than individual candles. Here a 20-period EMA (faster, indigo) and a 50-period SMA (slower, amber) sit on the same chart.

The vertical line marks the most recent candle where the two lines crossed. A crossover means the recent average has moved above or below the longer average; because both are built from past prices, a cross always arrives after the move that caused it.

The slope of the slow average and which side of it price trades on are often more informative than the crossover moment itself. Use the pair to describe the backdrop, not to time anything.

Bollinger Bands widen when price swings grow and narrow when they shrink. The study measured the distance between the bands across the recent history and marked the stretch where it was smallest.

The date-range tool shows how many candles the squeeze lasted. To the right of it you can see how the bands behaved as activity picked up again.

A squeeze tells you volatility was low, not which direction the next move will take. It is a prompt to pay attention, and to mark levels in advance.

A parallel channel is two lines with the same slope. To avoid picking points by eye, the study fitted a straight line through the closing prices of the last 140 candles, then shifted copies of it down to the lowest low and up to the highest high.

Everything inside the channel belongs to the same drift; the dotted middle line is the average path. Candles pressing against one edge show where the stretch was most extended.

Channels drawn after the fact always fit well, because that is how they were built. The honest test is to leave one on the chart and see how new candles treat it.

Average True Range (ATR) is the typical size of a candle, including gaps. Dividing one candle’s range by the ATR just before it tells you how unusual that candle was.

The study scanned the recent history for the candle with the highest ratio and measured it with the price-range tool. The ATR pane below shows how the average reacted afterwards: a single big candle lifts it for a while, then it drifts back.

ATR says nothing about direction. It is most useful for sizing drawings and expectations — for example, whether a level a few percent away is near or far for this symbol right now.
