Pullback (Retracement)
Price doesn't travel in a straight line even when it's going somewhere. It climbs like stairs and moves like waves — pushed back, then forward again. Say Bitcoin runs from $60,000 to $66,000 and then slips to $63,000: it gave back $3,000 of a $6,000 rise. Traders say it 'retraced 50% of the move.' That temporary retreat is a pullback.
Why traders love pullbacks is simple: rather than chasing a price that has already run, they'd rather buy the dip a little cheaper. That's where 'buy the dip' comes from, and treating pullbacks within an uptrend as entry opportunities is one of the most widespread pieces of trading folk wisdom.
There are also conventional numbers for how deep a 'proper' pullback goes — Fibonacci ratios like 38.2%, 50%, and 61.8% of the prior move are famous. But beyond the fact that many people watch the same levels, there's nothing magical about those numbers. Price sometimes pauses near them and sometimes slices straight through.
The genuinely hard problem lies elsewhere: in the moment, you cannot tell whether this dip is a brief pullback or the trend itself reversing. Buy what you believed was a pullback and get a reversal instead, and you've caught a falling knife. The difference is only settled in hindsight, and no line on a chart guarantees it in advance.
So it's safest to take the pullback concept not as a 'buy cheap' trick but as a framework for understanding that price naturally zigzags. Before panic-selling on a single dip — or buying just because something dipped — first count what actually happened at spots like that in the past.
What the data actually shows
Barobara counts and publishes the full historical record of the classic 'catch the dip' signals. Look at the historical record of the RSI oversold signal — the 'sold too hard, too fast' reading — and the historical record of the 3 consecutive red candles signal: afterward, price rose about as often as it fell, close to a coin flip. The 'dip, then bounce' folk wisdom doesn't clearly show up in the data. And even this is only a past distribution, not a number that predicts the next occurrence.
Common misconceptions
"Buying the dip is safe?" Pullback versus trend reversal can only be told apart after the fact. Every point on the way down looks like 'the dip,' and only some of them turn out to have been dips. The fact that price pulled back guarantees nothing by itself.
"Price bounces once it retraces 50% or 61.8%?" Fibonacci ratios are a convention many people glance at, not a law price must obey. The cases where price stopped there stick in memory; the cases where it fell straight through are just as plentiful.
FAQ
Q. How do I tell a pullback from a trend reversal?
There's no reliable way in real time. It's a label assigned in hindsight: if price resumed the original direction, it was a pullback; if it kept going the new way, a reversal. That's why many traders put their energy into deciding in advance where they'll get out if wrong (the stop-loss) instead.
Q. Is a brief rally in a falling market also a pullback?
Yes — a temporary bounce within a downtrend is a pullback too. The market's nickname for it is the 'dead cat bounce.' The phrase is used precisely as a caution: a bounce in a bear market doesn't mean the bottom is in.
