Buying Dips in Uptrends Without Catching Knives

In a rising market, buying every dip works until it does not. The trade that paid for months becomes the trade that gives it all back, because the dip was the start of a decline. The skill is not in buying dips; it is in deciding which dips qualify.

What makes a dip

A dip is a pullback within an uptrend, which means the uptrend must still be intact when the dip is bought. On the daily chart, that means a higher low has not yet been broken and the slow moving average is still rising. A pullback that breaks the last higher low is not a dip; it is a structural change, and buying it is a bet on a reversal rather than a continuation.

Where to buy

Levels that have supported dips before are the first candidates: a rising moving average that has held several times, the last breakout level, the previous swing high that was overcome. The second ingredient is a sign that selling has slowed: smaller candles, a wick below the level that closes above it, a session that opens weak and closes strong.

Buying the first touch of a level in a fast decline is catching the knife.

The size rule

Each successive dip in a long uptrend deserves slightly less size, not more. Trends age, and the dip that finally fails is more likely the fifth than the first. Confidence should be highest early in a trend, when the structure is fresh, and lowest late, when the moves have become parabolic and the breadth has narrowed.

The stop goes below the dip low, and if the dip low is far away, the size is reduced to match. A stop placed just under the level is inside the sweep zone; a stop placed below the structure is where it belongs.

When to stop buying dips

• The index makes a lower low on the daily chart
• The slow moving average turns down
• Breadth has been narrowing for weeks and a dip is not bought by the broad market
• A dip occurs on a sharp rise in volatility rather than a quiet drift

Any one of these is a reason to wait; two together are a reason to stop.

What to watch

Watch the sequence of higher lows on the daily chart, the slope of the slow moving average, the breadth of the market, and the behaviour of volatility on each dip. A dip that arrives quietly in a broad uptrend is a gift; one that arrives loudly in a narrow one is a warning.
