Flag and Pennant Patterns Explained

The flag and the pennant are trend continuation patterns. Both appear after a sharp impulse, like a short breather before a new push in the same direction. Of all the figures in technical analysis the flag is the one I like most, because it has a clear logic behind it rather than just a pretty picture.

I am cool towards chart figures, I say that often. But the flag is the exception. It is the one formation I genuinely respect, because behind it sits mechanics, not faith in a drawing, and I have been reading the market by volume since 2013. The pennant is its close relative. Below I will go through how they differ and how to trade them, and why even my favourite figure is not a magic signal.

In this article we'll cover:

• the flag and the pennant are a breather after an impulse, not a trend reversal;
• a flag is a parallel channel, a pennant is a small converging triangle;
• the target is measured by the height of the impulse pole from the breakout point;
• I like the flag for its false spike and its clear price projection.

Let me start with the flag, the clearest of these figures.

What Is a Flag Pattern in Technical Analysis?

A flag is a trend continuation pattern where, after a sharp impulse, price enters a small sloping corridor against the move and then breaks out of it and continues in the trend direction.

Let me put it simply. First comes the impulse, which I call the pole: price covers distance sharply and aggressively. If you add volume, on that run it is usually high, and at the bottom you can see a deficit of supply, which is why buyers are forced to lift the price. Then comes the lull: price enters a narrow sloping corridor that runs against the impulse and drifts sideways for a while. That is the flag itself, and volume inside it, on the contrary, falls. The logic here is honest, and that is why the flag is stronger for me than the rest of the figures. A sharp impulse is the footprint of one side being clearly stronger. The pullback in the corridor is a pause, not a reversal: the trend wave stays aggressive while the pullback wave is weak.

What Is a Pennant and How It Differs from a Flag

A pennant is also a trend continuation pattern after an impulse, but its consolidation takes the shape of a small converging triangle rather than a parallel corridor. The difference is simple. A flag has parallel consolidation borders, a narrow sloping channel that you can read as a price channel. A pennant has borders that converge to a point, and the figure looks like a small symmetrical triangle pattern. The pennant is usually tighter and shorter than the flag.

What separates a pennant from an ordinary triangle is that there is always a sharp pole before it, whereas a triangle can form anywhere. In essence these are two versions of one idea: the market made a run, paused to catch its breath, and is getting ready to continue. They work the same way and are traded by the same rules, so from here I will not split them and will cover entry, target and stop for both at once.

How to Trade Flags and Pennants: Entry, Target, Stop

The classic entry is the break of the consolidation border in the trend direction. I do not jump on the first pierce, I wait for a hold and for volume to confirm: if there is no surge of activity on the exit from the figure, I do not trust that breakout. The target is counted by projection. You take the height of the impulse pole and lay it off from the breakout point, because after a pause the market often covers about as much as it covered with the impulse before it. That is a guide, not a promise. The stop logically hides behind the opposite border of the figure, for a flag pointing up that is under its lower border. I keep the risk within 1 to 2 percent per trade, as I am used to. This is how I act, not personal advice for you: each trader sizes the risk to their own account.

Both figures are universal and appear on any market: stocks, forex, crypto and futures. On crypto they are especially frequent because of high volatility, the impulses are sharp and the pole is easy to see. On forex they work too, but I recommend looking for them on higher timeframes, the four hour and above. On the one minute charts it is more often noise that only resembles a flag, and reading the figure step by step is laid out in the flag pattern material.

My Experience: Why I Respect the Flag

Here is the nuance the flag is valued for, and why it is the one figure I respect. Very often, just before the real exit, price makes a false spike: it dips sharply the other way, takes out stops and drags into position those who are trading the wrong direction, then rebounds and goes where it should. For a retail trader that channel pierce is one of the most honest signals there is, because it shows where the liquidity was collected before the move. How it looks on the chart, with the projection and the false spike, I show in the video on how I trade the flag with price projection and the false spike.

And straight to honesty. Even a figure I like does not resolve every time, false exits happen regularly. So I look not at the contour but at what stands behind it: was there an aggressive pole, does volume fall in the pause, was there a false spike before the exit. If none of that is present, what I have in front of me is just a sideways range, not a flag. For a beginner I would advise starting with one instrument and practising the figure on it, because the flag reads cleanest when the pole and the volume tell the same story.
