HOW TO USE IT
- Find one clean impulse leg on your chart. That is a single directional move — a swing low up to a swing high in an uptrend, or a swing high down to a swing low in a downtrend. Getting this leg right matters more than anything else here: measure the wrong swing and every level below is wrong.
- Enter the swing high and the swing low. Use the extreme wick prices of that leg, not the candle bodies.
- Set the trend direction. Choose up if the impulse ran from the low to the high (you are looking for a pullback down into support), or down if it ran high to low (a bounce up into resistance).
- Read the retracement levels. These are where a normal pullback may pause — 38.2%, 50%, 61.8% and 78.6%. The shaded band between 0.618 and 0.65 is the golden pocket, the zone most traders watch.
- Use the extensions as targets. The 1.272 and 1.618 levels project beyond the end of the move, which is how you set a target before you enter rather than guessing afterwards.
- Wait for confirmation before acting on a level. Price reaching a level proves nothing on its own — a confirmation candle closing in your direction is what turns a line into a setup.
Worked example. A move from 100 up to 120 gives a 20-point leg. The 0.618 level sits at 120 − (20 × 0.618) = 107.64, and 0.65 at 107.00 — so the golden pocket is roughly 107.00–107.64. New to this? Start with the full retracement guide.
