Swing Trading With Fibonacci: Retracement Zones That Earn a Trade

Sixty minus 12.36 is 47.64. That subtraction is the whole of the 61.8% retracement on a $20 swing from $40 to $60, and it is worth doing by hand once, because it shows there is nothing mysterious inside a Fibonacci level. It is a fraction of a range, subtracted from the high. What makes the level worth trading is what happens when price gets there.

The retracement levels, worked

Take a hypothetical stock. It rallied from a swing low of $40 to a swing high of $60. The range is $20. Each retracement level is that range times the ratio, taken off the high.

The Fibonacci retracement calculator does this for any pair of prices. The harder part is choosing the pair, and the guide to drawing Fibonacci retracements covers which low and which high to anchor on, whether to use wicks or closes, and what to do when two different lows both look like the start of the move.

Why the entry waits for a close in the zone

Read 38.2% to 61.8% as a band. A limit order resting on $47.64 buys every stock that reaches it, including the ones falling straight through on their way to $42. So wait.

What you want to see is price proving itself inside the zone. One sign is a daily close back up after an intraday dip into the band, which means sellers pushed price into the level during the session and could not keep it there by the close. On the hourly chart, a higher low forming after the first touch is another. Either one tells you that someone bought the level and the sellers who drove the pullback have eased off, and it costs you a slightly worse price than the limit order would have paid, in exchange for skipping the trades where the level never held at all.

The uptrend filter matters for the same reason. If the stock sits below a falling 50-day average, the rally from $40 to $60 may have been a bounce inside a larger decline, and a retracement of a bounce is a poor place to buy.

The trade, from entry to extensions

Say the stock dips to $47.20 intraday. Then it closes at $48.00 with a bullish candle. That close is the signal.

The stop goes below 78.6% because a pullback that deep has retraced most of the move, and past that point the rally has mostly been given back, taking the reason for owning the stock along with it.

Size from the $4.00. If you are willing to lose $400 on the idea, that is 100 shares; at $200, it is 50. The stop is fixed by the chart, so the only thing you adjust is the share count. Moving the stop up to $46 to buy more shares puts it inside the zone you just said buyers would defend, and a normal second dip into that zone would take you out of a trade that was still working.

Sometimes the stock clears $60. Extensions then give you places to take more off. They are measured from the swing low, using the same $20 range.

A common way to handle it: sell part at $60, move the stop on the remainder up to your entry or just under a recent higher low, and trail it toward $65.44 and then $72.36.

Why it works when it works

The ratios have no power over price. A stock does not know what 61.8% of its last swing is. What the ratios do have is an audience. Many traders draw the same lines on the same obvious swings, so buy orders, stops and profit targets cluster near them, and when enough orders sit in one place, price reacts there often enough to be worth watching.

That also explains the rule about clear swings. On a chart where the low and high are obvious, most traders anchor to the same points and the crowd lines up. On a messy chart, everyone draws something different.

Where the retracement trade fails: chop, gaps and loose anchors

Choppy, sideways markets break it first. With no clean swing there is nothing sensible to measure, and levels drawn across a range get crossed back and forth without meaning anything. News-driven gaps break it too: an earnings miss or a downgrade can open the stock below your stop, and the 78.6% line gives no protection against a price that never traded between yesterday’s close and today’s open. Then there is the chart with several plausible anchors, where your choice of swing decides the answer before the market has a say.

For more setups that use the same chart reading, see technical analysis. If the swing is clean, the trend is up and a close in the zone shows buyers, the trade is worth taking. Remove any one of those conditions and the levels are only lines.
