Fibonacci levels

A Fibonacci tool takes a completed price move and splits it into set fractions. On a chart, you draw from the low to the high of that move, or from the high to the low. The tool then places lines at 23.6, 38.2, 50, 61.8 and 78.6 per cent of the distance. The 50 per cent line is not a Fibonacci number, but it is included because half of a move is a natural reference point. These lines sit inside the range, showing possible pullback levels.

The numbers come from a sequence where each number is the sum of the two before it. Dividing a number by the next one gives roughly 0.618, and by the one after that gives roughly 0.382. The 23.6 per cent comes from dividing by a number three places ahead. These ratios appear in many fields, but on a chart they are simply fixed divisions. They do not predict where price will go. They only mark prices that are a set fraction of the last move.

On USD/ZAR, a move from 18.0000 to 18.4100 is 4,100 points. The 38.2 per cent line sits 1,566 points below the high, at 18.2534. The 50 per cent line sits 2,050 points below, at 18.2050. The 61.8 per cent line sits 2,534 points below, at 18.1566. Each level is just arithmetic. What gives them attention is that many people watch the same numbers.

Traders choose the same swing highs and lows because those points are easy to see. A clear peak or trough stands out, so thousands of people draw from it. That means the 61.8 per cent line from a well-known move can be the same price for many participants. When a price level is shared, orders tend to gather there. Some will be buy orders, some sell orders, but the concentration is what makes the level noticeable.

This clustering is the only reason the lines can matter. If nobody watched them, they would be no different from any other price. But because people do watch, price often reacts when it reaches one. That reaction might be a small pause or a sharp turn. It might also be nothing at all. The line itself does not force price to do anything. It is just a place where activity may increase.

A common error is to treat a Fibonacci line as a signal. It is not. It is a price where other people may have placed orders, and that can change from one day to the next. Instead, wait for price to actually react at the line, then look for a second reason such as a candle pattern or a prior support level. If price passes straight through, the line did nothing and you move on.

A Fibonacci level on its own tells you very little. Its value comes from what else is happening at that price. If a 61.8 per cent line sits near a previous support level, more people may be watching that area. If it also lines up with a round number like 18.2000, the effect can be stronger. You are looking for a group of reasons, not one line. The more independent factors that point to the same price, the more attention it may get.

Price reaction is the key. When price reaches a level, watch how it behaves. A long candle that closes beyond the line suggests the level is not holding. A small candle with a long wick, or a pattern like a hammer, suggests some buyers or sellers are active there. You do not need to act on the first touch. You can wait for the next candle to confirm. If there is no clear reaction, there is no reason to be involved.

On USD/ZAR, one rand of movement on a 0.10 lot position is worth roughly R1,000. The distance between the 38.2 and 61.8 per cent lines in the earlier example is 968 points. That is about R968 on 0.10 lots. This is why position size matters. A stop placed just beyond a Fibonacci line can be wider than you expect. Always check the contract specification, because the rand value of a point varies between brokers and account types. Some brokers charge commission on top of the spread, and spreads differ.
