zig zag indicator
Zig Zag Indicator is a charting tool that filters out small, noisy price wiggles so a trader can see the real turning points in a stock's movement.
In plain English
Somebody in your family group chat always exaggerates. Fuel price went up by ₦20 and by the time the story reaches the third cousin, it has become 'fuel don double for the whole country'. The small movement gets amplified until you cannot tell what actually happened from what got added along the way.
Stock charts have the same problem. A share price on the Nigerian Exchange can wobble up and down every single day for reasons that mean nothing. Someone sold a small quantity because they needed school fees, someone else bought because they had idle cash. None of that tells you where the stock is really heading, but on a normal chart every wobble looks dramatic.
The Zig Zag Indicator is the calm relative who says, ignore the small talk, tell me what actually changed. It draws a line that only moves when the price shifts by a certain percentage that you decide, say 5 percent or 10 percent. Anything smaller than that gets ignored completely, so the chart shows only the meaningful swings, the real ups and the real downs.
Think of an investor in London tracking a Nigerian bank stock cross listed or watched through an ETF. Instead of reacting to every daily flicker while sipping tea and checking their phone, they use the Zig Zag line to see the bigger swings only, which makes it easier to judge whether the stock is truly climbing or truly falling.
It is not a crystal ball, and it will not predict tomorrow. It only redraws yesterday more honestly, stripping out the noise so the shape of the real story becomes visible.
Traders often pair it with other tools because the Zig Zag line only confirms a turn after it has already happened. It is a historian, not a prophet, but a good historian still helps you understand where you actually stand.
MTN Nigeria's share price moves between ₦210 and ₦225 almost daily on tiny trades. With a Zig Zag Indicator set at 8 percent, the chart ignores all of that and only draws a new line when the price genuinely moves from, say, ₦210 up to ₦230 or down to ₦195, showing the real swings instead of the daily fidgeting.
Questions people ask
Does the Zig Zag Indicator predict future prices?
No, it only redraws past price movement to remove small noise. The last line on the chart can still change as new prices come in, so it should never be read as a forecast.
What percentage setting should I use?
There is no fixed rule. A smaller percentage like 3 percent shows more turns and more detail, while a larger one like 10 percent shows only big swings. Many traders test a few settings against a stock's usual behaviour before settling on one.
Can I use this without other tools?
It works best alongside other signals like volume or momentum readings, because on its own it only confirms turns after they have already happened, which is too late for entering a trade.
