trend line

Think of a trend line like the line a mother draws in her head watching her child's height marked on the wall every birthday. Some years the mark jumps more, some years less, but if you step back and follow the marks from age five to age fifteen, they climb steadily upward. That imaginary line running through all the marks is the trend. You are not looking at any single jump, you are looking at the general direction.

On a stock chart, traders do the same thing with prices instead of height marks. If a share on the Nigerian Exchange, say Dangote Cement, has been closing higher week after week even with small dips here and there, an investor can draw a line connecting the low points of each dip. That rising line is an uptrend line, and as long as the price stays above it, the story is still one of growth.

The same works in reverse. If the price keeps making lower highs, a falling trend line connects those highs, and it tells you the market currently favours the sellers. Traders on the London Stock Exchange watching a stock like Tesco use the exact same drawing on a chart to decide whether to hold on or step back.

A trend line is never a promise. It only describes what has been happening, not what will happen next. The real value comes when the price finally breaks through the line, because that break often signals that the mood of the market is changing, and sharp traders watch for it closely.

For someone abroad sending money home through an investment app, a trend line on a Nigerian stock or a foreign index can help decide timing. It will not remove the guesswork, but it gives a calmer, visual way to see whether a price is generally climbing, falling, or just moving sideways without much conviction.
