end of day

Here is the strange part. The Nigerian Exchange in Lagos does not actually stop trading the moment the closing bell feeling arrives. There is a small window, often called the closing auction or closing session, where orders still get matched, and the very last trade struck in that window becomes the official End of Day price, even though the market has technically already been winding down for several minutes. So the number you see splashed across news apps at close of business is not simply whatever the price happened to be at 2:29pm. It is a deliberately settled figure, almost like the market takes a breath and agrees on one final answer before everyone goes home.

This matters more than it sounds. Pension fund managers in Lagos who value your RSA balance daily use End of Day prices, not the flickering prices you might have seen mid afternoon on a stockbroker's app. So if MTN Nigeria shares wobbled up and down all day and settled at ₦210 by the close, that ₦210 is what feeds into every valuation, every index calculation, and every headline about the market gaining or losing points that day.

In London, the same idea exists at the London Stock Exchange, where the closing auction sets the official close used to calculate the FTSE 100 level for the day, which then affects everything from index tracking funds to pension statements read by Nigerians living and working across the United Kingdom.

For someone in Manchester who invests in Nigerian stocks through an app, or a trader in Lagos glued to their phone, End of Day is the moment the guessing stops and the record book gets its entry. Everything before that is just noise finding its way to an answer.
