algorithmic trading
Algorithmic Trading means using computer programs to buy and sell shares automatically, based on rules, without a human clicking the button each time.
In plain English
The danfo conductor at Ojuelegba does not think before shouting 'Yaba, Yaba, oja, oja' every time the bus slows near a bus stop. It is a rule he follows without stopping to reason it through. Someone shouts the fare, someone gets down, the bus moves. Algorithmic trading works the same way, except the conductor is a computer programme and the bus stops are prices on a stock exchange.
In the old days, a trader at the Nigerian Exchange would watch the screen, feel the market, and call his broker to say 'buy MTN now, price is looking good'. That takes minutes, sometimes longer if the line is bad. An algorithm does not wait for a phone call. It is fed a set of instructions ahead of time, something like 'if Dangote Cement drops to ₦380, buy 5,000 shares immediately', and it acts the moment that condition is met, in less time than it takes you to blink.
This is how big investment firms in London and New York move billions through the London Stock Exchange every single day, faster than any human hand could type an order. In Nigeria, algorithmic trading is still growing, mostly used by institutional investors and pension fund managers who need speed and discipline that emotion cannot always provide.
The beauty of it is that the programme does not panic when the market wobbles, and it does not get greedy and hold on too long hoping for more. It simply follows the rule it was given, again and again, thousands of times a day if needed.
But a computer only does what it is told. If the rule was built on bad thinking, the algorithm will lose money fast and with great consistency. Speed is not the same as wisdom, it just means mistakes happen quickly too.
A fund manager sets a rule that says buy shares of Zenith Bank whenever the price falls below ₦42 and sell when it rises above ₦48. The algorithm watches the market all day and executes that trade automatically, sometimes several times in one week, without anyone lifting a phone.
Questions people ask
Can an ordinary Nigerian investor use algorithmic trading?
It is possible through certain trading platforms and apps that allow automated orders, but most retail investors in Nigeria still trade manually through a stockbroker, since the technology and access needed for true algorithmic trading are usually built for institutions with bigger budgets.
Is algorithmic trading the same as day trading?
No. Day trading just means buying and selling within the same day, done by a person watching charts. Algorithmic trading can happen over any time frame, and the decisions are made by a programme following set rules, not a person reacting in the moment.
Does algorithmic trading guarantee profit?
Not at all. It only guarantees speed and consistency in following instructions. If the strategy behind those instructions is weak, the algorithm will lose money efficiently, which is still losing money, just faster.
