There are many reasons why algo trading is becoming popular. The primary one being speed of execution. Since computers operate faster than human brains, they are able to take advantage of split-second opportunities.

Traders use algorithms in trading to mitigate errors and increase their potential profits. 

Investors and traders can either create their own programs or use trading software to carry out trades or they can also copy pre-built strategies available on the platform.

Algo trading also removes human bias, which is the tendency to hesitate or make a different decision than what logic may dictate at the moment. Since algo trading is completely built on logic and programs, there is no scope of human error and it guarrantees on-point execution.
