Why buying Nigerian stock is complicated is because of the too many middle link app called Brokers that is supposedly used to help facilitate the buying of the Nigerian stock process.
So you check out this middle link - brokers app look at one that has a fee that you like, they mostly all have broker fee also look at their reputation to then you sign up, fund your account, in the app you will be able to see the Nigerian stock available and buy option or sell if you want to selling
If you don’t want to go through this broker app you just go to invest.NGXgroup.com sign up and you can be able to examine the data there, note most of this broker apps gets their data from NGXgroup.
