Course of Sale & Volume

So I bought some more shares today to top up. After my purchase went through, I checked the sell offers again and they hadn’t moved and my trade isn’t listed in ‘course of sale’ or volume section.

I have the shares that I bought but just scratching my head at where they have come from and why isn’t it showing it in the volume or course of sale section.

I am semi-new to this (trading for almost 2 years), just hoping someone can enlighten me as to where I bought the shares from and why isn’t it showing up for the rest of the public to see that shares were bought and sold today.

Thanks in advance.
