What is the maximum number of shares allowed to sell in a single transaction?

Dear fellow investors,
I have a question that i really need to get over as soon as possible.A friend who started investing earlier than i did told me that even though a retail investor can buy as much shares as possible,it is prohibited to sell more than 100,000 shares in a single transaction.
He went further to explain that you need to seek special permission from the regulatory body whenever you intend to sell more than 100,000 shares in a single transaction.He said that this was meant to contain insider trading.
Kindly shed light on this. Thank you all

No such thing @MunyaoTrader.

In our Capital Markets Act, an insider is a person who is reasonably expected to have access to unpublished information, through a direct connection to a company e.g. financial controller, CFO, CEO, director etc.

A takeover notice is only required where you intend to acquire say 25% of a listed company.
