What is the buy sell tax on Unibot?

Excuse me, I'm a bit confused about the tax implications of trading on the Unibot platform. Could you please clarify what the buy-sell tax is on Unibot? Is it a flat rate, or does it vary based on factors like transaction size or the type of cryptocurrency being traded? Also, are there any other fees or charges that I should be aware of before making a trade on Unibot? I appreciate your help in clarifying this matter.
