How much are STT charges?

Excuse me, could you kindly clarify for me the exact amount of STT charges that we are looking at here? I understand that STT stands for Securities Transaction Tax, but I'm curious about the specific percentage or fixed amount that is levied on cryptocurrency transactions, especially given the volatility in the market. Is there a standard rate across all platforms, or does it vary depending on the type of transaction and the country in which it's taking place? It would be greatly appreciated if you could provide me with a concise and accurate answer to this query.
