What does FT mean in buy and sell?

Could you please clarify for me what the abbreviation 'FT' stands for in the context of buying and selling? I've seen it mentioned in some financial transactions but I'm not quite sure what it signifies. Is it related to a specific type of transaction, a market term, or perhaps a unit of measurement? Could you provide some insight into its meaning and usage in the realm of finance and cryptocurrency? Thank you in advance for your assistance.
