Ask for the Margin Grid, if the position is Long, for example, the XRP/USDT pair means that we want to get USDT if the price is going up or if we are short and Price going down to get XRP? The capital uses USDT or XRP coins?

Answer

There are 2 option in margin grid, loan USDT or loan Token. Loan USDT means you borrow usdt and need to repaid the USDT again later. This means you need to make profit in USDT with the token, thus buying token with borrowed USDT and sell the token at profit price will give your more USDT. Loan Token means you borrow token and need to repaid the token later. This means you need to make profit in token number, so you short the token (sell the token now) , and buyback the token at lower price. Buying at lower price will give you more tokens amounts.
