If you trade on the spot market and use the LONG algorithm, the profit can only be made in the second coin of the trading pair (there is no other option). For example, for a pair of BTC-USDT traded in a LONG algorithm, the profit will always be in USDT.
If you trade on the spot market and use the SHORT algorithm, the profit coin can be selected when creating/editing a bot. The profit coin can be both the second coin of the trading pair and the first coin. For example, for a trading pair of BTC-USDT in the SHORT algorithm, it is possible to obtain a profit in BTC, thereby increasing the initial deposit of the bot.
If you trade USDS-M futures, then profit with any of the trading algorithms is possible only in the second coin of the trading pair (at the moment it is USDT, BUSD).
If you trade COIN-M futures, then profit is possible only in the first coin of the trading pair (in the bot's deposit coin). For example, when trading the BTC-USD pair, the profit will always be in BTC.
