Direct trading enables algorithms to trade directly between tokens that have a liquidity pool on PancakeSwap. This decreases the fees significantly for each trade on non-BNB pairs. Thus pairs such as BUSD/BTC or ETH/BTC will be able to trade directly and not through WBNB. This however is only possible if a LP is available, and therefore only a limited amount of pairs can be traded this way. Still, we have noticed that most algorithms on the Mercor platform so far use pairs that can utilize this feature, and therefore it will become the default option for all algorithms.
