My friend, we cannot trade more than 2-3% risk per trade and I try to trade with 2-3% trading in each trade because forex trading is a very risky trading business in the world and without taking high risks we cannot produce good money here. and Forex traders often ask not to risk more than 2% of their trading par accounts to avoid excessive losses in one trade. While this seems ideal it is also important to note that this is not practical when trading with small account sizes, so the need for large trading capital.
