In futures trading, "mini" and "micro" contracts refer to different contract sizes. Mini contracts, like the E-mini S&P 500 (ES), are typically 1/5th the size of a standard contract, while micro contracts, like the Micro E-mini S&P 500 (MES), are 1/10th the size of a mini contract, providing even smaller exposure. For position and risk sizing, it's important to consider your account size and risk tolerance, with a general recommendation to risk no more than 1-2% of your capital per trade.
