There is no one 'best' moving average for gold trading. Different traders may prefer different moving averages based on their individual trading strategies and preferences. Some traders may find that a shorter-term moving average (such as a 5-day or 10-day moving average) works better for them, while others may prefer to use a longer-term moving average (such as a 50-day or 200-day moving average). It really depends on the trader's personal preferences and what they are trying to achieve with their trading strategy.
