Which moving average period do you trust, and why that one?

Moving averages smooth price over a set number of periods, and the most common settings were chosen by convention rather than by any law of the market. A period that works on one pair can lag badly on another, and a setting that suited a calm quarter can look too slow in a fast one. The choice is therefore less about the number itself than about how the average behaves on the instrument and timeframe you trade.

Members often disagree on whether to use one average or several, and how to combine them. Some watch the crossing of two averages, others use an average as a zone to judge pullbacks. The question is how you chose your period, and how you check whether it still fits the market you trade. How to trade with RSI covers another tool that members use to judge momentum alongside a trend measure, which is a useful comparison when you test a moving average.

We would like to hear your setting:

• Which period do you use, and did you pick it by testing or by habit?
• How do you tell if a moving average is lagging too far behind price?
• Do you use one average or several, and how do you combine them?
• Have you changed your period after a losing stretch? What happened next?
