What does the indicator add?
Understand indicator inputs, settings, and limitations before treating a chart signal as confirmation.
Start with the calculation behind the line. Our first indicator lesson uses exponential moving averages to distinguish a completed candle-body cross from a wick that only touches the lines.
Questions to work through
What is being calculated?
An exponential moving average gives greater weight to recent prices while retaining part of its previous value. It responds to price changes with a delay. Record the price input, period setting, and timeframe so that comparisons use the same calculation. Fidelity: Exponential Moving Average.
What counts as a signal?
Define the rule before inspecting the outcome. In the three-EMA exercise, the completed candle’s body must span the lines at the closing timestamp. An intrabar touch or a wick-only cross does not meet that particular rule.
Are you counting the same evidence twice?
Three EMAs calculated from the same closing prices share an input; they are not three independent observations. Compare the indicator result with the surrounding price structure and keep the risk-plan check separate.
Start with A Bullish Candle Crossing Three EMAs: What to Check. Review the surrounding market structure. Examples explain the process and do not establish what a market will do next.
