About

Long-only EMA crossover: enter when the fast EMA crosses above the slow EMA, exit on the reverse cross. The two EMAs are plotted on the chart for visual confirmation.

9/21 is the classic short-term pair; 20/50 swings between days.
Raise the gap for fewer, larger signals; tighten it for faster flips.
Combine with an ATR-based stop or a higher-timeframe trend filter.
