There are 3 different visual effects for the FXI Moving Average indicator:
1. Red Star = price is within 20 points of the moving average
2. Yellow Star = same as Red Star, AND Stochastic is in oversold or overbought zone
3. Dotted Line = 200ma equivalent on a higher timeframe (ie: H1)
A yellow star means that most of the entry criteria are present - you would still need to wait for a stochastic crossover before entering. Check out the 200MA strategy reference and lesson video here:
