The yellow line is PMA5, the purple line is PMA 10, the green line is PMA20, the blue line is PMA30 and the orange line is PMA60.

That is, yellow is the 5-day moving average, purple is the 10 moving average, green is the 20-day moving average, white is the 30-day moving average, and blue is the 120 moving average (because the trading time for half a year may be around 120 days), so it can also be called the semi-annual line, and red is the 250 antenna, which is also called the annual line.
