Purple is the daily moving average of 10.

Green is the 20-day moving average.

White is the 30-day moving average.

Blue (I don't know what this color is called) is the120th moving average (because the trading time for half a year may be around120th day), so it can also be called the semi-annual line.

Red is the 250 antenna, which is also called the annual line, just like the half-year line.
