请问MA的均线是怎么获取的.

def main(): r = exchange.GetRecords(PERIOD_M1) r1 = exchange.GetRecords(PERIOD_M15) r2 = exchange.GetRecords(PERIOD_M30) ma = TA.MA(r,1) ma1 = TA.MA(r1,1) ma2 = TA.MA(r2,999) Log (the number printed out by the test MA: log, ma) Log ((magnitude test MA2 printed out: magnitude, ma1) Log ((magnitude test MA3 printed out: mag, ma2) Log (R) is a number that is printed out in the log (R) test. Log (R1) is the number that is printed in the R1 test: Log ((R2 is a number that is printed in the R2 test: r2)

I want a 7-day average, a 15-day average, and a 30-day average, and I print out a bunch of data, I don't know what that is. A newcomer to the rabbit school is asking for a lesson.
