Later I am calculating the mean. See below the sample code- import numpy as np import pandas as pd file_list = ['test1_1', 'test2_4', 'test3_1', 'test4_3', 'test1_3'] position_data_list = [] for f in file_list: position_data = pd.read_csv(f) position_data_list.append...
import pandas as pd def get_rsi(ohlcv, period, st): ohlcv["close"] = ohlcv["close"] delta = ohlcv["close"].diff() up, down = delta.copy(), delta.copy() up[up < 0] = 0 down[down > 0] = 0 _gain = up.ewm(com=(period - 1), min_periods=period)....

Since calculating the mean is a common operation, Python includes this functionality in the statistics module. It provides some functions for calculating basic statistics on sets of data. The statistics.mean() function takes a sample of numeric data (any iterable) and returns its mean. Here's ...

In this part, we will analyze seasonal forecast data on the go (without downloading and saving the data on the disk). Then, we will look at calculating monthly anomaly (departure of each month from its historical mean state). The data that we will be focusing on is going to be the NMM...
