First, let's create dummy time series data and try implementing SMA using just Python. Assume that there is a demand for a product and it is observed for 12 months (1 Year), and you need to find moving averages for 3 and 4 months window periods. Import module import pandas as pd im...

Python: 3.8.5 由于使用了Anaconda,我们需要使用的相关的包已经包含在内了,包括pandas,numpy等等。 Simple moving average(SMA)简单易懂平均是一种最基础的技术指标。简单易懂平均是指,我们把一段时间的价格加起来,除以这段时间的长度就可以得到。简单移动平均的思想是,我们给于每一天同样的权值,因为我们假设不管是...
MovingPandas是一个基于Python和GeoPandas的开源地理时空数据处理库,用于处理移动物体的轨迹数据。关于MovingPandas的使用见文章:MovingPandas入门指北,本文主要介绍三个MovingPandas的绘图实例。 MovingPandas官方仓库地址为:movingpandas。MovingPandas官方示例代码仓库地址为:movingpandas-examples。本文所有实验数据来自于:moving...
In Python, the estimation is: Example of how to use rolling and apply in pandas In pandas, there is no direct method for estimating the Weighted Moving Average. It is necessary to use.rollingand.apply; these components facilitate the implementation of custom functions. ...
使用Python实现Hull Moving Average (HMA) 赫尔移动平均线(Hull Moving Average,简称HMA)是一种技术指标,于2005年由Alan Hull开发。它是一种移动平均线,利用加权计算来减少滞后并提高准确性。 HMA对价格变动非常敏感,同时最大程度地减少短期波动可能产生的噪音。它通过使用加权计算来强调更近期的价格,同时平滑数据。
