Weighted Moving Average (WMA)
A Weighted Moving Average puts more weight on recent data and less on past data. This is done by multiplying each bar’s price by a weighting factor. Because of its unique calculation, WMA will follow prices more closely than a corresponding Simple Moving Average.SMA calculates the average price over a specific period, while WMA gives more weight to current data. EMA is also weighted toward the most recent prices, but the rate of decrease between one price and its preceding price is not consistent but exponential.An exponential moving average (EMA) is a type of moving average (MA) that places a greater weight and significance on the most recent data points. The exponential moving average is also referred to as the exponentially weighted moving average.
- We make use of numpy. arange() method to generate a weighted matrix.
- We perform the multiplication of the weighted data with the Data points.
- Further, WMA is calculated by dividing the multiplied and summation value by the sum of the weights.
- Identify the numbers you want to average.
- Determine the weights of each number.
- Multiply each number by the weighting factor.
- Add up resulting values to get the weighted average.
- WMA = $89.34.

What is the difference between weighted moving average and exponential smoothing?
SMA calculates the average price over a specific period, while WMA gives more weight to current data. EMA is also weighted toward the most recent prices, but the rate of decrease between one price and its preceding price is not consistent but exponential.
What is exponential weighted moving average?
An exponential moving average (EMA) is a type of moving average (MA) that places a greater weight and significance on the most recent data points. The exponential moving average is also referred to as the exponentially weighted moving average.
What is weighted average with example?
For example, say an investor acquires 100 shares of a company in year one at $10, and 50 shares of the same stock in year two at $40. To get a weighted average of the price paid, the investor multiplies 100 shares by $10 for year one and 50 shares by $40 for year two, and then adds the results to get a total of $3,000.
What is weighted average used for?
A weighted average is regularly used to balance the recurrence of the qualities in an informational index or data set. Investors calculate the weighted average of the price that they had paid for their shares. Weighted Average is used in portfolio returns, valuation and inventory accounting.
Which is better EMA or WMA?
EMA, the EMA will react faster to more recent price movements, the SMA line reacts slower. WMA vs. EMA, the WMA reacts faster than the SMA. And the EMA is even faster than the WMA because it gives weight to the latest periods in an exponential way.

What are the disadvantages of using the weighted moving average?
One of the disadvantages of a weighted moving average is that the entire demandhistory for N periods must be carried along with the computation. 11.3 Exponential Smoothing•Exponential Smoothing:Based on the simple idea that a new average can becomputed from an old average and the most recent observed demand.
Should I use EMA or SMA?
Since EMAs place a higher weighting on recent data than on older data, they are more reactive to the latest price changes than SMAs are, which makes the results from EMAs more timely and explains why the EMA is the preferred average among many traders.

Why do we use exponentially weighted average?
The Exponentially Weighted Moving Average (EWMA) is a quantitative or statistical measure used to model or describe a time series. The EWMA is widely used in finance, the main applications being technical analysis and volatility modeling.
What is the difference between average and weighted average?
The average is the sum of all individual observations divided by the number of observations. In contrast, the weighted average is observation multiplied by the weight and added to find a solution.

How do you use weights to data?
In order to make sure that you have a representative sample, you could add a little more “weight” to data from females. To calculate how much weight you need, divide the known population percentage by the percent in the sample. For this example: Known population females (51) / Sample Females (41) = 51/41 = 1.24.
