Definition
A Linearly Weighted Moving Average (LWMA) is a type of moving average that weighs recent data points more heavily than older data points. Unlike the Simple Moving Average (SMA), where each data point contributes equally to the average, the LWMA assigns higher weighting to more recent values, thus responding more swiftly to price changes. This helps traders to identify trends and price reversals with less lag than the traditional SMA.
The formula for the Linearly Weighted Moving Average (LWMA) is:
\[
\text{LWMA} = \frac{(P_1 \times N) + (P_2 \times (N - 1)) + (P_3 \times (N - 2)) + \ldots + (P_n \times 1)}{N + (N - 1) + (N - 2) + \ldots + 1}
\]
Where:
- \(P\) = Prices over \(N\) periods
- \(N\) = Number of periods

Examples
-
Example of LWMA Calculation:
For a stock with the closing prices of $10, $12, $14, $16 over the last 4 days, the LWMA would be calculated as follows:
- LWMA = [(104) + (123) + (142) + (161)] / (4+3+2+1) = 13.
-
Using LWMA in Trading:
If traders observe that the LWMA is consistently trending upwards, they may consider this a bullish signal. Conversely, if the LWMA starts to slope downwards, traders may look for possible reversal signals.

Frequently Asked Questions
Q: How does LWMA provide less lag compared to SMA?
A: The LWMA prioritizes recent price data, which allows it to react quicker to price trends. SMA averages out past prices, leading to more lag.
Q: Can LWMA be used with other indicators?
A: Absolutely! Use LWMA in conjunction with other indicators like RSI or MACD for a more comprehensive view of market trends.
Q: Is LWMA suitable for long-term investing?
A: Not typically. LWMA is best suited for short-term trading strategies, as it can react quickly to changes in price.
