Relative Strength

7월 7일

Description:
This indicator provides a simplified yet powerful method for measuring a stock's momentum based on its proximity to its recent high. It is a direct implementation of a trading concept discussed in a lecture from the New York Institute of Finance.

Core Concept

The underlying theory, supported by academic research, is that a stock making a new high is one of the most bullish signals possible. Such stocks have a statistical tendency to continue making new highs in the near term.
Instead of requiring complex relative strength calculations against a universe of stocks, this indicator uses a simple and elegant ratio to act as a proxy for momentum:
Indicator Value = Current Close / Highest High of Lookback Period
A value approaching 1.0 indicates the stock is strong and nearing a new high. A value at 1.0 means a new high has just been made.
How to Use This Indicator
The indicator consists of two primary components:
RS Line (Teal): The core momentum calculation (Close / High).
Signal MA (Orange): A moving average of the NHRS Line, which acts as the trigger for signals.
The signals are generated based on the crossover between these two lines:
BUY Signal: When the RS Line crosses ABOVE its moving average. This suggests that short-term momentum is accelerating and a new uptrend may be starting. The background will turn green.
SELL Signal: When the RS Line crosses BELOW its moving average. This indicates that momentum is fading and it may be prudent to exit the position to avoid a decline. The background will turn red.

Indicator Settings
You can customize the indicator to fit your trading style and the timeframe you are analyzing:
High Lookback Period: Choose the period for the "Highest High" calculation. Options range from 1 Month to 12 Months (52 weeks), allowing you to measure short-term or long-term strength.
Moving Average Length: Adjust the length of the signal line's moving average. The lecturer defaults to 26 weeks for a six-month view.
Moving Average Type: Select the type of moving average for the signal line (SMA, EMA, WMA, HMA).

Credits and Inspiration
Proper credit is essential. This script is a practical application of a concept that builds upon foundational academic work.
The core idea that a stock's proximity to its 52-week high is an investable anomaly was detailed in the 2004 Journal of Finance paper:
"The 52 Week High and Momentum Investing" by Thomas J. George and Chuan-Yang Hwang.
The lecturer's contribution, which this script implements, was to simplify this concept into an actionable trading tool by applying a moving average crossover to generate clear and objective buy and sell signals.
