Introduction
Dr. Alexander Elder's Triple Screen trading system is a effective methodology designed to filter out low-probability trades and to identify high-probability opportunities by analyzing the market across multiple timeframes. The system is based on the principle that the market is too complex to be analyzed on a single timeframe. By combining long-term, intermediate-term, and short-term perspectives, traders can gain a more comprehensive view of the market and make more informed decisions.
This article will explore how to integrate the Force Index (FI) into the Triple Screen trading system. We will discuss how the Force Index can be used at each stage of the Triple Screen process to enhance signal quality and to improve overall trading performance.
The Three Screens of the Triple Screen System
-
First Screen (Long-Term Trend): The first screen is used to identify the primary trend. This is typically done using a long-term trend-following indicator, such as a 100-day or 200-day moving average. The Force Index can also be used for this purpose. A positive 100-day Force Index would indicate a long-term uptrend, while a negative 100-day Force Index would indicate a long-term downtrend.
-
Second Screen (Intermediate-Term Correction): The second screen is used to identify corrections within the primary trend. This is where the Force Index is most commonly used. In a long-term uptrend, a trader would look for a dip in the 13-period Force Index into negative territory as a signal to prepare for a buying opportunity.
-
Third Screen (Short-Term Entry): The third screen is used to time the entry. This is typically done using a short-term indicator or a chart pattern. For example, a trader might wait for the 2-period Force Index to cross back above its centerline before entering a long position.
