1. The Market Philosophy¶
This script operates on a Filtered Momentum philosophy. Its core thesis is that while the Parabolic SAR (PSAR) is effective at identifying trend direction, its raw signals are prone to generating significant noise and false positives in non-trending or weakly trending markets. The strategy aims to generate alpha not by inventing a new signal, but by systematically filtering out the low-probability trades inherent in a basic PSAR system. It presupposes that profitable trends are not only directional but also possess sufficient strength and duration. By layering filters for long-term trend alignment (EMA) and trend intensity (ADX), the script seeks to engage only when the probability of trend persistence is statistically high, thereby improving the signal-to-noise ratio.
2. The Trade Narrative¶
The script is designed to wait for a specific market story to unfold before acting. This narrative begins with the establishment of a clear, macro-directional bias, where price is trading decisively above or below a 50-period EMA. This sets the stage. The second act requires the market to demonstrate conviction; the ADX must rise above a minimum threshold, signaling that the trend is not lazy or choppy but is backed by genuine momentum. Only when this environment of a strong, confirmed trend is present does the script look for its entry cue: a PSAR flip in the direction of the macro trend. This flip represents a tactical opportunity to join a move that is already in progress and has demonstrated its validity.
3. Trigger Logic & Mechanics¶
The strategy’s execution logic is a cascade of confirmations designed to achieve high-conviction entries.
Core Signal & Context: The PSAR flip provides the initial, raw entry signal. However, this signal is immediately qualified by a 50-period EMA. This confluence ensures the trade is aligned with the broader market current, preventing the system from fighting powerful underlying trends.
Strength & Regime Filter: The ADX filter is the most critical component for managing the drawdown profile. By requiring an ADX value above 15, the script acts as a regime filter, effectively deactivating itself during low-volatility, range-bound conditions where momentum strategies typically underperform.
Final Catalyst: The confluence of a PSAR flip, alignment with the EMA, and confirmation of trend strength from the ADX serves as the final catalyst. This multi-factor agreement transforms the script from a passive observer into an active participant, executing a trade only when a tactical entry point appears within a strategically favorable market structure.
