Strategy Overview

The BICORE strategy is a systematic mean-reversion approach applied to the daily chart of Allstate Corporation (ALL). It combines the Elder Impulse System — a dual-condition momentum filter based on EMA slope and MACD Histogram slope — with a classic RSI oversold reclaim exit.

The strategy enters a long position the moment momentum transitions from neutral or bullish into a fully bearish state (the Elder “red bar” cross), then exits once the market demonstrates recovery from oversold conditions as measured by RSI crossing back above 30 with a 5-day lag confirmation window.
