A trading model that identifies a reversal in the optimism index
The model applies an 84-day range rank to the 10-day moving average of the Optimism Index for the LIT ETF. The range rank indicator measures the current value relative to all other values over a lookback period. 100 is the highest, and 0 is the lowest. The pessimistic reset condition occurs when the range rank for the Optix Index crosses below the 5th percentile. A new buy signal triggers when the range rank exceeds the 89th percentile, and ETF momentum turns positive within 5 days of the cross.
