Seasonality Screener Best Long & Short Patterns Auto-Scan

The Seasonality Screener automatically scans a market’s history to find the most profitable seasonal patterns in the days ahead.
It searches for both long and short setups and shows you the two best patterns based on historical performance.

For each pattern, the screener looks back over past years and calculates:

Average return

Hit rate (win rate)

Winning years vs. total years

The results are displayed in a compact on-chart table with:

Entry date & exit date (calendar days)

Pattern length

Average return & hit rate

Win/trade count

Optionally, the indicator can also draw highlighted boxes in the chart’s history for the selected long and/or short pattern, so you can visually inspect how the seasonal window performed in each year.

You can:

Define how far ahead the screener should look (e.g. next X days),

Control the minimum and maximum pattern length,

Choose how many years of history to use,

And filter by simple regimes such as US election cycle years.

Internally, all calculations are based on daily data, so the seasonal analysis has to be done on the daily timeframe.

This tool is designed as a research and idea generator for seasonal tendencies and should be used together with your own risk management and trading plan.
