what the previous session correlation report measures

walks through historical sessions and tags each as green or red, then counts every combination of yesterday's color and today's color. supports open-to-close and previous-close-to-close calculation modes.

the report is available for futures, stocks, ETFs, forex, and crypto. you can filter by ticker, session (NY, London, Asian, full globex, or custom), calculation mode, and lookback period.

how the calculation works

the previous session correlation report compares each session's color to the previous session's color.

• the report iterates through historical sessions and tags each as green or red
• for open-to-close mode, color is set by comparing today's close to today's open
• for previous-close-to-close mode, color is set by comparing today's close to yesterday's close
• it counts every yesterday-today color combination (green→green, green→red, red→green, red→red)
• counts are converted to percentages relative to the previous-day color totals
• the output shows how often each pattern continues vs reverses

how traders use previous session correlation data

• building a directional bias for today based on yesterday's close
• knowing whether your ticker tends to continue (trend follow) or revert (mean revert) after a green or red day
• pairing with green and red days and green and red streaks for a multi-session continuation read
• choosing between open-to-close and previous-close-to-close to match how you read swing setups vs intraday setups
• avoiding low-probability bias trades when the historical correlation is close to 50/50

the data doesn't tell you to trade. the previous session correlation report tells you the historical performance of the setup in front of you. what you do with that information is your decision.

results require customization, time, and effort. the numbers change depending on your ticker, session, and lookback period. always check the data for your specific conditions.
