the open to close range report on edgeful measures how often the close lands within a specified percentage range of the open.

calculates the frequency of "within range" versus "outside range" sessions for any ticker and session, with optional filtering by green or red days.

this is one of the 150+ reports available on the edgeful platform. here's how it works, what the data shows, and how traders use it.

what the open to close range report measures

scans every session in the lookback and checks whether the close finished within your chosen percentage threshold (default 1%) of the open. tracks both directions — close above or below — and produces a within/outside frequency split, with optional green/red day filtering.

the report is available for futures, stocks, ETFs, forex, and crypto. you can filter by ticker, session (NY, London, Asian, full globex, or custom), range percentage threshold, day type (green, red, or all), and lookback period.

how the calculation works

the open to close range report walks every session and tests whether the close stayed inside a percent envelope of the open.

• the report calculates an upper bound (open × (1 + percentage)) and lower bound (open × (1 - percentage)) for every session
• it then checks whether the close finished inside or outside that range
• it tracks counts for within-range vs outside-range
• it records the percentage move from open to close for each session
• it converts counts to percentages so you can see how often price tends to drift small vs go big
• optional green/red filtering isolates only sessions that closed up or closed down

how traders use open to close range data

• setting realistic profit targets — knowing when a 1% move on your ticker is rare vs typical
• avoiding chasing a session that has already pushed past the historical typical range
• building expectations for end-of-day reversion if a session has stretched outside the typical envelope
• pairing with previous days range and session range to triangulate where the close is likely to land
• adjusting position sizing when current price has already extended past the historical close range

the data doesn't tell you to trade. the open to close range 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.
