Option Levels plots key strike levels directly on your price chart as horizontal lines, based on options volume, gamma exposure, or open interest. These levels highlight where the most significant options activity is concentrated, helping you identify potential call walls, put walls, and other structurally important price zones.

Note: Option Levels is available on NDX, QQQ, SPY, and SPX.

How to Add Option Levels

1. Open an NDX, QQQ, SPX or SPY chart in DeepGamma Web

2. Click Indicators in the Menu Bar

3. Click the green Add indicator button at the bottom of the panel

4. Open the Options tab and search for Option Levels

5. The indicator is added to your chart and appears in the Indicators panel

6. Click the gear icon next to Option Levels to open its settings

   

You can also turn it on or off from Call / Put Levels in the Settings quick bar.

Understanding the Indicator

Option Levels plots horizontal lines directly on your price chart, based on your selected data source. The number of levels shown depends on your Number of levels setting. Each level is ranked by strength using triangle markers, and more triangles indicate a stronger concentration at that strike.

Each level is labeled based on your selected data source and expiration filter. Green levels with downward triangles represent positive values, while purple levels with upward triangles represent negative values.

In addition to the ranked strike levels, Option Levels also plots the Zero Gamma level as a static horizontal line, shown in yellow by default. Unlike the ranked levels, this line is not tied to the Number of levels setting. It always represents the single price point where dealer gamma exposure flips from positive to negative. This is the same concept used in Option Envelopes, just shown here as a flat reference line instead of a shifting envelope.

Understanding Key Terms

Before choosing a data source, it helps to understand a few core options concepts:

• Call - An option that gives the buyer the right to buy the underlying at a set price. Traders buy calls when they expect price to go up

• Put - An option that gives the buyer the right to sell the underlying at a set price. Traders buy puts when they expect price to go down

• Gamma - A measure of how much an option’s delta changes as price moves. High gamma means dealers need to hedge more aggressively as price approaches a strike, which is why gamma concentrations often act as support or resistance

• OI (Open Interest) - The total number of option contracts currently open and not yet closed or expired

• Gamma (Call - Put) - Net gamma exposure calculated using the standard assumption that market makers are long calls and short puts

• Call/Put Σ - Raw call and put options volume, with no gamma weighting

Settings

The settings window has two sections: General and Plot Settings. After making changes, click Apply to update the chart.

General

• Data Source - Choose how the levels are calculated. Options available:

  • Gamma (call - put) (default) - Calculates levels based on net gamma exposure, showing where dealer hedging pressure is most concentrated.
    Use this when : you want a gamma-weighted read on positioning and market regime, similar to what you would use to read Option Envelopes

    
    

  • Call / put ∑ - Calculates levels based on total call and put volume, showing classic call wall and put wall levels.
    Use this when : you want a simple read on where the most contracts are trading, regardless of gamma weighting

    
    

  • OI (eod) - Calculates levels using the prior session’s end of day open interest data, showing structural levels based on standing positions rather than the current session’s live trading activity.
    Use this when : you want a structural view based on standing positions from the previous session’s close, rather than live intraday trading activity

    
    

  • Gamma (call OI-E - put OI-E) - Calculates levels based on the difference between call and put end of day open interest, multiplied by the gamma greek. This gives a gamma-weighted read on standing positions rather than live volume.
    Use this when : you want a gamma-weighted view of dealer exposure based on standing open interest instead of current session trading activity

    
    

• Expiration - Filter levels by expiration. Options available: Default, 0 DTE, <= 1d, <= 7d, <= 31d, <= 91d, All expirations

Note: When Expiration is set to Default, it uses the expiration selected under Expirations in the Settings quick bar.

• Include Carry or Open interest - When enabled, includes open interest carried over from previous sessions in the calculation, giving you a broader view of total positioning. When disabled, only current session data is considered. Default is enabled

• Number of Strikes (0 - unlimited) - Sets how many strikes out from the current price to include in the calculation. A value of 0 includes an unlimited number of strikes. Default is 0

Plot Settings

• Number of sessions - Set how many previous sessions the levels are extended across. Default is 1

• Number of levels - Set how many levels are plotted on the chart. Default is 2. Each level is ranked by strength using triangle markers. Showing more levels means more strikes are ranked and compared against each other

  

• Extension mode - Choose how the level lines are extended. Options available:

  • None - No extension, levels are plotted only for the current session

  • Till interaction (default) - Extends the line until price interacts with it

  • Till end window - Extends the line to the end of the visible chart window

• Text size - Set the font size for the level labels. Default is 11

• Text color - Set the color of the level labels. Default is light gray-blue

• Custom header - Add a custom label text to the levels if needed

• Align previous values on right - When enabled, aligns labels for previous session values to the right side of the chart. Default is enabled

• Align current values on right - When enabled, aligns labels for current session values to the right side of the chart. Default is disabled

• Positive color - Set the color for positive levels. Default is green

• Negative color - Set the color for negative levels. Default is purple

• Zero color - Set the color for the Zero Gamma static line. Default is yellow

• Lines width - Set the thickness of the lines. Default is 1

• Lines style - Choose the line style. Options available: Solid, Dash, Dot, Dash dot, Dash dot dot. Default is Solid

  

Example - How to Use Option Levels

Once added to your chart, you will see horizontal lines plotted at key strike levels, each ranked by strength using the triangle markers. Here is a simple way to use them:

• The number of triangles tells you how significant that level is relative to the others on your chart. A level with more triangles represents a stronger concentration than one with fewer

• The Zero Gamma line gives you the broader regime context. Price above it tends to mean a calmer, more compressed market, while price below it tends to mean a more volatile, directional one. This is the same reading you would apply to Zero Gamma on Option Envelopes

• How price reacts at a level depends on the direction it is approaching from and which side of the market that level represents. Watch for a slowdown, reversal, or acceleration as price reaches the level, rather than assuming a fixed outcome

• Switching the data source between Gamma, Call/Put volume, and open interest can give you different perspectives on the same price action, since each highlights a different type of positioning

• Combine Option Levels with Option Profile to see the full distribution behind the levels, since Option Levels only shows you the top ranked strikes rather than the complete picture

  

Tip: Use Option Levels alongside Option Envelopes for a fuller picture. Envelopes show you the broader zero gamma regime, while Option Levels highlights the specific strikes where activity is concentrated.
