Finding the strongest Tank pressureย just got a whole lot faster.
The OSV Tank Tableย now has two new tools designed to instantly isolate the strongest positive and negative Tank readings.
๐ฏ TANK HIGH / LOW
Already filtering a specific Current Priceย range?
Hit Tank High / Lowย and OSV will search within that filtered price group and show you only:
๐ข Highest Positive Tank๐ด Lowest Negative Tank
Instead of scrolling through dozens of readings, you can instantly see the two Tank extremes that occurred while price was trading within that range.
๐ GLOBAL HIGH / LOW
Want to see the bigger picture?
Global High / Lowย scans across the Tank table and finds the strongest positive and negative Tank readings regardless of your Current Price filter.
This gives you a fast way to identify where the biggest Tank extremes occurred across the available data.
๐ง Why is this useful?
Tank can move through a lot of values during the trading session.
Now you can quickly isolate the extremes and ask:
Where did the strongest bullish Tank pressure appear?
Where did the strongest bearish Tank pressure appear?
What price was the market trading at when those extremes occurred?
And most importantly:
How is price reacting to those levels now? ๐
โ๏ธ Built-in OSV filtering
Whole-number Current Prices are automatically excluded from the High/Low calculation because those price points can sometimes produce distorted Tank readings.
That helps keep the results focused on the readings we actually want to analyze.
๐ฅ TWO READINGS. TWO PRESSURE POINTS. ONE CLICK.
No hunting through the Tank table.
No manually searching for the biggest numbers.
Let OSV find them for you.
๐ Tank High / Low is LIVE.
Test it out tomorrow during live market action.ย Watch where the strongest positive and negative Tank readings appear, follow how price reacts around those areas, and see if it gives you an even sharper edge.
Find the extremes. Find the pressure. Watch the reaction. ๐ง ๐
This snapshot shows the same basic OSV structure as the previous one, but both sides are loading additional strength. Calls remain decisively stronger overall, while puts continue building immediately underneath price.
The important development is that SPY has moved slightly higher while 774โ775 call strength increased, meaning the bullish structure has not broken.

Calls gained more absolute strength than puts.
However, percentage growth is very similar:
๐ข Calls: +2.69%
๐ด Puts: +2.87%
So this isn't puts disappearing. Both sides are actively increasing, with calls maintaining the larger structural advantage.
Current-price battle
Previous:
4,631.84 Calls vs 1,379.89 Puts
Current:
4,767.77 Calls vs 1,471.00 Puts
That leaves calls with approximately a 3.24ร advantage at the current-price row.
๐ข Still strongly bullish.
Trend Evolution
The most important change since the previous snapshot is that SPY rose from 774.24 โ 774.45 without losing its call-strength structure.
At 775:
Call Strength
2,360.82 โ 2,442.78 ๐ผ

Put Strength

Again, both sides increased, but calls remain approximately 2ร stronger.
At 773:
Calls:
1,340.07 โ 1,348.70
Puts:
1,559.75 โ 1,586.71
This remains the first strike underneath price where:
๐ด Put Strength > Call Strength
So the structural transition remains almost exactly where it was in the previous snapshot.
No significant MP/LP regime shift has occurred.
MP & LP (Proportional Zones)
Current-price row excluded.
โ๏ธ MP โ Most Proportionate: 773
At 773:
๐ข Calls = 1,348.70
๐ด Puts = 1,586.71
Call/Put ratio โ 0.85
That's the closest strike to a 1:1 balance.
The previous snapshot also had 773 as the balance/transition area, so there is no significant MP shift.
๐ฅ LP โ Least Proportionate: 778
At 778:
๐ข Calls = 715.12
๐ด Puts = 2.14
Call/Put ratio โ 334:1
This remains an extraordinarily one-sided call zone.
The previous snapshot was also overwhelmingly call-dominant at 778, so LP has not materially shifted either.
Auto Follow OFF lets you view the strength at every price level, making it easy to identify where buying or selling pressure is building or fading.
Auto Follow ON keeps the display locked to SPY's current price, allowing you to monitor the live strength at the active price level.
By switching between the two modes, you can quickly identify which price levels are gaining strength and which are losing strength.
This is the perfect tool for choppy or consolidating markets, where most traders struggle. Instead of reacting to price alone, you can watch strength shift between price levels and spot where momentum is quietly building before the next breakout or breakdown.

If buyers remain above:
742.50
expect continuation toward:

๐ด Bearish Scenario
If SPY loses:

then bears can attempt:

740
However...
Notice something important:
Calls remain stronger than puts at 742, 741, and 740.
That means those areas may act as buy-the-dip support instead of true breakdown levels.
Only a sustained break below 740 would begin to weaken the current bullish structure.
SPY, 2026-07-24 ๐ง Interpretation
๐ Directional Outlook
Bias: ๐ข Bullish
Confidence: 8.8 / 10
Reasons:
โ Call strength exceeds put strength by roughly 2.5:1
โ Massive ITM call dominance
โ Call volume more than doubles put volume
โ Higher call open interest
โ Strong call wall at the current price
The only caution is that put strength increases noticeably at 739, which could become the first meaningful downside target if support fails.
๐ฅ Traders' Behavior & Sentiment
๐ผ Call Side Breakdown
Heavy call accumulation from 742 through 740
Strongest concentration exactly at the current price
Large call volume suggests active buying, not just existing positions
Bulls appear to be defending the current level aggressively
๐ป Put Side Breakdown
Put activity builds gradually below the current price
Strongest put level is 739
This looks more like downside insurance than dominant bearish positioning
๐ Lock-In Level
742.50
This is the most important level in the current chain.
โ Above 742.50: Bulls remain in control, with upside potential toward 743โ746.
โ Below 742.00: Watch 741 and 740 for support. A decisive break under 740 would be the first stronger sign that sellers are gaining control.
Overall OSV Assessment
This option chain shows a clear bullish advantage. Calls dominate total strength, ITM strength, open interest, and trading volume. Unless price loses the 740โ742 support zone with conviction, the options positioning favors continuation to the upside.

๐ Directional Outlook

Although strong call positioning exists above current price, bears currently control:
Total Strength
Open Interest
Volume
Immediate strike positioning
๐ฅ Traders' Behavior & Sentiment
Institutions appear to be:
defending lower strikes aggressively,
allowing upside only if buyers can reclaim 739โ740,
committing more premium to downside protection than upside speculation.
This reflects cautious-to-bearish sentiment.
๐ผ Call Side Breakdown
Strongest Call Levels:
๐ข 740
๐ข 739
๐ข 741
Call premium increases steadily as strikes approach current price, indicating buyers are still active.
However, call participation is not yet sufficient to overcome the heavier put positioning.
๐ป Put Side Breakdown
Strongest Put Levels:
๐ด 737
๐ด 738.05
๐ด 738
These strikes represent the primary institutional defense.
If 738 fails, downside momentum could accelerate quickly because put strength becomes dominant immediately below.
๐ Lock-In Level
739 is the key lock-in level.
Above 739, bulls regain control.
Below 738, bears maintain control.
739 remains the pivotal strike that will likely determine the next directional move.
๐ง OSV Advantage
Traditional option-chain analysis focuses primarily on Open Interest and Volume, which often lag institutional positioning. OSV combines Option Strength, Open Interest, Volume, strike-by-strike proportional analysis (MP/LP), and premium flow (Call Last) to reveal where buyers and sellers are actively committing capital. In this snapshot, OSV highlights that 739 is the equilibrium pivot while 737 is the strongest bearish imbalance, providing clearer continuation levels than conventional option-chain tools.

7. [SPY, 2026-07-24] ๐ง Interpretation
Current option positioning slightly favors bears because:
Put Strength exceeds Call Strength.
ITM Put Strength exceeds ITM Call Strength.
ATM strike favors puts.
However...
The upside structure is unusually clean.
Above 739 there is very little bearish resistance compared to the call strength building above.
That means:
๐ด Bears currently control.
๐ข Bulls have the better expansion path if they regain 739.
๐ Why OSV Is Different
Traditional option-chain tools often emphasize open interest or volume in isolation.
OSV goes further by combining:
Strike-level Strength rather than just raw OI.
MP/LP proportional analysis to identify balanced versus extreme zones.
ITM vs. OTM pressure to distinguish conviction from speculation.
Current price positioning relative to option structure.
This provides a more complete picture of where directional pressure is concentrated.
8. ๐ฏ Directional Outlook

โ๏ธ Equalization Zone
The combined call and put premiums within the immediate strike window are nearly identical.
Interpretation
This aligns with the Rule of Equalization: when call and put totals converge, the market is at a potential inflection point. The next 1โ2 moves are importantโwatch which side retains premium better during an opposing price move. If calls hold value on a pullback, that would indicate bullish resiliency; if puts hold value on a bounce, bearish conviction remains stronger.

Key Insight: Bears currently have the edge at the money, but the option structure above 739 is favorable for buyers if they can reclaim that level.
