Every quarter, billions of dollars in Bitcoin options expire and move the market in ways most traders never see coming. I got tired of being surprised, so I built something to watch it for me.
Today it flagged a signal I have never seen before: a 7.6% gap between Max Pain and spot price on the single largest expiry day of 2026. Here is exactly what that means and how the tracker works.
Why Options Expiry Matters More Than You Think
At 08:00 UTC today, $14.16 billion in Bitcoin options settle on Deribit. That is roughly 40% of total open interest being resolved in a single event. When this much notional value expires, the market does not just absorb it quietly.
Options market makers are hedged. As contracts approach expiry, they unwind those hedges. The direction of the unwind depends on where spot price sits relative to the strike distribution — specifically, relative to Max Pain.
Max Pain is the price at which the maximum number of options contracts expire worthless. Market makers benefit when price gravitates toward this level. Today, Max Pain is $75,000. Spot is $69,700.
That is a $5,300 gap. 7.6%.
The Architecture
Deribit API ──▶ Strike Aggregator ──▶ Max Pain Calculator
│ │
CoinGlass API ──▶ OI Snapshot ──▶ Gap Analyzer ──▶ Alert
│ │
Binance WS ──▶ Spot Price Feed ──▶ Funding Monitor
The tracker pulls three data streams:
- Deribit options chain — every active strike, put/call OI, and expiry date
- CoinGlass derivatives data — aggregate open interest, funding rates, liquidation levels
- Binance spot feed — real-time BTC price via WebSocket
Every 30 seconds, it recalculates Max Pain across all active expiry dates and compares it to spot. When the gap exceeds a configurable threshold (I use 5%), it fires an alert.
function calculateMaxPain(strikes) {
let minPain = Infinity;
let maxPainPrice = 0;
const allStrikes = strikes.map(s => s.strike);
for (const target of allStrikes) {
let totalPain = 0;
for (const s of strikes) {
// Call holders lose money below strike
const callPain = Math.max(0, target - s.strike) * s.callOI;
// Put holders lose money above strike
const putPain = Math.max(0, s.strike - target) * s.putOI;
totalPain += callPain + putPain;
}
if (totalPain < minPain) {
minPain = totalPain;
maxPainPrice = target;
}
}
return { maxPainPrice, totalPain: minPain };
}
Simple brute force over every strike. With ~200 active strikes on Deribit, this runs in under 1ms. No optimization needed.
What the Tracker Flagged Today
Here is what hit my dashboard this morning:
Max Pain: $75,000
Spot: $69,700
Gap: 7.6% — the largest I have recorded on any expiry day this year
Put/Call Ratio: 0.85 (calls dominate)
Total OI Expiring: $14.16B (40% of all Deribit OI)
Normally, price drifts toward Max Pain in the 48 hours before settlement. That magnetic effect is well-documented. But this time, geopolitics broke the pattern.
Iran rejected the U.S. ceasefire proposal overnight. Within hours, $193M in long positions were liquidated. BTC dropped from $71,300 to $69,700. The Max Pain magnet got overpowered by a war headline.
Combining Options Data with the Liquidation Map
The options expiry tracker becomes far more powerful when you overlay it with liquidation data. Here is the combined picture:
Long liquidation cluster: $67,000–$65,000. If price drops further, these longs get wiped, triggering cascading sells.
Short liquidation belt: $72,000–$75,000. If the Max Pain magnet kicks in post-settlement and pushes price up, these shorts get destroyed. We are talking $550M+ in potential cascading short liquidations. You can see the full real-time liquidation map at bitcoinkevin.com/en/bitcoin-liquidation-map-live/.
Tail risk zone: Below $61,000, there is $3B+ in queued long liquidations. Low probability, but catastrophic if triggered.
function assessExpiryRisk(maxPain, spot, liquidationClusters) {
const gap = (maxPain - spot) / spot;
const direction = gap > 0 ? 'upward' : 'downward';
const nearestCluster = liquidationClusters
.sort((a, b) => Math.abs(a.price - spot) - Math.abs(b.price - spot))[0];
return {
gapPercent: (gap * 100).toFixed(1),
direction,
nearestLiquidation: nearestCluster.price,
liquidationVolume: nearestCluster.volume,
riskLevel: Math.abs(gap) > 0.05 ? 'HIGH' : Math.abs(gap) > 0.03 ? 'MEDIUM' : 'LOW'
};
}
The Sentiment Layer: Fear at 8 for 47 Days
Here is the part that made me sit up. The Fear & Greed Index has been at 8–10 for 47 consecutive days. That is the longest extreme fear streak since the FTX collapse. I track this live at bitcoinkevin.com/en/bitcoin-fear-and-greed-index/.
But during FTX, BTC was at $15,000. Today it is at $69,000. Same fear reading, 4.6x the price.
I added a divergence detector to the tracker that compares Fear & Greed trends against price trends. When fear stays extreme while price holds steady or rises, it flags a divergence. The current divergence score is the highest I have ever recorded.
What does this mean practically? The market is priced for a crash that has not happened. $14.16B in options expire today. After settlement clears, one side of the liquidation map gets destroyed.
What I Learned Building This
Options data is the most underused edge in crypto. Everyone watches candles and RSI — I built a 300-coin RSI heatmap that proves how lopsided the market is right now. Almost nobody watches the strike distribution and Max Pain heading into expiry. The data is free. Deribit publishes it openly.
Combining data sources creates nonlinear insight. Options data alone tells you where market makers want price. Liquidation data tells you where leveraged traders are vulnerable. Fear & Greed tells you what retail is doing emotionally. Any one of these is a flashlight. All three together are a floodlight.
The biggest moves happen when everyone is frozen. Fear at 8 means 92 out of 100 market participants are paralyzed. That is when the 8 who are not paralyzed make the most money.
The options expiry tracker, liquidation map, RSI heatmap, and Fear & Greed dashboard all run live at bitcoinkevin.com/en/todays-crypto-market-brief/. If you are building anything with derivatives data, the Max Pain calculation and multi-source aggregation patterns here apply to any options market, not just crypto.
