Heatseeker Product Overview
What is Heatseeker?
Heatseeker is a powerful visual tool that simplifies how traders understand the invisible forces that drive price action in the market. It gives you real-time actionable insights into how the largest and most influential players in the market, like dealers and institutions are positioned, so you can make smarter decisions with more confidence.
Why Heatseeker Matters
Markets don’t move randomly. Every tick up or down is influenced by complex dynamics behind the scenes. Heatseeker distills those dynamics into a clean and intuitive interface, helping you:- Predict price direction with greater accuracy
- Know whether the market is likely to chop, range, or trend
- Align with or trade against market dealer positioning
- Sell and manage stocks, options, and futures more effectively
Understanding the Market Participants
To make sense of what Heatseeker is showing you, it’s helpful to understand the main players in the options market.Market Dealers
These are the liquidity providers. Think of them like casino operators. Their job is to take the opposite side of a trader’s position, hedge their risk, and profit off spreads and volatility. Because they are always hedging, their positioning creates pressure in the market that can influence price movement.Institutions & Funds
These are large entities like mutual funds, pension funds, and hedge funds. They make big, strategic bets and often have long time horizons. Their options activity tends to be deliberate and can anchor key levels in the market.Customers
This includes both retail traders and smaller professional traders. Their flow can be unpredictable, but when large numbers of customers buy the same contracts, it creates stress in the system that dealers need to hedge against.How Heatseeker Works
Heatseeker monitors ingests and processes real-time data and identifies where dealers are accumulating risk. It maps out these zones using a color gradient: Bright Yellow (Pika) Nodes represent price areas where dealers are positioned in a way that absorbs price movement. These areas tend to reduce volatility. Think of yellow as a “magnetic pillow” — price often slows down or gets pinned here. These levels can also often be used and seen as reversal zones.


How to Use Heatseeker
Scenario: Trending Day
If price is moving smoothly toward a major node with no other strong node in the opposing direction, be prepared for an expansion in volatility. These are moments where momentum trading works best.Scenario: Choppy or Range-Bound Day
If price is trapped within yellow zones, expect low volatility and lots of fake outs. This is ideal for premium-selling strategies or reversal strategies, such as fading the edges of the range.Scenario: High Volatility Interactions
Watch for price approaching purple zones with speed. Once inside, expect fast moves. Traders can position themselves to ride the volatility burst or manage risk more proactively.E.G. if there is a major purple node below current price, you can expect a potentially aggressive bounce there.
