Most retail stops sit clustered just beneath the most obvious support line on a price chart. Large operators view those exact clusters as liquidity pools, driving price through the floor to fill their buy orders before the real markup starts. This maneuver is known in the Wyckoff methodology as a Spring or a Terminal Shakeout. It is the defining event of Phase C, designed to test the remaining supply and trap late sellers.
The Anatomy of a Spring
To understand why springs happen, you must observe the market through the lens of the Composite Operator, the institutional force behind major trends. Large institutions cannot buy millions of shares without pushing the price against their own execution. To build a significant position, they require counterparties.
An obvious support line acts as a magnet. It represents where retail traders place protective stop-loss orders and where momentum traders set breakout-sell triggers. By allowing the price to slip below support, large operators trigger these sell orders. This creates a temporary surge of sell-side liquidity, allowing institutions to buy heavily without driving the market up.
The Three Types of Springs
Richard Wyckoff's successor, Robert Evans, classified these events into three distinct types based on the volume and price spread at the break.
Spring Type 1 (The Terminal Shakeout)
This is a violent, deep break of support on massive volume and wide price spreads. It represents a heavy flush of supply. Because the supply is strong, this shakeout requires a dramatic, immediate surge in buying interest to recover. If the price fails to regain the range quickly, the structural breakdown is real and a new base must form.
Spring Type 2 (The Moderate Test)
Here, the price breaks support with moderate volume and some expansion in price spread. Floating supply is present but manageable. Before the price can mark up, operators must absorb this supply. Traders should expect successive retests of this low to confirm sellers are completely exhausted.
Spring Type 3 (The Exhaustion Spring)
This is the highest-conviction setup. The price slips below support on narrow price spreads and very low volume. This signature proves that downside selling pressure is completely dry. No one is willing to sell at these prices, indicating the float is locked and the path of least resistance is up.
How to Trade the Shake
Rushing to buy the exact moment support breaks is a common trading error. Wyckoff practitioners look for confirmation before committing capital.
The golden rule is the Spring Test. For Type 1 and Type 2 springs, wait for a secondary reaction back into the breakout zone. This test should print a higher low on significantly lower volume, confirming that sellers have finished their business.
When you observe a successful Test of a Spring Type 3, or a successful retest of a Type 2, it establishes a tight, asymmetric risk-reward boundary. Your invalidation level sits just below the swing low of the spring, giving you a clear floor to manage risk while targeting the top of the trading range.
