# Heart Attack Ping Pong (Bid-Ask-Flip)
Best for deep price corrections and retracment in early & high volume-token launches
## What is Heart Attack Ping Pong (Bid-Ask-Flip)
Heart Attack Ping Pong (Bid-Ask-Flip) is a HawkFi model variation of the HawkFi [Heart Attack](/whitepaper/hawkfi-solana/hawkfi-models/heart-attack.md) model. It uses the same Heart Attack correction and retracement logic, but adds automations to flip liquidity once conditions are met.

## Model Overview
| Model | LP Details |
| ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Best for | Deep correction and retracement setups in early and high-volume token launches, where the position may need to move lower before the bounce setup plays out. |
| How it works | Compared with the parent Heart Attack model, this variation uses Bid-Ask liquidity plus down-only Ping Pong AR with a 69-0-69 range setup.
The variant keeps the Heart Attack focus on launch correction entries, but adds range movement lower, TP:SOL for profit exits, and SL:SOL for pool price dip protection.
|
| Ideal entry | During deep launch corrections with expected retracement: wide, single-side SOL only |
## What changes from Heart Attack?
| What stays the same | What changes in Heart Attack Ping Pong |
| ---------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| Still belongs to the Heart Attack model family for early, high-volume token launch corrections and retracements. | Adds down-only Ping Pong AR so the working range can reset lower when the correction continues. |
| Still uses SOL-denominated exits as the clean model outcome. | Adds both TP:SOL and SL:SOL, so the variant has a profit-taking exit and a pool price dip protection exit. |
| Still targets correction entries where single-side SOL can be deployed into a launch pullback. | Uses Bid-Ask liquidity with a 69-0-69 Ping Pong setup, making it more directional and more defensive than the simpler Heart Attack variants. |
## Model Building Blocks
While this is a model variation with a combination of automations, the automations are still customizable to your liking.
| Model components | Why it is included | Default Settings |
| ----------------------- | -------------------------------------------------------------------------------------------------- | ----------------------------------------------- |
| Bid-Ask liquidity shape | Places directional liquidity for deeper correction and retracement setups. | Bid-Ask |
| Auto-rebalance (AR) | Lets the variant keep following downside continuation instead of staying fixed at the first range. | Down Only, 0 minute cooldown, Ping Pong 69-0-69 |
| Take Profit (TP) | Closes the position into SOL when the configured profit condition is reached. | TP:SOL, 7% profit, customizable |
| Stop Loss (SL) | Closes the position into SOL if the configured pool price dip condition is reached. | SL:SOL for pool price dip protection |

## Why choose Heart Attack Ping Pong (Bid-Ask-Flip)?
Heart Attack Ping Pong is for launch conditions where the correction may be too deep or too fast for the simpler Heart Attack versions.
The simple tradeoff is:
* Heart Attack Tight keeps the setup simpler and tighter for shallow corrections.
* Heart Attack Wide adds wider Bid-Ask coverage for deeper corrections.
* Heart Attack Ping Pong adds down-only Ping Pong AR plus SL:SOL when the setup needs the range to keep moving lower and still preserve SOL-denominated exits.
