High Frequency Liquidity (HFL) Regular is a HawkFi model for people who want highly concentrated fee generation from tight-range, fast 0-minute swapless auto-rebalances.

## Model Overview

| Model        | LP Details                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |

| Best for     | High-volume pools where concentrated fee generation matters and the LP wants the standard HFL setup before choosing a tighter or wider range variant.                                                                                                                                                                                                                                                                                                                                                                             |

## Model Building Blocks

While this is a model with a combination of automations, the automations are still customizable to your liking.

|                           | LP effect                                                                            | Default settings                          |
| ------------------------- | ------------------------------------------------------------------------------------ | ----------------------------------------- |
| Liquidity shape           | Keeps HFL focused on concentrated fee generation around the selected range.          | SPOT                                      |
| Auto-accumulate Fees (AA) | Accumulates earned fees to SOL instead of compounding them into the active position. | AA:SOL                                    |
| Auto-rebalance (AR)       | Moves the full LP range upward or downward as the HFL range is exited.               | UP & DOWN, 0M COOLDOWN, PING PONG 12-0-12 |
| Stop Loss (SL)            | Adds the model downside exit condition.                                              | SL:SOL @ -20% POOL PRICE                  |

## Why use HFL Regular?

HFL Regular is the base HFL configuration. It is the first HFL model to use when you want the standard tight-range, fee-focused setup before deciding whether the pool needs a tighter or wider Ping Pong range.

The simple range ladder is:

* HFL Regular uses `12-0-12` as the base setup.
* HFL Tight changes the range to `6-0-6` for more aggressive concentration.
* HFL Wide changes the range to `18-0-18` for more coverage.
