# High Frequency Liquidity (HFL) Tight
Aggressive HFL with boosted fee-generation from tighter ranges and 0-min swapless auto-rebalances
## What is HFL Tight
High Frequency Liquidity (HFL) Tight is a HawkFi model variation of [High Frequency Liquidity (HFL)](/whitepaper/hawkfi-solana/hawkfi-models/high-frequency-liquidity-hfl.md). It uses the same HFL behavior, but changes the Ping Pong range to `6-0-6` for tighter fee concentration and faster range-following.

## Model Overview
| Model | LP Details |
| ------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Best for | High-volume pools where the LP wants the most aggressive HFL range concentration instead of the base HFL Regular setup or the wider HFL Wide setup. |
| How it works |
HFL Tight keeps the parent HFL setup of SPOT liquidity, AA:SOL, AR UP & DOWN, 0-minute swapless Ping Pong Auto-rebalance, and SL:SOL @ -20% POOL PRICE.
The variation changes the Ping Pong range to 6-0-6, making it the tightest HFL model range for more aggressive fee concentration near the active bin (pool price).

| Ideal entry |
- During active sideways price action where tight fee concentration can stay useful - When the LP wants HFL behavior with the tightest model Ping Pong range - When more aggressive range-following matters more than broader range coverage

## What changes from High Frequency Liquidity (HFL)?
| What stays the same | What changes in Tight |
| ------------------------------------------------- | ---------------------------------------------------------- |
| Same parent model: High Frequency Liquidity (HFL) | Starting range width changes to `8 BINS` |
| Same liquidity shape: SPOT | Ping Pong range changes to `6-0-6` |
| Same included automations: AA, AR, and SL | Built for LPs who want the most aggressive HFL model range |
## Strategy Building Blocks
While this is a model variation with a combination of automations, the automations are still customizable to your liking.
| Model Components | 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 6-0-6 |
| Stop Loss (SL) | Adds the model downside exit condition. | SL:SOL @ -20% POOL PRICE |
| (More Customizations Available) | After deploying a model, you can further customize your position automations based on market conditions and personal preferences. | Customizable |

## Why choose HFL Tight?
HFL Tight is for LPs who want the same parent HFL behavior, but with the tightest model Ping Pong range.
The simple tradeoff is:
* HFL Regular uses `12-0-12` as the base setup.
* HFL Tight changes the range to `6-0-6` for more aggressive fee concentration.
* You choose Tight when you still want HFL behavior, but want less range width than the standard HFL Regular setup.
