**One of the most important things is the market liquidity, which ensures the purchase and sale of $FP tokens on PacakeSwap.** 

In simple terms, liquidity is a certain amount of money that is divided into two equal parts between $FP tokens and $BNB tokens. There is also a conversion rate that corresponds to the amount of $FP you can receive from one BNB. For example, 1 $BNB = 100 $FP.

So, when someone buys $FP, the price of $FP tokens will rise and the ratio of $BNB to $FP will change. The same thing happens in the opposite direction when selling $FP tokens.

Liquidity allows anyone to buy and sell their $FP/BNB at any time, however, the less money/liquidity in the pool, the less money you can get, so the Finance Protocol Balance Auto-Liquidity Engine (BALE) automatically adds more liquidity to the pool thus solving this problem.

**Here is how the Finance Protocol Balance Auto-Liquidity Engine (BALE) works:**

Every 60 seconds, our BALE automatically adds liquidity to the market. Each buy or sell order **is subject to a 4% tax fee**, which is automatically stored in the Auto-LP wallet, and a mechanism built into the smart contract of our protocol that intelligently takes 50% of the amount of $FP held in the wallet automatically buys BNB at the current market price.  

The remaining 50% of the $FP in the Auto-LP wallet will be used for the $FP liquidity side, giving an equal weight of 50/50 FP/BNB, which will then be **automatically** added as new additional liquidity to the market of the pair and increase the amount of liquidity in the pool.

BALE will do this in **60 seconds**, adding more and more liquidity to the pool, allowing $FP token holders to easily sell their tokens at any time with little or no market slippage. This will also help **maintain protocol stability** to ensure that APY is maintained throughout the lifetime of $FP.
