# FUTURE Auto-Liquidity Engine (CALE)

**Market Liquidity is an important element that plays a vital role in allowing the buy & sell of $FUTR tokens on PancakeSwap.**

In simple terms, think of Liquidity as a big pool of money that is split into half (50/50) between **$FUTR** tokens & $BNB tokens. There is a conversion ratio is set that determinesto the amount of **$FUTR** you can get with BNB, for example: 1 BNB = 18.1 **FUTURE**.

When someone buys **FUTURE**, the price per **FUTURE** appreciates and the ratio above will also change accordingly to account for this. The same is applicable in the opposite direction for sells.

Liquidity allows everyone to buy & sell their **FUTURE**/**BNB** at anytime, however, if there is a liquidity constraint in the pool, you might get bad prices. To counter this, what our **FUTURE** Auto-Liquidity Engine (SALE) does is, to add more liquidity to that pool by itself and eventually solving that issue.

<mark style="color:green;">**Here is how the FUTURE Auto-Liquidity Engine (CALE) works:**</mark>

After every 24 hours our **FUTURE** Auto-Liquidity Engine (CALE) will inject automatic liquidity into the market. On each buy or sell order there is a **2.5% tax fee** that will automatically gets stored into an Auto-LP wallet and built into our protocol's smart contract, the is the mechanism which smartly takes the 50% of the amount of **FUTURE** stored in the wallet, and will **automatically** buy BNB at the current market price.

The remaining 50% of **FUTURE** in the Auto-LP wallet will be used for the **FUTURE** side of liquidity, therefore giving equal an 50/50 weighting of **FUTURE**/**BNB** which will then be **automatically** added as new, additional liquidity into the market pair and raising the amount of liquidity in the pool.

The CALE will do this **every 24 hours;** by constantly adding liquidity to the pool which will, in turn, allow **$FUTURE** token holders to sell their tokens easily, at anytime with minimum to no market slippage. It will also aid in **maintaining protocol stability** to make sure the APY is sustained for the entire life of **FUTURE**.
