# fCash Markets

## Get active fCash Markets

We can use the `getActiveMarkets` method to get a list of the current active markets in a given currency:

```
 activeMarkets = notional.getActiveMarkets(currencyId)
```

## Get a market's total fCash and total Prime Cash holdings

```
market3Months = activeMarkets[0]
market6Months = activeMarkets[1]

# Get the maturity of the 3 Month market
maturity = market3Months[1]

# Get the 3 Month market total Prime Cash balance 
primeCashBalance3MonthMarket = market3Months[3]/1e8

# Get the 3 Month market total fCash balance
fCashBalance3MonthMarket  = market3Months[2]/1e8
```

## Get a market's utilization

An fCash market's utilization is defined as total `fCash/ (total fCash + total Prime Cash in underlying)`: 

<pre><code>from brownie.network.state import Chain
chain = Chain()

primeFactors = notional.getPrimeFactorsStored(currencyId, chain.time())
supplyScalar = primeFactors["factors"]["supplyScalar"]/1e18
underlyingScalar = primeFactors["factors"]["underlyingScalar"]/1e18

<strong>marketPrimeCashSupply = primeCashBalance3MonthMarket * underlyingScalar * supplyScalar
</strong><strong>fCashMarketUtilization =  fCashBalance3MonthMarket / (fCashBalance3MonthMarket + marketPrimeCashSupply) 
</strong><strong>
</strong></code></pre>

## Get fCash rates

```
# Last Implied Rate 3 Month Market
lastImpliedRate = market3Months[5] 

# Oracle Rate 3 Month Market
oracleRate = market3Months[6]
```
