+This oracle can be used in the same way as the crypto exchange rates oracle, the only difference being the oracle address and ticker of the pair. Each oracle also shows moving averages over the previous ten units, GBYTE_USD_MA and GBYTE_BTC_MA for the exchange rates and GBYTE_XAU_MA and GBYTE_XAG_MA for the precious metals.

 ==Using the crypto-exchange-rates oracle in a smart contract==
 # Practise thoroughly with small amounts of money first. The finished contract is human-readable but it is not obvious to a novice who gets to pay what under what conditions.
 # Pair up with a peer in wallet chat. Agree on the terms for the contract with your peer as needed throughout. After you have started writing the contract you will not be able to use the wallet chat until you finish (or abort) it. So either carefully agree all the details first, or have a separate chat channel open.
