To launch oracle app first open a configuration:

nano ~/.oracle-app/config.yaml

And put next lines to end of file to enable oracles for btc_usdt, eth_usdt (binance) pairs, and simulation of dfi_eth and dfi_btc prices:

exchanges:
  - binance:
      - code: eth_usdt
        pair:
          base: ETH
          quote: USDT
      - code: btc_usdt
        pair:
          base: BTC
          quote: USDT
  - dfinance-test:
      - code: dfi_eth
        pair:
          base: dfi
          quote: eth
        simulate:
          enabled: true
          min_price: 869000
          max_price: 871000
          period_s: 1
      - code: dfi_btc
        pair:
          base: dfi
          quote: btc
        simulate:
          enabled: true
          min_price: 18000
          max_price: 20000
          period_s: 1

Save file. Now it's possible to launch:

DN_ORACLEAPP_MNEMONIC="<mnemonic>" oracle-app start

Where <mnemonic> must be replaced with your mnemonic from account with oracle status. The rest of parameters:

* DN_ORACLEAPP_ACCOUNT - number of account in standard hd path ((44'/118'/{account}'/0/{index}).
* DN_ORACLEAPP_INDEX - number of index of account in standard hd path ((44'/118'/{account}'/0/{index}).
