+#### Get data for non-tradeable pairs
+
+Data for additional pairs (reference pairs) can be beneficial for some strategies.
+Ohlcv data for these pairs will be downloaded as part of the regular whitelist refresh process and is available via `DataProvider` just as other pairs (see above).
+These parts will **not** be traded unless they are also specified in the pair whitelist, or have been selected by Dynamic Whitelisting.
+
+The pairs need to be specified as tuples in the format `("pair", "interval")`, with pair as the first and time interval as the second argument.
+
+Sample:
+
+``` python
+def additional_pairs(self):
+    return [("ETH/USDT", "5m"),
+            ("BTC/TUSD", "15m"),
+            ]
+```
+
+!!! Warning:
+    As these pairs will be refreshed as part of the regular whitelist refresh, it's best to keep this list short.
+    All intervals and all pairs can be specified as long as they are available (and active) on the used exchange.
+    It is however better to use resampling to longer time-intervals when possible
+    to avoid hammering the exchange with too many requests and risk beeing blocked.
+
 ### Additional data - Wallets
 
 The strategy provides access to the `Wallets` object. This contains the current balances on the exchange.
