-- `targetCurrencies`
+- `baseCurrencies`
     - A list of currencies you want to hold in your portfolio.
 - `threshold`
     - The threshold of the difference between the current weight and the target weight to trigger rebalancing. For example, if the threshold is `1%` and the current weight of `BTC` is `52%` and the target weight is `50%` then the strategy will sell `BTC` until it reaches `50%`.
 - `dryRun`
     - If `true`, then the strategy will not place orders.
 - `maxAmount` 
-    - The maximum amount of each order in base currency.
+    - The maximum amount of each order in quote currency.
