For example, if you have 10 ETH available in your wallet on the exchange and `tradable_balance_ratio=0.5` (which is 50%), then the bot will use a maximum amount of 5 ETH for trading and considers this as available balance. The rest of the wallet is untouched by the trades.
!!! Danger
This setting should **not** be used when running multiple bots on the same exchange. Please look at [Available Capital to the bot](#assign-available-capital) instead.
!!! Warning
The `tradable_balance_ratio` setting applies to the current balance (free balance + tied up in trades). Therefore, assuming the starting balance of 1000, a configuration with `tradable_balance_ratio=0.99` will not guarantee that 10 currency units will always remain available on the exchange. For example, the free amount may reduce to 5 units if the total balance is reduced to 500 (either by a losing streak, or by withdrawing balance).
#### Assign available Capital
To fully utilize compounding profits when using multiple bots on the same exchange account, you'll want to limit each bot to a certain starting balance.
This can be accomplished by setting `available_capital` to the desired starting balance.
Assuming your account has 10.000 USDT and you want to run 2 different strategies on this exchange.
You'd set `available_capital=5000` - granting each bot an initial capital of 5000 USDT.
The bot will then split this starting balance equally into `max_open_trades` buckets.
Profitable trades will result in increased stake-sizes for this bot - without affecting stake-sizes of the other bot.
!!! Warning "Incompatible with `tradable_balance_ratio`"
Setting this option will replace any configuration of `tradable_balance_ratio`.
#### Amend last stake amount
Assuming we have the tradable balance of 1000 USDT, `stake_amount=400`, and `max_open_trades=3`.
