Assuming we have the tradable balance of 1000 USDT, `stake_amount=400`, and `max_open_trades=3` (This example assumes `tradable_balance_ratio=1`).
Assuming we have the tradable balance of 1000 USDT, `stake_amount=400`, and `max_open_trades=3`.
The bot would open 2 trades, and will be unable to fill the last trading slot, since the requested 400 USDT are no longer available, since 800 USDT are already tied in other trades.
To overcome this, the option `amend_last_stake_amount` can be set to `True`, which will enable the bot to reduce stake_amount to the available balance in order to fill the last trade slot.

!!! Note
This option only applies with [Static stake amount](#static-stake-amount) - since [Dynamic stake amount](#dynamic-stake-amount) divides the balances evenly.
!!! Note
The minimum last stake amount can be configured using `amend_last_stake_amount` - which defaults to 0.5 (50%). This means that the minimum stake-amount that's ever used is `stake_amount * 0.5`. This avoids very low stake-amounts, close to the minimum tradable amount.
#### Static stake amount
The `stake_amount` configuration statically configures the amount of stake-currency your bot will use for each trade.
