我试图下限后限价单，这样就不会产生费用，以下是相关声明：
from coinbase.wallet.client import Client
spot_price = client.get_spot_price(currency_pair = 'BTC-USD')
priceStr = repr(float(spot_price.amount) - 25.0)
buy_order = primary_account.buy(amount = '0.001', currency = 'BTC', price = priceStr, post_only = True )
print("buy_order=", buy_order, "price=", priceStr)
However, it did not work as a fee of 0.99 is charged and also the price is higher.
What could be wrong?
好的，现在我意识到问题可能是我使用的是Coinbase API密钥，而不是Coinbase.Pro（以前是GDAX）API密钥。我已经生成了Pro API密钥，并将在明天重试（因为更改似乎将在明天进行）。感谢所有尝试提供帮助的人。
谢谢， 肖恩
