我正在努力从交易API中获取当前买卖价格，将其与我购买的职位进行比较，然后采取适当的措施 - 出售或购买
由于交易费用而有出售和购买价格
有5个组件：
- 开始购买股票的价格
- 股票的当前买价
- 目前的股票卖出
- 上一买价（我买了股票）
- 以前的卖价（我在哪里出售股票）
我需要看看第一个价格变化是什么相对于我的起始位置，如果我可以买到较低，然后购买；如果我可以出售更多，请出售。但是我想重复很多次。
因此，如果我买了更多，请设置上一买价，然后如果当前的卖出价格上涨，那就出售。然后在购买方面相同
这是我需要帮助的逻辑：
： Start_buy_price = 100
Start scenario 1:
# buy price from start price drops to 90
buy_price = 90:
buy_price < start_buy_price:
buy!
set previous_buy_price = buy_price
# price to sell then rises to 95
sell_price = 95
sell_price > previous_buy_price:
Sell!
set previous_sell_price = sell_price
Start scenario 2:
# price to sell rises to 105
sell_price = 105
sell_price > start_buy_price:
Sell!
set previous_sell_price = sell_price
# price to buy then falls to 100
buy_price = 100
buy_price < previous_sell_price:
Buy!
set previous_buy_price = buy_price
----------------------------------------------------------------------
Following run through of the code:
Following scenario 1:
# price to buy is lower than previous sell price
buy_price < previous_sell_price:
Buy!
set previous_buy_price = buy_price
# price to sell is higher than previous buy price
sell_price < previous_buy_price:
Sell!
set previous_sell_price = sell_price
repeat!
我已经盯着这个问题了大约3个小时，试图在Python做到这一点。到目前为止，这是我的代码：
def run_this_code():
start_buy_price = 100 # enter what I bought in at
get_buy_price = client.get_buy_price(buy_price)
get_sell_price = client.get_sell_price(sell_price)
buy_price = float(get_buy_price['amount'])
sell_price = float(get_sell_price['amount'])
if buy_price < start_buy_price:
action = 'Buy!'
previous_buy_price = buy_price
if sell_price > start_buy_price:
action = 'Sell!'
previous_sell_price = sell_price
if previous_buy_price !=None:
if sell_price > previous_buy_price:
action = 'Sell!'
previous_sell_price = sell_price
if previous_sell_price !=None:
if buy_price < previous_sell_price:
action = 'Buy!'
previous_buy_price = buy_price
print(action,'start_buy:', start_buy_price,'buy:', buy_price,'sell:', sell_price)
pass
run_this_code()
我真的在这里挣扎，请有人可以帮助我将我的if我的if我的if转换为第一个缩进的文本块中的python代码，该代码可以多次运行
这四行是奇怪的：
get_buy_price = client.get_buy_price(buy_price)
get_sell_price = client.get_sell_price(sell_price)
buy_price = float(get_buy_price['amount'])
sell_price = float(get_sell_price['amount'])
您的前两个呼叫功能，但是参数似乎在任何地方都没有定义。您的第二个依赖于对前两个呼叫的响应都是字典，这在没有存在的论点的情况下很难。
您可能还想研究"循环"/"，因为这些会有助于"很多次"。
我得到了它！
这是您给它以100英镑的价格购买的价格。然后，我将API称为寻找卖价。如果售价低于100英镑，请卖出并将以前的卖价设定为此。如果购买价格将属于以前的购买价格，请购买。然后移至下一个循环，仅在获得折扣或利润时仅执行买卖，并且只有在连续重复同一措施
