我正在尝试从文本文件中提取一个变量来在交易机器人算法中进行数学运算。
这是我的代码。我已缩短它以解决问题：
from botlog import BotLog
from botindicators import BotIndicators
from bottrade import BotTrade
class BotStrategy(object):
def __init__(self):
self.output = BotLog()
self.prices = []
self.closes = [] # Needed for Momentum Indicator
self.trades = [] #20 trades at 0.021 = .042
self.currentPrice = "" #after a day, add the BTC to 0.042 and adjust simultaneous trades
self.currentClose = "" #53 coins for 2500 simul trades per coin pair
self.numSimulTrades = 100 #looks like dash ends at 2500 trades eth ends at about 1000 trades total for all four would be about 208 coins
self.indicators = BotIndicators()
mid=0
with open('test.txt', 'r') as myfile:
mid=myfile.read().replace('\n', '')
self.output.log(mid)
mid=int(mid)
def tick(self,candlestick):
self.currentPrice = float(candlestick.priceAverage)
self.prices.append(self.currentPrice)
#self.currentClose = float(candlestick['close'])
#self.closes.append(self.currentClose)
self.output.log("Price: "+str(candlestick.priceAverage)+"\tMoving Average: "+str(self.indicators.movingAverage(self.prices,5)))
self.evaluatePositions()
self.updateOpenTrades()
self.showPositions()
def evaluatePositions(self):
openTrades = []
for trade in self.trades:
if (trade.status == "OPEN"):
openTrades.append(trade)
if (len(openTrades) < self.numSimulTrades):
if ((self.currentPrice) < self.indicators.movingAverage(self.prices,15)):
self.trades.append(BotTrade(self.currentPrice,stopLoss=.0001))
for trade in openTrades:
if ((self.currentPrice + mid) > self.indicators.movingAverage(self.prices,15)) :
trade.close(self.currentPrice)
def updateOpenTrades(self):
for trade in self.trades:
if (trade.status == "OPEN"):
trade.tick(self.currentPrice)
def showPositions(self):
for trade in self.trades:
trade.showTrade()
使用“self.mid”我收到错误：'Bot1'对象没有属性'mid' 如果我删除了“self”，我得到：NameError：全局名称'mid'未定义
我做错了什么？我正在失去理智！
请求回溯：这是无属性：

现在全面展示。任何帮助将不胜感激。
答案 0 :(得分：0)
运行时系统是正确的。在mid案例中，mid中没有定义变量evaluatePositions。同样，mid的实例没有对象属性BotStrategy。看一下初始化的区别：
class BotStrategy(object):
def __init__(self):
self.output = BotLog()
self.prices = []
self.closes = [] # Needed for Momentum Indicator
...
mid=int(mid)
mid是 init 的局部变量，而不是属性。也许你需要
self.mid = int(mid)
并在您引用该值时使用self.mid。
这对你有用吗？
