对于股市来说,那些涨幅跌幅都比较大的股票多是游资的聚集地,这些聚集地往往登上龙虎榜的几率非常的高。对于喜欢玩短期的散户来说,尤其喜欢通过该榜单搏一搏的投资者,尤其钟爱龙虎榜。所以,我们可以给我们的交易软件提供一个这样的榜单。
获取免费龙虎榜的方式如下:
df_rise = ak.stock_sina_lhb_detail_daily(trade_date="20210205", symbol="涨幅偏离值达7%的证券")
df_fall = ak.stock_sina_lhb_detail_daily(trade_date="20210205", symbol="跌幅偏离值达7%的证券")
第1个参数如日期,第2个参数为获取的龙虎榜类型。这里,我们的日期都是手动设置的,等我们到后面,通过判断工作日,将其替换掉就行。
首先,我们需要通过线程获取到龙虎榜的数据,具体代码如下:
import akshare as ak
from PyQt5 import QtCore
from PyQt5.QtCore import pyqtSignal
from pandas import DataFrame
class OtherThread(QtCore.QThread):
_signalRise = pyqtSignal(DataFrame)
_signalFall = pyqtSignal(DataFrame)
def __init__(self):
super(OtherThread, self).__init__()
def run(self):
df_rise = ak.stock_sina_lhb_detail_daily(trade_date="20210205", symbol="涨幅偏离值达7%的证券")
df_fall = ak.stock_sina_lhb_detail_daily(trade_date="20210205", symbol="跌幅偏离值达7%的证券")
self._signalRise.emit(df_rise)
self._signalFall.emit(df_fall)
数据获取完成之后,就可以直接显示到界面上了,main.py的代码如下所示:
class MyFrom(QMainWindow):
# 龙虎榜

self.otherGrid = QGridLayout()
self.otherGrid.setSpacing(5)

这里,博主为了偷懒,没有使用for循环生成pyqt5的控件。感兴趣的可以模仿量化交易第11篇,使用for循环生成QLabel的方式生成QTableWidgetItem。
