Get the data
For the stock market, those stocks with relatively large gains and declines are mostly hot money gathering places, and these gathering places often have a very high probability of being on the top of the list. For retail investors who like to play short-term, especially investors who like to fight through the list, especially love the Dragon and Tiger List. Therefore, we can provide such a list for our trading software.
The way to get the free Dragon and Tiger List is as follows:
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")
The first parameter is the date, and the second parameter is the type of dragon and tiger list obtained. Here, our dates are set manually. When we arrive later, we can replace them by judging the working days.
pyqt5 displays the data of the dragon and tiger list
First of all, we need to get the data of the Dragon and Tiger List through threads, the specific code is as follows:
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)
After the data acquisition is completed, it can be directly displayed on the interface. The code of main.py is as follows:
class MyFrom(QMainWindow):
# 龙虎榜

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

Here, in order to be lazy, the blogger did not use the for loop to generate pyqt5 controls. Those who are interested can imitate Chapter 11 of Quantitative Trading and use the for loop to generate QLabel to generate QTableWidgetItem.
After running, the displayed effect is as shown in the figure below:
