I am trying to backtest a strategy where trades are only opened during 8.30 to 16.00 using backtrader.
Using the below attempt my code is running but returning no trades so my clsoing balane is the same as the opening. If I remove this filter my code is running correctly and trades are opening and closing so it is definitely the issue. Can anyone please help?
I have tried adding the datetime column of the data to a data feed using the below code:
` def __init__(self):
# Keep a reference to the "close" line in the data[0] dataseries
self.dataclose = self.datas[0].close
self.datatime = mdates.num2date(self.datas[0].datetime)
self.datatsi = self.datas[0].tsi
self.datapsar = self.datas[0].psar
self.databbmiddle = self.datas[0].bbmiddle
self.datastlower = self.datas[0].stlower
self.datastupper = self.datas[0].stupper
# To keep track of pending orders
self.order = None`
I then used the following code to try filter by this date range:
# Check if we are in the market
if not self.position:
current_time = self.datatime[0].time()
if datetime.time(8, 30) < current_time < datetime.time(16, 0):
if self.datatsi < 0 and self.datastupper[0] > self.dataclose[0] and self.datastlower[1] < self.dataclose[1] and self.dataclose[0] < self.databbmiddle[0] and self.datapsar[0] > self.dataclose[0]:
self.log('SELL CREATE, %.2f' % self.dataclose[0])
# Keep track of the created order to avoid a 2nd order
os = self.sell_bracket(size=100,price=sp1, stopprice=sp2, limitprice=sp3)
self.orefs = [o.ref for o in os]
else:
o1 = self.buy(exectype=bt.Order.Limit,price=bp1,transmit=False)
print('{}: Oref {} / Buy at {}'.format(self.datetime.date(), o1.ref, bp1))
o2 = self.sell(exectype=bt.Order.Stop,price=bp2,parent=o1,transmit=False)
print('{}: Oref {} / Sell Stop at {}'.format(self.datetime.date(), o2.ref, bp2))
o3 = self.sell(exectype=bt.Order.Limit,price=bp3,parent=o1,transmit=True)
print('{}: Oref {} / Sell Limit at {}'.format(self.datetime.date(), o3.ref, bp3))
self.orefs = [o1.ref, o2.ref, o3.ref] # self.sell(size=100, exectype=bt.Order.Limit, price=self.data.close[0]+16, parent=self.order, parent_bracket=bt.Order.Market)

you need to use .call() every time to refresh the balance!

I am building a vaccination appointment program that automatically assigns a slot to the user.
This builds the table and saves it into a CSV file:
import pandas
start_date = '1/1/2022'
end_date = '31/12/2022'
list_of_date = pandas.date_range(start=start_date, end=end_date)
df = pandas.DataFrame(list_of_date)
df.columns = ['Date/Time']
df['8:00'] = 100
df['9:00'] = 100
df['10:00'] = 100
df['11:00'] = 100
df['12:00'] = 100
df['13:00'] = 100
df['14:00'] = 100
df['15:00'] = 100
df['16:00'] = 100
df['17:00'] = 100
df.to_csv(r'C:\Users\Ric\PycharmProjects\pythonProject\new.csv')
And this code randomly pick a date and an hour from that date in the CSV table we just created:
import pandas
import random
from random import randrange
#randrange randomly picks an index for date and time for the user
random_date = randrange(365)
random_hour = randrange(10)
list = ["8:00", "9:00", "10:00", "11:00", "12:00", "13:00", "14:00", "15:00", "16:00", "17:00"]
hour = random.choice(list)
df = pandas.read_csv('new.csv')
date=df.iloc[random_date][0]
# 1 is substracted from that cell as 1 slot will be assigned to the user
df.loc[random_date, hour] -= 1
df.to_csv(r'C:\Users\Ric\PycharmProjects\pythonProject\new.csv',index=False)
print(date)
print(hour)
I need help with making the program check if the random hour it chose on that date has vacant slots. I can manage the while loops that are needed if the number of vacant slots is 0. And no, I have not tried much because I have no clue of how to do this.
P.S. If you're going to try running the code, please remember to change the save and read location.
Here is how I would do it. I've also cleaned it up a bit.
import random
import pandas as pd
start_date, end_date = '1/1/2022', '31/12/2022'
hours = [f'{hour}:00' for hour in range(8, 18)]
df = pd.DataFrame(
data=pd.date_range(start_date, end_date),
columns=['Date/Time']
)
for hour in hours:
df[hour] = 100
# 1000 simulations
for _ in range(1000):
random_date, random_hour = random.randrange(365), random.choice(hours)
# Check if slot has vacant slot
if df.at[random_date, random_hour] > 0:
df.at[random_date, random_hour] -= 1
else:
# Pass here, but you can add whatever logic you want
# for instance you could give it the next free slot in the same day
pass
print(df.describe())
import pandas
import random
from random import randrange
# randrange randomly picks an index for date and time for the user
random_date = randrange(365)
# random_hour = randrange(10) #consider removing this line since it's not used
lista = [# consider avoid using Python preserved names
"8:00",
"9:00",
"10:00",
"11:00",
"12:00",
"13:00",
"14:00",
"15:00",
"16:00",
"17:00",
]
hour = random.choice(lista)
df = pandas.read_csv("new.csv")
date = df.iloc[random_date][0]
# 1 is substracted from that cell as 1 slot will be assigned to the user
if df.loc[random_date, hour] > 0:#here is what you asked for
df.loc[random_date, hour] -= 1
else:
print(f"No Vacant Slots in {random_date}, {hour}")
df.to_csv(r"new.csv", index=False)
print(date)
print(hour)
Here's another alternative. I'm not sure you really need the very large and slow-to-load pandas module for this. This does it with plan Python structures. I tried to run the simulation until it got a failure, but with 365,000 open slots, and flushing the database to disk each time, it takes too long. I changed the 100 to 8, just to see it find a dup in reasonable time.

I get this error when I run the script and I cannot see the solution. This program is supposed to draw a giveaway from a sqlite3 file which has the number of raffle tickets for a user. And recently the program the gives that creates the sqlite3 file updated some stuff (The script is made by me) and I can figure out the solution.

All your other SQL columns are capitalised, any chance that's why it's not finding the viewer_id column? Maybe it's Viewer_Id or similar?
If you sql execute 'HELP TABLE Viewer' and print what it returns, it will give you an outline of all of the columns in that database table, so you can make sure you have the capitalisation correct, or whether the column actually isn't there at all.
I am designing a task manager for a month using graphics in python. I have created the calendar for the month of July. I would like to display the tasks for a given date, add new tasks, remove/delete tasks and save the changes to a file.
The maximum number of to do tasks for any day is 5. Initially, the list of tasks are read from a file. Each row in the file contains the date followed by a list of semi-colon separated tasks for that date. The following shows an example file:
1; Go to class;Book Train Ticket
2; Call Home
3; Wash the Clothes
7; Submit the Assignment Online
8; Give Assignment Demo;Prepare for Major
10; Take the Exam
11; Go Home
To the right of calendar, there is a textbox to enter a new task to the list of to-do tasks for the date currently being displayed. After entering the new task in the textbox, I need to click on the ’ok’ button to add it to the list. As soon as the ’ok’ button is pressed, the list of tasks being displayed should be refreshed to reflect the addition of the new task. The textbox should be cleared after the changes have been incorporated into the task list. Here's my code:
