For a buy only and exit strategy, when I run the following code I am able to see the chart and data and the indicator. However it doesnt appear to run any trades. Is this because I need trade analyzers. I did this with a strategy before and it worked as designed. But when I changed the data to intraday it gave me loads of problems.

I end up with the following.

import backtrader as bt
from datetime import datetime

class SmaCross(bt.Strategy):

params = dict(
    pfast=10,  
    pslow=30
)

def __init__(self):
    sma1 = bt.ind.SMA(period=self.p.pfast)
    sma2 = bt.ind.SMA(period=self.p.pslow)  
    self.crossover = bt.ind.CrossOver(sma1, sma2)  

def next(self):
    if not self.position:  
        if self.crossover > 0:
            self.buy() 

        elif self.crossover < 0:  
            self.close() 

In[8]:

data = bt.feeds.GenericCSVData(
dataname="test.csv",
dtformat='%Y-%m-%d %H:%M:%S',
open=1,
high=2,
low=3,
close=4,
volume=5,
fromdate=datetime(2020, 1, 1),
todate=datetime(2021, 11, 4)

)

cerebro = bt.Cerebro()

cerebro.adddata(data)

cerebro.addstrategy(SmaCross)
cerebro.run()
cerebro.plot(style='Candlestick')

Hello

I keep getting the following error module 'backtrader' has no attribute 'Timeframe'

I am trying to plot using intraday data and not many really good samples out there. Plotting daily data is fine
Code is as follows

import os, sys, argparse
import backtrader as bt
import backtrader.analyzers as btanalyzers
import matplotlib
from datetime import datetime
import backtrader.feeds as btfeeds

data = bt.feeds.GenericCSVData(
dataname='C:/Users/brand/NQ21.csv',
datetime=0,
fromdate=datetime(2021, 1, 3),
timeframe=bt.TimeFrame.Minutes,
dtformat=('%Y-%m-%d %H:%M:%S'),
open=1,
high=2,
low=3,
close=4,
)
class Mystrat(bt.Strategy):

def __init__(self):
    self.the_highest_high_4 = bt.ind.Highest(self.data.high, period=4)
    self.the_lowest_low_4 = bt.ind.Lowest(self.data.low, period=4)

cerebro = bt.Cerebro()

data = bt.feeds.YahooFinanceData(dataname = 'NQ20.csv')
cerebro.adddata(data)

cerebro = bt.Cerebro()
cerebro.adddata(data, timeframe=bt.Timeframe.Minutes, compression=5)
cerebro.addstrategy(Mystrat)
cerebro.run()
cerebro.plot(style='bar')

@davidavr Thanks but unfortunately I get a different error when putting that into cmd...
ERROR: Error [WinError 2] The system cannot find the file specified while executing command git clone -q https://github.com/mementum/backtrader.git 'C:\Users\brand\AppData\Local\Temp\pip-install-g_gi_wmv\backtrader_61ddfe02b5664377a282d1e46e60fea0'

Hello, I am trying to run the code below and keep getting the
ImportError: cannot import name 'warnings' from 'matplotlib.dates'
error message. I have read around multiple guthub responses and they all say uninstall matplotlib and perform the following
pip uninstall matplotlib
pip install matplotlib==3.2.2
I do this from the cmd and nothing gets resolved.
Just note I am trying to run this from Jupyter notebook, so not sure id the dates.py in there is getting updated properly.
Thank you
