trades not registering, but strategy is plotting

BMccoy

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)

In[9]:

cerebro = bt.Cerebro()

cerebro.adddata(data)

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

Pls include some data to check if you have enough cash to buy,

Try changing initial cash, set up a size in the buy function and define a notify_trade method (lot of examples just google) .

The crossover analyzer is working so if the buy fuction is executed then order is rejected for any reason.
