Getting errors one after another

[Abhishek Agrawal]

I wanted to make a range breakout strategy. Mkt opens at 9:15 IST. I want the algo to calculate the range of 1st 15min bar and buy or sell if the price is above high or low. I have a 1 min data.
in this code i am getting an IndexError.
Please help

@Abhishek-Agrawal said in Getting errors one after another:

if self.dataclose[0] > self.datahigh[-1]:

Although I can't see your error since you didn't include it, I suspect the above line is the problem. You are trying to find currnet and previous bar. On the first bar there is no previous bar. This will throw an error.

You need to manually skip the first bar in next with a self.counter of some sort.

def __init__(self):
    self.counter = 0

def next(self):
    if self.counter == 0:
        self.counter += 1
        return
