@asdasda load the data into pandas and check the condition of no. of records if it's more than required then load the data to bt.feeds

@rishabmah5 I meant 2016-05-05

@rajanprabu I noticed the other df was timezone aware, I made it tz naive and that solved the issue and I am not getting duplicate outputs anymore. But out of curiosity, do you know why having a tz aware prints duplicate outputs?

@run-out when i open it in excel it is in one column with coma separated values without headers,

used this code to download the file from binance,

import config, csv

from binance.client import Client

client = Client(config.API_KEY, config.SECRET_KEY)

candles = client.get_historical_klines("BTCBUSD", Client.KLINE_INTERVAL_1MINUTE, "365 day ago UTC")

csvfile = open('1min.csv', 'w', newline='')
Klinewriter = csv.writer(csvfile,delimiter=',')

for candlestick in candles:

Klinewriter.writerow(candlestick)

csvfile.close()

Maybe some of this thread helps? https://community.backtrader.com/topic/2/limit-order-with-a-day-valid-never-gets-executed-220/13

@calebsandfort Sure just input earlier data, and then in your next check the date before starting to trade. So for example, you would start your data 2015,1,1 and then in your strategy:

def __init__(self): self.trade_start = datetime.datetime(2016, 1, 1, 0, 0) def next(self): dt = self.data.datetime.datetime() if dt < self.trade_start: return

Or enter trade_start as a parameter.

@prnvat8197 Aah, finally read the documentation thoroughly and did some tickering around, the Generic csv data is required as input

data = btfeeds.GenericCSVData( dataname=datapath, fromdate=datetime.datetime(2021, 7, 1), todate=datetime.datetime(2021, 7, 16), nullvalue=0.0, dtformat=('%Y-%m-%d %H:%M:%S'), timeframe = bt.TimeFrame.Minutes, compression = 15, Datetime=0, High=2, Low=3, Open=1, Close=4, Volume=7, Adj_Close=6)

Thanks to everyone who replied to this thread! Really appreciate the community :D

@vladisld
Thanks man!
Maybe I should read all the docs first and then the repository.

@run-out That did not sound odd at all :P

Thanks this works, this is what I was expecting it to do.

@run-out Thank you for your reply.
My PC have 64G memory, and AMD 5950X .
Something wrong with my code.
It's OK now.

@run-out see https://www.backtrader.com/blog/posts/2017-07-05-order-history/order-history/, Backtrader provide order-history function to evaluate external historical performance.
