Jika, Anda ingin mengumpulkan data perdagangan bitstamp dari websocket mereka dalam resolusi yang lebih tinggi dalam jangka waktu yang lebih lama, Anda dapat menggunakan skrip log_bitstamp_trades.py di bawah.
Skrip ini menggunakan pustaka websocket-client python dan pusher_client_python, jadi instal mereka.
#!/usr/bin/python
import pusherclient
import time
import logging
import sys
import datetime
import signal
import os
logging.basicConfig()
log_file_fd = None
def sigint_and_sigterm_handler(signal, frame):
global log_file_fd
log_file_fd.close()
sys.exit(0)
class BitstampLogger:
def __init__(self, log_file_path, log_file_reload_path, pusher_key, channel, event):
self.channel = channel
self.event = event
self.log_file_fd = open(log_file_path, "a")
self.log_file_reload_path = log_file_reload_path
self.pusher = pusherclient.Pusher(pusher_key)
self.pusher.connection.logger.setLevel(logging.WARNING)
self.pusher.connection.bind('pusher:connection_established', self.connect_handler)
self.pusher.connect()
def callback(self, data):
utc_timestamp = time.mktime(datetime.datetime.utcnow().timetuple())

self.log_file_fd.write(line)

if __name__ == '__main__':
log_file_path = sys.argv[1]
log_file_reload_path = sys.argv[2]
main(log_file_path, log_file_reload_path
dan konfigurasi file logrotate
/mnt/data/bitstamp_logs/bitstamp-trade.log
{
rotate 10000000000
minsize 10M
copytruncate
missingok
compress
postrotate
touch /mnt/data/bitstamp_logs/reload_log > /dev/null
endscript
}
lalu Anda dapat menjalankannya di latar belakang
nohup ./log_bitstamp_trades.py /mnt/data/bitstamp_logs/bitstamp-trade.log /mnt/data/bitstamp_logs/reload_log &
