Is your feature request related to a problem? Please describe.
When executing the code sometime Bitfinex limitation (https://docs.bitfinex.com/docs/requirements-and-limitations) reached.
A logic need to be added when it happens and sleep for a time (60s) defined by Bitfinex.

Describe the solution you'd like
A logic like that would be nice to be added:

orig code:

    candle_data.extend(candlestick)
    write_to_console(
        ticker,
        interval,
        candlestick,
        live,
        setup_table(),
    )

..suggested code:

  if (len(candlestick) == 3):
      if  (candlestick[2] == 'ratelimit: error'):
          print('limit exceeded. sleep for 60s')
          sleep(60)
          continue
      break
  if len(candlestick) > 0:
    candle_data.extend(candlestick)
    write_to_console(
        ticker,
        interval,
        candlestick,
        live,
        setup_table(),
    )
  else:
    break

..the above suggested changes handles the situation if date is newer than latest data (even today added causes exception in code running)

Hi,

Just wondering if you have an official library (non-interactive CLI) version of this application? I'd like to incorporate it in a Streamlit application. I have done some experiments a year ago and it is possible.

If I do this again (make it a library) using the latest version (so I can use it in Streamlit), and submit it back to you, would that be acceptable?

Thanks,
Arvindra

Hi - this library is very interesting and perusing and running the code I noticed that there's a possibility of the download period calculation going out of bounds, which throws an error if it steps into the future (i.e., in general there is no guarantee that ((end_time - start_time) % step_size) == 0, except when step_size is set to one day and the interval is 1d ). Here's your code:

    while start_time <= end_time:
        period = start_time + step_size
        candlestick = exchange.get_candles(
            ticker=ticker,
            time_interval=interval,
            start_time=start_time,
            end_time=period,
        )
        candle_data.extend(candlestick)
        write_to_console(
            ticker,
            interval,
            candlestick,
            live,
            setup_table(),
        )
        live.refresh()
        start_time = period
        time.sleep(_RATE_LIMIT)

... whereas I suggest it should be (period has been renamed to period_end):

    while start_time < end_time:
        period_end = start_time + step_size
        if period_end > end_time:
            period_end = end_time
        candlestick = exchange.get_candles(
            ticker=ticker,
            time_interval=interval,
            start_time=start_time,
            end_time=period_end,
        )
        candle_data.extend(candlestick)
        write_to_console(
            ticker,
            interval,
            candlestick,
            live,
            setup_table(),
        )
        live.refresh()
        start_time = period_end
        time.sleep(_RATE_LIMIT)

(step_size should probably also be adjusted based on the interval, though I haven't shown that.)

Hope that makes sense.

Thanks,
Arvindra

Hi - Just wondering why Open and Close values are assigned as indexes 2 and 1 respectively, and not 1 and 2?

The Bitfinex API docs shows that it should be 1, 2.
