binance does not offer 3h candles for 30m extra

[movy]

Very basic stuff: extra candles state that 30m candles will fetch 3h as extras:

and naturally it works fine during backtesting. Yet Binance does not offer 3h candles, so going live is impossible with such strategy, error goes:

  error: 'ValueError: Invalid timeframe: 3h',
  traceback: 'Traceback (most recent call last):\n' +

    "    raise ValueError('Invalid timeframe: {}'.format(timeframe))\n" +
    'ValueError: Invalid timeframe: 3h\n'
}

A simple fix would be to offer extra tf conditionally based on the exchange used. I think manually generating 3h candles not worth the effort in such case.

My bad, I forgot that local candle generation can be activated by user!
