```python

import numpy

EX_COINBASE = 0
EX_BINANCE = 1
EX_ALPACA = 2
EX_GEMINI = 3
EX_ALPACA_C = 4
EX_KRAKEN = 5

def signal(ex, pair):
   bars = get_bars(ex, pair, 86400)
   if bars:
      close = numpy.array([x['c'] for x in bars])
      rsi = talib.RSI(close)
      print('Python: %s -> %s %f %f %f %f %f' % (pair, bars[-1]['t'], bars[-1]['o'], bars[-1]['h'], bars[-1]['l'], bars[-1]['c'], bars[-1]['v']))
   return None
