    m = Merlion()
      target = 'SPY'
      m.track_symbol([target, 'BITA'])
      bounds = {target: [220, 250]}
      while True:
        symbol, ticktype, value = m.get_mkdata()
        if symbol == target:
          if ticktype == ASK_PRICE and value < bounds[symbol][0]:
              oid = m.buy(symbol, 5)
              while True:
                  ord_st = m.get_order_status(oid)
                  print ORDSTATUS[ord_st]
                  if ord_st == FILLED:
                      bounds[symbol][0] -= 20
                      break
                  sleep(2)
          elif ticktype == BID_PRICE and value > bounds[symbol][1]:
              oid = m.sell(symbol, 100)
              bounds[symbol][1] += 20
