Cryptopia fetchOrders requires a symbol param

Is the following message the result of a bug or is there a suggested way to work around it? (it works for other exchanges like Poloniex and Bittrex)

(node:2040) UnhandledPromiseRejectionWarning: Error: cryptopia fetchOrders requires a symbol param

• OS: Linux
• Programming Language: JS
• CCXT version: 1.10.492
• Exchange: Cryptopia
• Method: fetchOrders

So what I ended up doing is working around it like this:

1. get a list of currencies in my Cryptopia portfolio using fetch_balance(),
2. check which one of those currency pairs are an actual market on Cryptopia: exchange.load_markets() and exchange.symbols,
3. Override the Nonce for Cryptopia as explained here.
4. Fetch orders for every supported symbol.

The downside of this is of course that if I have an order for a currency that I don’t already hold, this will miss it 😦. That’s too bad because the exchange does show all of them.

Here’s some of my code for this:

  def get_open_orders(self):
    try:
      return self.api.fetch_open_orders()
    except ccxt.errors.ExchangeError as e:
      if "requires a symbol" not in str(e):
        raise e
    # this is an exchange that requires a symbol for orders, e.g. Cryptopia
    currencies = self.get_balance().keys()
    currency_pairs = [(c1, c2) for c1 in currencies for c2 in currencies]
    possible_symbols = ["{}/{}".format(c1, c2) for c1, c2 in currency_pairs]
    supported_symbols = self.supported_symbols()
    symbols = [s for s in possible_symbols if s in supported_symbols]
    order_groups = [self.api.fetch_open_orders(s) for s in symbols]
    orders = [o for og in order_groups for o in og]
    return orders

  def get_balance(self, mode="total", include_low_values=False):
    balance = self.api.fetch_balance()[mode]
    if not include_low_values:
      balance = {k: v for k, v in balance.items() if v > 0.00000001}
    return balance

You mean fetchOrders ?

Yes, of course, made a typo… my bad.

Having an easy way to see if an exchange is capable of this would be nice indeed. The same thing with the capability of market order .

Working on it. 😉
