Binance API returns with: APIError(code=-1013): Filter failure: PRICE_FILTER

Question

APIError(code=-1013): Filter failure: PRICE_FILTER

I can't figure out what the error is. I am sending this request:

 order = self.client.create_order(
                symbol=symbol,
                side=side,
                timeInForce=TIME_IN_FORCE_GTC,
                type=order_type,
                quantity=quantity,
                price=price
            )

It usually works but occasionally I get the before mentioned error.

Quantity and Price were in my case:

 quantity = 0.0003 
 price= 40022.4

Any ideas?

This error occures when your price parameter does not comply with symbol's price filter's specification. Price value needs to satisfy at least three conditions, which are;

• minPrice defines the minimum price/stopPrice allowed; disabled on minPrice == 0.
• maxPrice defines the maximum price/stopPrice allowed; disabled on maxPrice == 0.
• tickSize defines the intervals that a price/stopPrice can be increased/decreased by; disabled on tickSize == 0.

To get price filter information for any symbol you need to use GET /api/v3/exchangeInfo API. Anyone uses python-binance library can use the following method to get PRICE_FILTER information for the requested symbol.

def get_price_filter(self, symbol):
    data_from_api = self.__client.get_exchange_info()
    symbol_info = next(filter(lambda x: x['symbol'] == symbol, data_from_api['symbols']))
    return next(filter(lambda x: x['filterType'] == 'PRICE_FILTER', symbol_info['filters']))

where self.__client is type of binance.client.Client
