binance - oco-order does not work for me (python)

Hello guys!

I am trying to get oco-orders (binance) to work for several hours now, but without any success. I also looked up closed issues with similar problems like this https://github.com/ccxt/ccxt/issues/5966 but it didn’t help me neither.

• OS: Windows 10x64 running PyCharm 2020.3.2
• Programming Language version: python 3.8
• CCXT version: 1.40.30

Here is my code

def placeOco():
    exchange = ccxt.binance({
        'apiKey': "xxx",
        'secret': "xxx",
        'enableRateLimit': True,
        # 'options': {'adjustForTimeDifference': True}
    })

    precision = 8

    thePrice = 0.00002000
    thePrice_str = '{:0.0{}f}'.format(thePrice, precision)

    stopPrice = 0.00001600
    stopPrice_str = '{:0.0{}f}'.format(stopPrice, precision)

    stopLimitPrice = 0.00001500
    stopLimitPrice_str = '{:0.0{}f}'.format(stopLimitPrice, precision)


    symbol = 'SCRT/BTC'
    type = 'limit'  # or 'market'
    side = 'sell'  # or 'buy'
    amount = 26
    price = thePrice_str  # or None


    # extra params and overrides if needed
    params = {
        'test': True,  # test if it's valid, but don't actually place it
        'stopPrice': stopPrice_str,
        'stopLimitPrice': stopLimitPrice_str,
        'stopLimitTimeInForce': "GTC",
    }

    order = exchange.create_order(symbol, type, side, amount, price, params)
    print(order)

placeOco()

This is my error message

Thanks in advance for your time and help!

@don-mao the last price of ETHBUSD is floating all the time, and your price has to be > last price, while your stopPrice has to be < last price, which makes your range very-very narrow which in its turn yields your error. You just have to use a wider range so that price > last price > stopPrice.
