How to execute Bybit futures trades?

I’m having trouble finding details on how to execute bybit futures trades. Can someone provide some examples of buying/selling longs and shorts on bybit?

I have this code to get into a long position with ‘buy’ and I can get into a short position using ‘sell’, but I don’t know how to close the positions:

exchange_id = 'bybit'
exchange_class = getattr(ccxt, exchange_id)
log.info(f"exchange id: {exchange_id}, api_key: {api_key[:5]}, api_secret: {api_secret[:5]}")
exchange = exchange_class({
    'apiKey': api_key,
    'secret': api_secret,
    'enableRateLimit': True, 
    'options': {
        'defaultType': 'future',
        'adjustForTimeDifference': True
    },
})

# go long
exchange.create_order('BTC/USDT', 'market', 'buy', 0.05)

# go short
exchange.create_order('BTC/USDT', 'market', 'sell', 0.05)

I’ve also tried adding the options for ‘reduce_only’ and ‘close_on_trigger’ but it won’t close the long/short positions:

    params = {
        'reduce_only': True,
        'close_on_trigger': True,
        'time_in_force': 'GTC'
    }
    # order = exchange.create_order('BTC/USDT', 'market', 'buy', 0.05, params)
    order = exchange.create_order('BTC/USDT', 'market', 'sell', 0.05, params)

@freegab the fifth argument of createOrder must be the price (None for market orders), not params. The params overrides must be the sixth argument.
