Close position Binance Futures with ccxt

Question

I'm trying to close a position on Binance Futures using ccxt ccxt-1.39.93, Python 3.

# fetch position
position = binance.fetch_balance()['info']['positions']
pos = [p for p in position if p['symbol'] == "ETHUSDT"][0]

ticker = get_binance_futures(fetch_only=True)

close_position = binance.create_order(symbol=symbol, type="TAKE_PROFIT_MARKET", side="buy", amount=pos['positionAmt'], price=ticker , params={"closePosition": True, "stopPrice": ticker})    

I want to close current position. But got this error:

ccxt.base.errors.ExchangeError: binance {"code":-2021,"msg":"Order would immediately trigger."}

Is there a simple way to close current position at market or spot price for a given symbol ?

Answer 1

After somme struggles I finally found a solution.

close_position = binance.create_order(symbol=symbol, type="MARKET", side="buy", amount=pos['positionAmt'], params={"reduceOnly": True})    

Using reduceOnly params did the trick. No need to setup a price as it is MARKET.
