Yes it is very possible and you can ask your broker to provide you no leverage at all. But the returns will definitely not be worth it and you will still be vulnerable. You would first of all need a huge amount of capital for your trading, which most traders don’t have. A trader is most likely be tempted to take bigger risks to get better returns, but that will certainly expose him to huge losses also. Most traders recommend leverage of 50:1 or 100:1 and always calculate what percentage of your capital you want to risk before entering the trade. Generally it is not recommended to trade without leverage as one lot consists 100K units.
