no, I don't think that high leverage causes higher losses if you have strict management for your money and a good strategy of high leverage will benefit you and your trade will be easier because you will have more money in your balance and you can control more comfortable in your trading and I think high leverage will be great with Forex traders if they can't make good management in trading, even though a number of Forex traders might make excellent management who won't get problems related to high leverage. ]
