Trading on margin works both ways, in bullish market leverage works good but when the correction will appear, all of your capital, including profits will be disappeared before you log in to your exchange/broker account.
If you use 2x S&P 500-ETF and suddenly S&P dropped to 100 points, that means you will lose 200 points before you close your trade.
