That's because you're margin trading. Look, I'm going to explain this once and you'll hopefully realise why you're an idiot, not that I expect you to admit it obviously...
When you margin trade, you deposit a sum, say you stake $100, the broker then provides leverage and backs you with say 10x that sum (or more, depends on broker), so you're actually trading the market with say $1100. You then go short or go long with that $1100, whatever you think etc.
However in order to secure their investment the broker effectively places limits, if the price moves against you as soon as it drops $100 in value the broker will automatically close your position in the market - at a $100 loss. ie. They've retained the $1000 leverage they gave you and you've lost your $100. If you want to go again you need to deposit more money. There's no waiting for the price to come back, it's over, your original stake/money is gone. That's why you've 'lost' after 3 days, because you wouldn't have any money in a month's time when margin trading, you basically already lost your money in a matter of hours (like I say, unless you staked over $5000 to compensate for the dip, guessing you wouldn't ever have staked that much though..).
I can't possibily explain it any more clearly, but I still wouldn't expect you to get it, because clearly you're a moron. You're wrong, you're dumb, I've tried to shed some light, but you're beyond help, enjoy losing your money, goodbye.
