@aboda as others here have already mentioned, a standard lot would be a huge amount of risk to take with $1000 in your account. Your effective leverage would be 100:1 which means it would only take a 1% move in the market for you to lose all your money. Remember leverage magnifies both your gains and your losses.
If you want to make a career of trading, you have manage your downside risk, so you can trade for years to come. A key rule of thumb is to risk only 1% or 2% of your account balance per trade.
What was the virtual balance of this demo account? We’re guessing it was much more than $1000. Consider that if this demo account had a $100,000 virtual balance, and the floating losses were $1000, this would have represented a total loss on your $1000 real account.
If you were trading standard lots (100,000 units of base currency or 100K) with a $100,000 virtual balance, then this would be proportional to you trading micro lots (1,000 units of base currency or 1K) with a $1,000 real balance.
Consider trading micro lots, if you want to start live trading with $1,000. On this trade size, you’re risking about 10 cents per pip. That would allow you to risk approximately 200 pips per trade, if you want to risk 2% of your balance ($20), or 100 pips per trade, if you want to risk 1% of your balance ($10).
