Demo trading is enough if you have learnt about the trading platforms, developed your trading skills, have knowledge of how to trade, how to use technical indicators, candle stick trading, fundamental analysis. Trading in real money is different from demo trading. Emotions are different and loss will be real. If you think you are confident, can control your emotions, and prepared for the loss also, then surely you can go for a live account. But start with a low amount so that once you develop your own trading strategy and getting returns then you can go for a higher amount.
