So, you could perform your analysis and trade off a smart phone by the MetaTrader 4 trading platform app, but I just want to be clear that I don’t encourage people to sit there all day on their phones, because the phone view is a distorted view of the charts and I personally don’t like it. The next tool you need is a trading journal and spreadsheet to track your trading performance. The trading journal / spreadsheet is like a wall you put up between yourself and all those trading mistakes.
