Not quite there yet. – Spoof Trader Light Stockmarket Simulator Review

This is app is decent as a game if you are not an investor. However, that said, the charts are hard on the eyes and the interface needs work. In terms of investing, it is extremely lacking in it's technical analysis options, and also in its trading transactions. Stop-loss orders, etc just aren't there yet in any useful way and there are no advanced features. The bottom line is that if you are actually looking for anything resembling a trade simulator, that is useful for detailed technical analysis and back testing strategies, this is NOT it. The closest thing I have seen to an actual, useful, non-game trade simulator is IQCharts' iPad-only Trade Simulator (and even that isn't that great, as the time of this review, despite what they would have you believe).
