You might try real trading with very small position sizes like 25 or 50 shares, etc. Risk is limited but you will actually have to manage your positions. Then just multiply your gross earnings/losses to get your results by the actual number of shares you might have taken if you were trading full positions. Then just subtract commissions as appropriate.
So for example if you trade 20 shares and make $2 per share but would have traded full position of 200 shares then multiply your gross earnings of $40 by 10 to get your gross earnings on the full position, then subtract commissions.
