Quote from FXTraderWill:
I personally recommend sizing up slowly. See if you make more money trading 1200 shares and can still follow your discipline, then size up to 1400, 1600, and maybe you skip 1800 and go straight to 2000... but practice trading with 1200,1400 and 1600 first. You'll be able to double your money, or make 190% the amount you made weith 1000 shares, most likely. especially if you're position trading in liquid stocks.
that's probably what i will do, up to now normal entry 2x500 shares..
now considering 2x600.
