first post.question on day tradeing

I am paper trading on TOS, and was wondering if I am doing something wrong..I am buying(in truth shorting) stocks on the days high(well waiting for the first sign of a pull back) in increments of 1500,2500,5000 depending on volume(sometime volume is low, and trades dont happen in the real world right?)..Then buy them back(completing the short contract) when they go down a certain amount or certain percent. This is also done in similar increments as the opening of the trade...for instance I bought(shorted..not sure what to call it) AKS today at 2500@2.44, 2500@2.46, 5000@2.45 total of 10000 ave price 2.45..waited 30-45minutes..sold it?bought it back? at 2500@2.36 5000@2.34, then change/ from 2500@2.32 back to 2.35(is this allowed in the real world?)..all fired(made over a $1000.00 in paper..lol!!)..If I have $50,000 real cash(qualify for day trading, above the 25K..margin account, but only using my money. No loans/margins? If I loss[yea, gambling terms] I dont want to compound it), and did this in the real world would it be legal? Would it work(been doing this with similar results for 2 weeks now..so I must be doing something wrong or illegal..not all winners but averaging 2.155% daily on 50k) ..am I missing something? I dont want to get all excited, and sink all my savings into this only to find out I am wrong, doing something illegal, just getting lucky(this is true to a point), something else I am not seeing, not understanding...Anything would be helpful to alleviate my concerns or give me something to think about, help me avoid a terrible mistake..Thanks Take Care.
