OK so lets just say this is a ingenious scam(but not a scam)
lets say 25ms interval that would be 4 trades a second. lets say each trade goes up $0.01 per trade. program the algorithm to only trade when a 1 cent profit is made. first trade $505, 510.5, 515.10, 520.30(first second)... $20 profit first second. after 120 trades(30 seconds) of 1 cent increments, $1650.19.
It just trades so fast and has a computer scanning it. I doubt there is a law against it yet(i have no clue).
*****edit i might have done some math wrong but w/e if it was only 500 stocks a trade it would be $20 every second.
