could you explain why you think it should be illegal? what exactly do you mean by computer based? can i use a computer to help me decide what to trade? if the computer tells me what to trade and i press a button to agree with it and do the trade is that OK? sincerely trying to understand your perspective and how one might possibly implement it.
What I mean is that now computers algorithms are making the trades, it is so fucked up now that people pay hundreds of millions of dollars to be physically near the stock exchange so that they have less lag.
I should have been more clear, computer based autonomous or semi-autonomous algorithms should not be allowed to trade.
