I think you are arguing something different than I. I am open to being wrong, but I think I am making a different point.
You are saying that by having a zero latency trading capability, financial markets are the sign of progress and it is an inevitability that, not only is desirable, but preferred.
That's fine, but not what I am am taking issue with is fully automated system of extremely high volume, low margin, trades that are conducted by bots and have no human interaction other than those that are profiting from them.
I admit I am not savvy enough in this area to argue about whether or not HFT provides more equilibrium to the price of a stock, but I don't see that as a wholly convincing argument as to why HFT is important and adds value.
I am skeptical of that claim, mostly due to my ignorance, so please educate me on the following: The claim that HFT rarely goes wrong such that "ordinary investors" are harmed; who then is the non-ordinary investor who is benefiting from the HFT, and what value are they providing in the markets, other than profiting from HFT.
It appears to be making the claim that HFT is a meta market that the ordinary investor shouldn't even be concerned with except in cases of extreme rarity where a flaw causes them some financial harm/risk.
Again, if this is true - what true concrete value to the world does this meta system provide? I simply cannot see it, and again, I claim awareness of my ignorance, so please explain like I am five.
Thanks!
