Yes that is true. Unfortunately (for you) everyone one else has lower execution costs than you as well. Everyone has lower execution costs than retail traders :)

I guess I was referring to the market data/technology advantages - not all advantages.

What to do about the cost advantage - legislate a fixed brokerage fee for all traders? Can't see the large (institutional) traders being happy about that, is it fair for a super fund to pay the same bro as a retail investor?

You need to be careful to not put everyone doing something you don't like or dodgy in the HFT bucket. You don't need to be a HFT to target a debt covenant trigger. A human can do that just as well, and is at no disadvantage. It would be a waste of HFT resources to target this kind of "opportunity".

HFT are very focused firms, and have extremely tight risk limits (tighter than anyone else in the market). Targeting a trigger is not something HFT have an advantage in, and would be way beyond the kind of risk they would be willing to cary.

Totally agree. One of the reasons I've proposed TimeMatch to take the market back to the needs of the genuine liquidity providers..

Yes, though I think the cure can the worse than the disease. I am hoping to reform the lit market so no-one wants to leave and trade in the dark. It is possible, just takes some creative thinking.

Dark pools are less regulated, and suffer from liquidity fragmentation - I'm trying to not have to pay that price!

Check out TimeMatch on my blog, I'd be interested in your thoughts!
