Quote from bevo96:
Just out of curiousity, what type of profit margins do you think the big black box firms run on?
This is a complex question...
Because most algo trading operations...
Are not a standalone business model...
But an adjunct to a medium size firm's more classic trading.
You have to start with what is a MINIMUM professional algo operation looks like ...
Say 2 traders (200K) and 2 engineers (150K) plus office, etc (100K)...
Plus roughly $20K/month in sub millisecond latency technology (250K)...
And you have fixed costs of 700K...
For a professional, but shoestring, algo trading operation.
If you have 20% profit margins...
You would have to make $3,500,000 in trading profit...
And pay someone like IB $2,800,000 in commissions...
In order to BREAK EVEN.
So if you are making 25% return on capital trading at 4:1 leverage...
You need about $3.5-4.0 million in capital to support this.
And this assumes you are in the Top 5% of "black box" operations...
That actually wins in this Zero Sum Game.
It takes about 30 seconds to realize...
That this is not a viable business model...
Because any significant change in the markets or rules...
Puts you out of business.
In sharp contrast...
If you already have a classic, profitable market making operation going...
With nice FAT margins...
You can run "black boxes" as an adjunct...
Because most of your fixed costs are already paid for.
IMO...
The idea that you can start-up a sub-millisecond latency algo operation...
As a standalone business...
Is an ET fantasy held by amateurs.
