So here's my idea. Please do what people here do best. Critique. Best to point out the flaws now before I or someone else goes through with it.
First, I'd have to screen people for personality fit and technical ability. This is probably the most painful part.
Then, I'd get 5-7 computers with 2 big monitors each and hook them up to my network but in a separate office place. I'm guessing this to cost about $50K.
Upon arrival, I'd give people access to any tax, clearing and financial statements I have for up to 2 hours. I'd answer questions about them. At this point, if anyone felt uncomfortable proceeding I'd pay for their return flight back home.
The rest of the day we'd discuss some aspects of manual trading, exchange data, speed and matching algorithms. I'd describe general characteristics of automated trading that I've seen work. Then I would give them access to our tick data. It's the full direct access feed from several exchanges. With nanosecond time stamps. I could point people in the direction of products that I think are good for automated trading and what features might be worth investigating. Or they can look at whatever they want. After a few days of this at least someone should have found something interesting. We would code up the strategy and start back testing and tweaking. Might do a few different strategies. Class could vote on which one to continue with and then spend several more days of tweaking and optimizing.
At the end, they'd get to keep a copy of the strategy part of the code and take it with them.
If it looks good, I'd run the strategy and pay out 20% of the first 6 months to the class.
My guess at probability of success (annual numbers). I'm pretty confident in my accuracy here:
$0. 30%
$100,000 or less. 5%. (I wouldn't keep running this)
Up to 300,000. 10%
300-500k. 20%
500-700. 20%
>700. 15%
So, my expected gross profit is around 300k/year per class.
Expenses
Payout to class. 30k
One time setup costs. 50k
My time / opportunity cost. 100k
Some meals. 3k
Not like I'd be making a killing, but it would help brake up the monotony of trading without feeling like I'm totally wasting my time. And, while we wouldn't focus much on manual trading directly, some of the same principles apply and there could be some crossover. Going through this experience certainly shouldn't be detrimental to someone's trading.
