Hey Michael, I posted the description of my strategy to the Wall. Can I get my 5 extra points? I am looking to kick Kevin Saunders off his throne.

It does seem quite high. However, if you put the numbers together, it actually looks reasonable to me: C2 has 65,000 members. Let's say that only 0.2% of them subscribe to the top-performing system, which charges a typical $100 per month subscription. Then as the system developer, you'd end...

Well, let's see if we can go by the empirical evidence. There are 20,132 trading systems listed at www.collective2.com. Among those, only 19 systems have the Sharper ratio greater than 2 over the last 365 days. So, you'd be in the top 0.1% if you accomplish this. That is, you'd beat 99.9% of all...

Hmm, the "risk of loss" has gone up as a result of two new winning trades? That doesn't seem right. I suggest you guys disclose your performance formula, and we'll talk about it.

I am not sure if the "dumb money" is is a good argument in favor of the hedge funds. The passive market index also has lots of "dumb money" (i.e., the money invested by the people who have very little or no experience in investing and trading), yet this passive dumb index outperforms the other...

Indeed. Here is the performance of hedge funds vs the balanced market index over the last 9 years: Never mind the 20% returns. You'd be lucky if you ended up with a 2% return in your particular hedge fund.

With regards to the RAPA score, I noticed something peculiar. When I uploaded my trading history via the Flex XML ending Dec 24, my RAPA score was calculated as 81. On Dec 26, I had two new trades, both winners, and both within the normal size. When I uploaded these additional winning trades, my...

It appears to be gross. Here is the exact quote from C2: "The top-grossing system on C2 has earned over a half million dollars."

Not to mention that the OP plans to trade for "1 hour". Welcome to the 95% club! :)

According to Collective2, the top system made $565,000 in subscriber revenue: http://www.collective2.com/become-trading-system-developer It doesn't say over which period of time, but let's assume that it's over 3 years. With that assumption, this means about $188,000 per year. So what...

The H1B guys are making $200K a year? Damn, how do I become an Indian?

Do you mean a sorted Map, like TreeMap in Java? My implementation is suited for Interactive Brokers API, so sorted map would not work because the API wants to update a specific level in the DOM.

If there is IT worker shortage, the laws of supply and demand would bring up the compensation. That's not happening. I think what we see instead is that there is a shortage of very cheap IT workers, like the ones who are willing to code for 30K/yr while they are in the U.S. on the H1B visas.

I predicted that if I did the right thing, it would pay off. It did: I am up about 50% this year.

Here is my implementation. I never benchmarked it, but it has to be in the order of nanoseconds for each operation. package com.jbooktrader.platform.marketdepth; import com.jbooktrader.platform.marketbook.*; import com.jbooktrader.platform.util.*; import java.text.*; import...

I thought about this for quite a while even before this discussion has started. It certainly makes sense to include the length of the trading history in the ranking equation. However, I think that the number of trades is equally (if not more) important than the length of the history...

Right. Shadwick and Keating themselves warn against using a single point in the Omega function to rank the strategies. Rather, they insist on the comparison of the entire function. They apparently have something what they call the "F2 score", which ranks the entire thing. I was going to use it...

I agree. What I found surprising is that I made it to the top, even though my record is so short. In my own ranking equation which rates my trading systems, I use (among other things) the term sqrt(number of trades) as a multiplier, which essentially rewards statistical significance, or to put...

Michael/mickson, thanks for making this service and website available. I signed up and uploaded my IB Flex statement by following the instructions, and it was straightforward, except a few minor things where your instructions referred to certain menu options in IB which have apparently changed...

This is an interesting one. I started analyzing it with the expectation that I would get an unambiguous result from it, but it came out not so clear. So, let's assume that each setup (let's call them setup A and setup B) had triggered 100 times. This is what would happen: Net Profit: $5500...
