I stand corrected in my previous review: "While the system has performed well since I started the subscription in August 2007, I have two minor problems. One with the vendor, and one with C2. First, the vendor states that the max # of positions is 13. Yet, at the time of this review, the system is holding 15. Second, C2 continues to report system performance with margin. In the case of Ruby, it's 100% margin. In the case of some futures systems it is way more. I believe the only rational way to report performance for apples to apples comparison is to show results with no margin and let the user decide on leverage" Dr. Koch is correct - the system is only holding 13 positions. I was confused by the way C2 shows this.

System fails when multiple orders fill. My example is the 11/12/2007 trade of APPL, which is either conveniently or inaccurately left out of the executions page and considered an unfilled, expired trade. In reality, APPL filled before at the signal price around 9:30:50 AM, well before any other trade. While this trade has left subscribers with a big loss in their trading accounts, it has somhow been wiped off the developer's record. Until the developer can clear up issues like this, users must consider the reported results as a fantasy - not truly reflective of what occurs in a real-world account.

This is a swing trading system that buys oversold stocks, and closes open positions with 2.5% target. However, it typically buys those stocks already on a downward trend. Thus by design, the system works well in a bull market (when 2.5% upward swing is natural), but it may lose a large bundle in a distressed situation. Drawdown will be too large. I suggest Dr. Koch to add in stop loss, or other filters to handle this kind of situation? I will rank the system 5 star if it can be demonstrated to preforme as well in a bear market. Overall, I shall say that Dr. Koch has done a good job, and this system is relatively easy to follow. However, use with care.

The system provider breaking his own rules. "While trades will be filled during the day it is possible to trade it with a one time effort per day" not true. Some positions are cancelled after execution. Statistic in C2 does not correspond to actual portfolio status and results. C2 record shows 14 positions, but system should be limited to 13 according system FAQ..

Very impressed with this system so far. Volatile market conditions may have helped but nevertheless as a relatively inexperienced trader it has performed well. I'm using it with an IG spread betting account, meaning I've had to allocate a fair bit of capital for all the orders to open - but when a system performs like this that isn't a problem. Can thoroughly recommend it.
