The profitability of this system from 2007 to 2011 is very impressive. However, recent performance suggests its glory days may be over.

The developers of the system are disciplined and self-confident. The system will probably be alright in the long run, but does not appear to have a significant edge. It does well when the market does its "normal" oscillations, but is completely wrongfooted when the market tanks decisively. It adds insult to injury by trying to catch falling knives that no good discretionary trader would touch. This of course is a hard thing to avoid for any mechanical system. Buying deep in-the-money call options of a market index probably has better risk/reward characteristics, and is much much simpler.

I assumed that TOPAZ system is resilient enough to withstand the US financial crisis of 2008, it should withstand the current European crisis. Unfortunately, this does not seem to be the case during last 3 months. The system doubles down for losing positions and there is very little chance for a stock to recover in 12 days in this volatile market. So far, this system fails miserably in bearish and volatile market. The developer also raised his subscription price by 50 pct. recently and should consider lowering it due to very poor performance.

Would be nice to be able to trust the system right now, but with 4 months of losses wiping out an entire year of gains, the drawbacks of 100% automation outweigh the positive for the near term. In these unprecedented market conditions, it is impossible to have reasonable hope that any gains are not going to be destroyed by the system tripling down on spiraling stocks that have simply no realistic chance of recovering within the automatic 10 day timeframe. Nor has any attempt been made to limit the number of buys: C2 automated margin calls on bad days can cause a lot of damage even for subs who judiciously manage their own position sizes. Rather than sitting here worrying about “missing” any gains, I think it’s time to shut it down and sit it out until (if/when) it stabilizes.

Despite its seemingly complex buying and selling rules, the system is essentially a leveraged exposure to the NQ100 and is at almost all times fully invested. As such it is highly correlated to the NQ100 leveraged x2. With its high trading frequency and thus high costs plus a high monthly subscription charge, it remains doubtful whether long term the system would outperform buying and holding QQQ with x2 leverage.

Topaz is the best stock strategy I've found on C2 and the only one I consider safe enough for my retirement account. It is flexible and profitable, both short term and long. Autotrading it is easy and there has been a steady upward equity climb since I joined (although it had to weather the tsunami as did a lot of other systems.) Sometimes the mandatory 10 day selloff can be a frustrating if a position is in the red, but the overall equity curve still steadily rises. The beauty of this once a day system is that if you want to manually manipulate any of the positions, it is easy to do so, even with autotrading enabled. Developer's website and comprehensive FAQs are excellent.

Topaz has been an exceptional system by any reasonable standard. Though any system will have significant draw-downs, Topaz does an excellent job of recovering from the worst of them. The developer has also been quite responsive to my e-mails. The worst I can say is that the e-mail spam has sometimes filled up my inbox, but I expect this will be fixed.

Five Stars for an intelligent strategy and for customer service! I have been very happy with Topaz over the last few months that Ive been trading on the system. Its very easy to trade manually, and has become easy to trust. He knows when to acknowledge a loss, and when to capture gains. I wish I had found this system earlier! Oh yeah... Performance has been excellent - the reason I subscribed in the first place!

ottimo sistema, ottima persona, affidabile e onesta.. ho guadagnato molti soldi con topaz nq100 m...!!! di gran lunga il miglior trading system che abbia mai avuto...! lunga vita a TOPAZ...!!!!!!!

I would highly recommend Topaz System. I have been searching for a system to trade for quite a while. The basics of the system makes sense and it is easy to trade manually as well (10-15 minutes per day, before markets open so easy to manage). I would recommend choosing a broker with per share commissions as the flat rate charged per transaction would not work well with this system since there are quite a few transactions every day. The other great thing about this system is that it's owner, Dr. Koch is always available to answer questions and concerns. I was extremely impressed with his professionalism and that just go to give me more trust into the system. He answered every questions I had within a few hours. For those reasons, I would highly recommend trading Topaz System.

Since I discovered C2 earlier this year, I have been in and out of several systems trying to find one that matches my trading style and investment goals. I have definitely had my share of disappointments. But several months ago I found Topaz NQ100 M and I have been extremely happy with the results. The provider appears to be a smart and professional trader and is great at communicating with his subscribers. The longevity and track record of this system speaks for itself.

I have been a subscriber to Topaz for the last couple months.. It is in my opinion the best system on Collective2. Well deserving of a 1000 rating.

This is the 3rd C2 system I have subscribed to and the one I like the best. Topaz finds oversold stocks and sells them within 12 days. I like that it only takes a few mintues in the morning to trade the system and I do not have to check in during the day. I do not use margin, so each trade I use 5 percent of capital. Topaz is not for small accounts since some days there are 20 trades,but most trades are positive with a occasional big loser

I am impressed with Topaz. Its very consistent, low risk and easy to use. I would recommend it to any level trader. C2 rating of 1000 is nothing to sneeze at.
