If you’ve worked with Dr. Van Tharp, or read his books, you’ve undoubtedly seen what he refers to as the System Quality Number. It’s essentially a proprietary measure of the quality of a trading system, and can be roughly interpreted as follows:
- 1.6 – 1.9 Poor, but tradeable
- 2.0 – 2.4 Average
- 2.5 – 2.9 Good
- 3.0 – 4.9 Excellent
- 5.0 – 6.9 Superb
- 7.0+ Maybe the Holy Grail!
Tradervue will now calculate the SQN for any set of trades – it is shown in the stats tables on the Detailed, Win vs. Loss Days, and Compare tabs. Note that since the SQN is calculated using risk-based results, it will only be shown when running Tradervue reports in R mode.
The SQN calculation is available now for all users with a Gold subscription plan.
