A new Zorro version was released to the Zorro beta forum. Version 1.02 has the following new features:

- Various bugfixes and improvements to the simulator.
- The TrailStep variable can be used for adaptive trailing.
- The indicators.c library is now pre-compiled, which saves ~1 second compile time when starting a strategy.
- The last 3 months were added to the historic price data.
- NZD/USD was added to the default assets.
- The chart viewer now also works under Win XP.
- Trading costs and streak probabilities are now separately listed in the performance report.
- The Z1 and Z2 strategies were modified; they now use the same parameters for long and short trades. Previously they used different parameters. Using the same parameters has advantages and disadvantages; training is faster, the strategy is more robust, and the parameter quality is better due to the higher number of trades. On the other hand, parameters now don't consider asymmetries in the markets, which reduces the performance. We found that the advantages outweigh the disadvantages.
- Workshop 6 was also modified for using the same parameters for long and short trades. A new chapter about improving a strategy was added to workshop 4.

Zorro 1.02 is currently available for beta test. If you're interested in testing this version, please send me a PM and I'll open the Zorro beta test forum for you.
