Im really enjoying Zorro also. I went to university for a few years and was doing software engineering writing mostly in Java but I never finished and this is the first coding Ive done since then really. What I love is that the program and language is super easy to understand and learn because of all the inbuilt functions already.

In regards to your second question Ive yet to really program any super profittable strategies on my own yet, Ive mostly played around with scripts that were posted like the7 and Hucks Trend Catching System but I have been playing a round with a few of my own ideas without much luck mostly with lower time frame strategies. Personally Im finding that making stategies that preform well with walk forward optimizations seem to do best on the daily timeframe with moving averages whether they be an EMA/SMA or LowPass, quite a few variations of the7 and Hucks system Ive got to return over 200% annually but what Id really like to design are some 1 and 5 minute scalping strategies that hopefully can get over a 1000% return annually. Thats my goal anyway.
