If you are claiming there's a bug in Ichimoku example in Backtest->Featured part of the site, which are there for everyone to use, and you don't want to point which bug is it - that's really lame. Don't do such a thing.

I think that the Ichimoku example has a small bug in it but that is based on my initial reading of the docs at ichimokutrader.com. I'll probably share my fix when round 6 opens. It will give me time to research my theory further, I don't see how this is lame.

Well, it's a peace of opensource code you've got for free to work on. Holding back findings about bugs so everyone can continue to work on that same peace of code is lame in my book. You don't have to offer your fixes to everyone, but you should describe the bug.

Why should I do that? Why do you need to insult me? I've already stated that I will probably participate in round 6 and if I do, I will have to release the code.

About open source:

Code:

Nobody should be restricted by the software they use. There are four freedoms that every user should have:

the freedom to use the software for any purpose,
the freedom to change the software to suit your needs,
the freedom to share the software with your friends and neighbors, and
the freedom to share the changes you make.

Hint: Freedom is the keyword...

Until recently, my real life job was to find hard-to-find bugs and vulnerabilities in software and systems, mostly banking software (core banking, treasury systems, mobile banking, online banking...) We get paid a lot of money to do that. Open source or closed source software, it doesn't matter, we still get paid.

Even the restrictive GPL doesn't force you to publish any changes unless you distribute compiled code.

In copyright law, a derivative work is an expressive creation that includes major, copyright-protected elements of an original, previously created first work (the underlying work). The derivative work become a second, separate work independent in form from the first. The transformation, modification or adaption of the work must be substantial and bear its author's personality to be original and thus protected by copyright.

In the particular case of cryptotrader.org, I actually paid Alex to use his service and infrastructure. Regarding Medji or the sample code, I don't know their respective history, where the source code comes from and who wrote it. What I know is that Goichi Hosoda, the creator of Ichimoku Kinkō Hyō is not getting anything from Alex or Medji or any of the traders and software engineers who uses his methology.

If you had just spent an hour reading up on Ichimoku and took a critical look at the code, you would have noticed the bug right away because it is so obvious!! I even thought it was left there as an exercise. (and in the old days, released exploit code would includes bugs and typos on purpose to make life harder for script kiddies and what we would call lamers...)
