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.
