Well you could check out the source code/script of the Ichimoku bot on cryptotrader.org.
Not sure how far that would get you, I'm no coder and don't really understand Ichimoku apart from a couple of videos I've seen about it, but it's a start.
I've been live testing the Ichimoku bot on cryptotrader for nearly a month now and so far it's been doing quite idiotic trades, resulting in a 10% loss. I've only given it a small amount of coins to play with so I don't mind too much, will wait and see what it does after the month is over.
I guess the takeaway lesson is, if you don't understand the code, then it's potluck.
