I've struggled with this same issue. I finally broke down and dropped some money on a program call forex tester 2. I just got a few weeks ago and have been very happy with so far. It allows you to start, stop, rewind, fast forward and of course it does have the Ichimoku indicator. They have a good bit of data available and you can save the results of your testing. I really have no complaints and feel it was worth the money as it makes back testing much easier. Here's the link:http://www.forextester.com/
they offer a 30-day free trial. It's been a good tool for me so far.
