OHTrader from OHSoftware

To tell the truth, this does not look serious. Almost no information about the product on OHSoftware web page. I have not tried it, you are welcome to do that. All i managed to find, was "Trading Software that includes integrated trading system. You can take a collection of stocks and back test all of them with a click. This device also has reports so you know exactly what has happened, when happened, and especially you know what it is necessary to do". Well, if you are a serious trader, forget this post. The website seems to be created for google ads, not for software.
