I would recommend to set AutoAdjustECN to false, but UseStopOrder and HardStopTrailing to true. Risk is up to you. Most people here also reduce the MaxSimultaneousOrders setting and up the risk instead.
You noticed yourself that you didn't have trades lately on Thinkforex. Did you check the trade journal for errors? Probably orders could not be opened because of price changes. Thinkforex is too slow in opening of orders and in modification of S/L, in my opinion and what I heard.
Could you provide a link to a good real account using Thinkforex?
People here don't like telling their broker, because they are afraid everybody will go there and overflow the trade-server of the broker, resulting in slow execution like on Thinkforex. But I am using IBFX(AU) successfully for months and others here as well. Performance is still good, see my 1st system.
