ATE - if you want us to backtest and suggest improvements for you, that is planned to be $49 per trading system. However, if we can't improve the system, or it turns out to be a really good system and you let us use it, we'll refund all your money. If you want us to do the automated trading for you on our servers, that is planned to be $149 per month.
Groups - these can be any price, because it's up to the owner to set the price. Some might be free. You can create your own group, if you want. (You can create your own group right now, if it's going to be a free one. Just contact us to set it up).
