I guess Earn2Trade want's to be more sure that besides the trailing, to pocket money a different way. You might ask yourself, "what if a trader decides to blow that hard earned money in one day, where is my share?"
Where is the futures company that have one combine/tryout, that does not have a trailing, does not have a time limit to be funded, that has a onetime fee, and if funded will cover all the cost?
Not to speak for E2T, I don't really have a dog in the fight, and agree with your pros and cons of the various outfits. 2 comments, maybe will help.
As for the issue about feeling like its unfair they take their share once a month if you don't do a withdraw, one way around it would be to do regular withdraws. Do two a month (assume you can do multiple in a month from what I've read), and if you don't really have enough profit to make it worthwhile, well then the 20% won't be a big hit regardless. Just my opinion.
As for the 1 fee, I know E2T has a regular gauntlet, it doesnt get talked about really at all, but its a 1 time fee, 60 day evaluation for people looking for a more long term solution. I think the rules about trailing stop losses are fair, if they didn't and people were just swinging wild all over the place it's not really the type of trader they would want to fund anyways. All the programs are a test, the parameters are there and its up to us to play by them. I don't think its really fair to expect them to refund your fees for passing either, youre basically asking them to give you the evaluation for free if you pass. They are a business and have to make money. Honestly if people are looking to make trading a career, the fees for combines should be small relative to the profits you make in the long run.
