Hi Asif,
There must be any number of ways you can play around with the system! But what is so good about news anyway, by the time you get it the market has already reacted. I never ever read the news except out of idle curiosity after the event. There are of course some events which can be traded, eg Non-Farm Payroll, but you don't need Concept for that. Why don't you devise a method based on your idea, and let us know how you get on?
In my opinion, anyone buying into Concept should just stick with the system. You don't buy a dog and then bark yourself. Or maybe, if it ain't bust don't fix it. If you are already a successful independent trader, why would you need Concept, except to spend more time really living?
As to your idea of using tighter stops and taking profits early, I think you would be on a loser. Too tight a stop loss will see you out of trades before they have had a chance to come good. Taking profits too early will kill your profitability. The success of the system depends on letting the good trades run, not on cutting them short. Some of the good trades have netted spectacular profits. I am sure the people who devised Concept have done a lot of work to optimise the trading algorithm. I would not dream of trying to beat it.
