Well, I appreciate what you wrote, don't take it wrongly but please can you answer me on one question? When you profit, it means someone loses yeah? So in any way someone has to lose, doesn't matter how experienced these traders are, one can't profit without another ones' lose.
And what about to forget targets? I think you can't plan economy because your plan of daily 3% may ruin chance of getting 10% profit or you even won't reach your target so this means your plans failed? And some may start digging to get that planned profit next day combined with tomorrow's plan and it will ruin everything, especially when we talk about newbies.
I surely get your point about one losing for another to profit
But on the issue of setting a 3% profit target and either you take it out and the market rolled out a 10% profit eventually on that same instance after you had gone out, if this thought of had I known or feeling of sadness keep going on, then you now see a trader over staying in a particular market and might be punished with losses.
