Hi Guys, I'm separate my question here from the Business plan thread. Hope to see some views on this if it is my own thread. I'm always wonder which one comes first. Trading Plan or backtesting? If we write a trade plan based on a strategy that is not proven profitable yet, do we still write that plan? If we wrote the plan before back test, when do we start to alter the plan if we feel a particular plan is not up to expectation? Anybody has this dilemma before?
