so a trading plan takes into account what the market is doing and then you take informed trading decisions based on that.
now if the market changes what it is doing, and it can and does frequently, what it is doing then you need another or different trading plan.
so, if someone talks about his trading plan, then you know his plan is limited and useless .
Now take Brooks he talks about what the market is doing, then he has numerous plans that deals with that particular market environment and so Brooks has a variety of trading plans that fit, hopefully, what the market is doing, at that particular time.
You don't have a plan, man. You have been proselytizing Al Books for years.
