Make it short man if you can.......
Market cannot be define by a line or anything else.....the moment you define it you trap yourself and become prisoner of your own concept cutting your view out of the many possibility the market may be offering.
Lines as with any technicality are a subjective perceptions and nothing more.... a trader might use them to create an island to protect herself from a sea of uncertainty...... and she will be wise in my humble view working in a direction that relates to her personality.....to navigate without constrain.....
Trying to impose my idea to others only shows I am trying to convince myself of something I am not totally sure about.
