Wrong decisions and right ones are all down to the luck of the market,,, if we feel that these are all decisions based purely on price. But if we decide with good reason that we will try a trade to go in 1 direction, but if it stops losses us out when it goes in the opposite direction, this is not a wrong decision to me, but the right one.
Wrong decision to me means you change your mind about a trade and do it different from where you started. Not because of anything but emotion/panic/whatever.
So you can still make losses all the time but these are not wrong decisions!
