Before the trade
Write sometning about your psyhology thinking before trade? it is a little disapointmet day because two trade went south
Describe the trade. What you see? price channeling so price will go down to the resistance point

After the trade
What have I done well for this trade? Predicion of the channel was right
What can I take away to help with later trades? that you will make a rule for the sideway channels to put protective stop
