What are silly thing in Trading?

my list is as follows, without being exhaustive.

• Extend the defined Stop Loss
  • sometimes when the market is going against me I don't want to lose and move the stop loss. I end up losing more than the stop loss.

• Take to much Risk (To much Lots or the Risk is to big)

• • Add Lots when I should get off to try to reduce the Loss
    • Sometimes when the market is against me I don't want to lose and think I can limit the loss and buy more for the better price.
      But of course the loss is then usually higher.

• • Don`t get out of the Trade, when it is clear that I will reach the Stop Loss
    • In most Times I see, when my Trade Idee (Stop Loss) becomes invalid and I should get out. But I can`t, because of wishing all will be good.
