I had a big 10x leverage long ltc futures which I opened around $85 I think.  I put in additional orders to capture a 10% dip as to avoid liquidation.  Then I bought some more.  I realized I needed to raise the price of my safety orders so I cancelled the previous one, then got distracted by sudden btc price action.  Then my train arrived and I needed to head off to work and just plain forgot to put them back.  Needless to say the dip occurred, I got liquidated, and if I had put in my safety orders I would not have been liquidated and would have been sitting extremely pretty.
