I had 3 larger losses get stacked on top of each other today.  I should have stopped trading after my 2nd loss in a row.

1 loss I above a key level a bit and I used under the key level as the stop.   I shouldn't have entered off the level and if I was going to I should have used a stop close to my entry.

1 loss was a higher priced stock then I normally trade that was ranging large in it's price action.  I stopped out for a quite a loss as it went quickly.  I should have had a stop set close to entry.

1 loss was in the opening minute and I stopped out in whippy price action.

My first trade was a strong loss.  I might have wanted to quit then.  Or at least slow my trading down.
