Crude's 'Irrationalistiscm'...

Crude was also on the watch list of this trade observer, but this 15 minute chart from Crude in today's market is one example of market's 'irrationalistiscm'. I place a trade within the pointed arrow and put a stop price within the 50% retracement from the green long bar (horizontal arrow), but got stopped out. It drops so hard and got hit hard (like a falling knife). My mistake is putting a late trade, I could have place an overnight trade (which I usually do), but this one is a product of my own irrationalistic behavior/action from the irrationalistic market behavior, it so happen I acted at the wrong time at the wrong side of the market.
