The day turned out to be quite a mess, and this time, it's all my fault.
First, I traded setups that I was not familiar with. Then I decided to use the chart trader instead of IB's price ladder to execute my trades, and totally lost my edge - I got in and got out at all the wrong places, couldn't figure out the absolute dollar amount of my stops, couldn't focus on my charts (what an irony, given that I was trading off them) and was totally out of sync with the market.
I have to say, this feels like the worst trading day ever.
I'm just glad that this is the last day of this week.
