dumb trade with ok ending

About an hour ago I sold a vertical 18/19 call on FAS at $0.35. I thought I was selling 19/20 for a premium but the stock was at $18.32. SH*T man, why so stupid I do not know. Market is shooting up and I set myself up for a short? What a mistake, I went with the trade without review and click ok on order. The order went through in a blink of an eye. Funny how the top of FAS stalled and I bought back the call spread for $0.25. After comissions I got $3 gain. Dumb trade indeed when I was fighting a trend. Wasted a day trade too. Now down to two day trades for the week.
