I kept treating every BTC dip as part of the same swing trade
I have a regular office job, so I usually look at BTC after dinner and trade from the daily chart. Most of my spot trades stay open for a few days. For my last one, I wrote down that I would only add after a later daily candle closed above the level I was watching.
I placed a small BTC spot order on BYDFi Monday night. By Tuesday afternoon I had checked the chart from my phone at work and added before the daily candle closed. The next morning I was entering a third order. Nothing in my original setup called for either add. BTC was lower, and I was using that as the whole reason.
I cancelled the third order. I kept the first position and sold back the amount from the second add after work. Now an add needs its own invalidation level and has to fit inside the total position limit I chose before the first order.
The plan was sitting in my notes the whole time. I had read it before placing the first order and still ignored it less than a day later. That was harder to explain away than a bad setup.
