1. The options graphing software and thinkorswim compete for bandwidth and RAM. This makes execution and analysis difficult. The slightest difficulty, when one is running a complex book, can lead to escalating losses.
2. Thinkorswim mangles option positions, usually because it operates on a first-in, first-out algorithm and because its algorithm assesses risk differently than my graphing software. This makes holding complex positions in a single underlying difficult.
3. The max loss taken in January reverberates to the present, insofar as my attempt to immediately bounce back lead to the establishment of complex positions that were chopped up by the programs. The lingering affects of loss present difficulties.
