End of Year Accounting

1/2/14 - Happy New Year!

While watching Swim Lessons today I learned something new and useful. Now that it's 2014 you may have noticed that the year-to-date totals on your TOS Account Statement have reset. Here's an easy way to look back at 2013.

TOS Tip: IV Rank plot/labels with SD expected moves

12/20/13

TastyTrade Game Changers has done it again. I've been wanting to plot IV Rank but it seemed way too difficult. It turns out that the plot for IV Rank looks just like the plot for ImpVolatility; only the scale is different. Duh! (Actually, want I really want is a weighted plot. Maybe later.) They threw some threshold lines on it, slapped on some labels, and even sprinkled on a few SD move labels to spice it up. Of course, I had to hot rod it a bit.

TOS Tip: Adjusting Cost Basis in TOS Risk Profile

11/24/13

When analyzing a position with Thinkorswim's Risk Profile it isn't accurate if you modified the original trade by rolling, closing half an iron condor, etc. For example, below is the risk profile for a current position in JCP.

• BTO +10 Jan14 11 C
• STO -10 Dec13 8 P

It shows I am currently up $170, with a max profit of $190 at Jan expiration if JCP stays between 8 and 11. This is confirmed by checking the closing order, which would be a debit of $20. However, TOS is ignoring my original trade and that I rolled the short puts.
