So, then you have to plan ahead for two days instead of one?
By this logic, and I'm just making sure I understand this correctly:
On Friday 1/26 I did an IFT before noon. I had 50 G, 25 S, 25 I. Share prices for G 11.75, S 19.04 and I 22.24 as of COB 1/26.
Monday, 1/29 G was 11.76, S 19.13, I 22.32. So, I got the gain for the COB Monday by doing the IFT on Friday. Our balance reflects that.
On Tuesday 1/30 I did an IFT 100% G. Since S and I went up again to 19.35 and 22.51 respectively, I sold at the gain for COB 1/31 even though the IFT was noon on 1/30. Since G was static until I made the IFT on Friday, my balance is the same as it was for the IFT I made by noon on 1/30.
Now, I have to hope that S and I go up on Monday since I bought higher than I thought I was. Do I have that right or am I just out of my mind with confusion?
On the plus side, I thought I lost out on the S and I gain by moving to G, but because of the day delay, I got the higher selling price.
My dh just started contributing to the TSP last March, so our balance is small, but I want to figure this out since we are early in the game before dh retires 18 years from now.
