Tom... Noticed in your Daily Market Commentary, & often for other past days it seems, that for the EFA/I-fund you mention the open gaps -- as having seemingly equal magnetism or drawing equal weight for being Filled by the market as C & S funds. That doesn't seem congruent with the following: (1) TSP I-fund and the EFA are (I think) impacted more than C & S funds by fluctuations of the relative values of currencies, thus gaps much more common & not as important as other non-international stocks/exchanges; & (2) I didn't go back to check, yet I vaguely recall in years-past commentaries that you mentioned/explained what I discuss in "(1)" here.
... So, what do you think about this, about gaps for the I-fund in contrast with those of C & S?
