Correct.
Yes, floating pip-values move inversely to price — going up when price declines, and vice versa.
I had a conversation with another poster several years ago, about pip-values for USD/JPY in a USD-denominated account. Here’s the reply I posted at that time —

You can use the information in that reply to find the answer to your question.
But, I’ll do it for you (this time).
Today the USD/JPY closed at 120.40 (ask). Using the info referenced above, we calculate the pip-value:
$1,000 ÷ 120.40 = $8.31/pip per standard lot (100,000 units of USD/JPY, worth $100,000)
If the price of USD/JPY declines to 99.00, then the same formula gives us:
$1,000 ÷ 99.00 = $10.10/pip per standard lot
You can figure the corresponding pip-values for different notional amounts (mini-lot, micro-lot, etc.).
Also, keep in mind that your broker probably rounds off the actual calculated pip-values, especially for smaller notional amounts. So for example, at the present time (based on today’s closing price for USD/JPY), it’s common for a broker to quote the following pip-values:
$8.31/pip per standard lot, $0.83/pip per mini-lot, $0.08/pip per micro-lot, etc.
This rounding-off means that price can fluctuate somewhat [I]without affecting the quoted pip-value[/I] on very small lot sizes.
Note:
Pip-value calculations for yen-pairs are unique.
Because the yen is such a tiny currency unit (approximately 1/100 the size of other [I]major[/I] currency units), the pip-value formula [I]for yen-pairs[/I] is scaled up by a factor of 100.
The pip-value formulas [I]for non-yen-pairs of the form USD/XXX in a USD-denominated account[/I] are –
$10 ÷ ask price of USD/XXX = pip-value per standard lot
$1 ÷ ask price of USD/XXX = pip-value per mini-lot
etc.
Try these formulas on USD/CHF, USD/CAD, etc., and see what results you get.
