Y/M/D and a Digit: Composing Chart Ranges from a Unit and a Number

Wed, 23 Sep 2026 00:00:00 +0000

The stock chart on Phosphor’s finance door had five time windows, chosen by five keys: 1D, 3M, 6M, 1Y, and 0 for “all history.” That’s the standard menu — every finance app has it. And like the standard menu, it had a wall you hit the first time you actually used it: you can’t ask for 3Y. Or 2M. Or 10D. Every range anyone might want is either pre-built or impossible.
