Yes. That calculating and plotting program was written in J in 2012 and had a major overhaul in 2020. The most recent improvements were using daily data instead of weekly data, adding fractional years (to display any 12-month period), and improving fractional cycles. There's actually a second program that preprocesses the daily data. It adds weekends and holidays to the data file, interpolates all "missing" OHLC price data, and averages the HLC to arrive at a single price for every day of a 365-day year--all this for ease in charting. (I suppose some day, if I feel like it, I may try to plot hi-lo bars, but I'm not sure they would add much, if anything, to the price plot because I think they would be virtually unnoticeable, at least for major stock averages.) I should note that there was one very small price I had to pay for that 365-day convenience--February 29 is always omitted. Thank you for your compliment!
