688307 on Shanghai
In data feeds: 688307.SS. The quote screen more often shows 688307. Exchange: Shanghai. Market: China A-shares.
The rule does not change because 中润光学 is famous or obscure.
NineRadar lists who finished after the close on the hot list and the watchlist. If 688307 is absent, the stretch may be unfinished, or it was not in the last scan.
After the close
中润光学 only takes the China A-shares cash close. Do not mix HK, US, CN, and KR on one “today” line.
A low-9 is not a buy. A high-9 is not a sell. A one-way tape can print several 9s and never turn.
The same rule as every other name
On 中润光学, a daily 9 is nine closes versus the close four bars back. Below prints a low-9. Above prints a high-9. Fail bar 9 and 1–8 vanish.
Labels usually start at 6. A 13 waits for a finished 9; bar 13 must pass bar 8’s close or it plots +.
China A-shares cash close is 15:00 China time. Lunch, after-hours, and a 120-minute print are other clocks.

Answers for this name: scan date, 15:00 China time, low-9 / high-9, 13, alerts. A count, not an order.
Has 688307 completed a daily magic nine?
The last scan did not include 中润光学. That does not mean the software is broken, and it does not mean 688307 has no structure. Add 688307 on the watchlist in Nine Radar and count the 15:00 China time cash close.
Is a low-9 on 中润光学 a bottom-picking signal?
Do not treat a low-9 on 中润光学 as a buy, or a high-9 as a sell. A low-9 is nine daily closes below the close four bars back. A high-9 is nine closes above that bar. 中润光学 can print several 9s in a one-way tape and never turn.
Why is the 9 on 中润光学 different in my charting app?
It should match: nine closes versus four bars back; fail the ninth and the stretch clears. In data feeds this is 688307.SS; the quote screen more often shows 688307. If two terminals disagree, check timeframe (daily vs daily), adjustment mode, and whether an intraday print was treated as the close. NineRadar’s extra job is the after-close list, not another line on the chart.
Which close does 中润光学 use for a daily 9?
中润光学 is China A-shares (Shanghai). The daily 9 waits for the 15:00 China time cash close. Lunch, an unfinished auction, and the after-close print are not today’s daily 9. A 60- or 120-minute 9 is another clock. Do not paste it into the same “today’s daily 9” line.
Why is there no 13 after a 9 on 中润光学?
Not a bug. A finished 13 is rarer than a finished 9. Most sessions on 中润光学 have no 13. Countdown starts after a daily 9; bar 13 still has to pass bar 8’s close.
Will this website notify me when 中润光学 prints a 9?
The website does not push. Install Nine Radar on iOS and add 688307 (中润光学) to the watchlist (free: eight names). Pro can push a finished 9 or 13 to the lock screen after the 15:00 China time cash close. Finished 60/120-minute 9s live in the app only.
Do the web and iOS use the same 6–9 marks on 中润光学?
Daily 6–9 marks use the same count: closes versus four bars back, labels from 6. This page is for reading 中润光学 after the close. Lock-screen alerts, 60/120-minute counts, and closed-pair replay are in the iOS app. The website does not shout a 9 during the bar.
Does 中润光学 bounce after a low-9?
NineRadar does not publish an accuracy rate for 中润光学, and it does not call a low-9 a bottom or a high-9 a top. Replay scores closed pairs only: a low-9 waits for the next high-9. 中润光学 can print several 9s in a one-way tape. History does not forecast the next bar.
