Price, intraday and daily → the candlestick chart, by the minute or the day

Since the series began

Both start at 100 on 1 Jul: each close divided by that day’s close. 92 sessions to 9 Nov. A dot is a session that moved unusually.

Nothing unusual in the 17 sessions checked since 16 Oct. A company moving normally makes one about once every 80 sessions.

How this is calculated

Price: Finnhub's live trades in US hours, one tick per second; the daily bar from one quote at 16:15 New York, with open, high, low and close but no volume.
Chart: Daily closes as stored, each divided by the close on 1 Jul and multiplied by 100, for TKC and IXP alike: the first session both have a close. It grows by a session each day.
Unusual: The move left after subtracting global telecom companies (IXP)'s, measured against the last 60 trading days (σ) and recomputed nightly. A close beyond 2.5σ is an unusual move; beyond 5σ, an extremely unusual one.
Sessions: Every session from 16 Oct has been checked. The bars begin earlier, backfilled from the same feed, but nothing before that date was tested, so the count does not reach back past it.
Country: The business country the US regulator's filings give the company: Türkiye.
Currency: Where the European Central Bank publishes the country's exchange rate, the same day's rate separates the currency's move from the stock's; where it does not, the move says why.
News: Fetched because the move was unusual, never on a timer; every outlet that names the subject is kept, split at the close.
