Is Borsa Istanbul Open Today?
On a full trading day, standard shares use 9:40–9:55 AM opening order collection, opening-price determination after 9:55, continuous trading from 10:00 AM–6:00 PM, then an official closing process through 6:10 PM.

Primary official sources: Borsa İstanbul's current Equity Market Trading Hours page defines the instrument groups and ETF opening exception. Its current Closing Session page gives the 18:01–18:05 order collection, 18:05–18:07 price-determination phase and 18:08–18:10 closing-price trading.

Borsa Istanbul half-day hours are more precise than “until 1:00 PM”
The official holiday calendar marks half days as Until 13:00. The detailed Equity Market schedule is more precise for cash shares: 09:40–09:55 opening order collection → 10:00–12:30 continuous trading → 12:30–12:37 closing process → 12:38–12:40 final trades at the closing price.
The Today/Tomorrow engine uses this exact cash-market schedule on Mar. 19, May 26 and Oct. 28, 2026.
What happens after 12:30 PM?
Closing margin broadcast is 12:30–12:31, order collection 12:31–12:35, closing-price determination follows, margin broadcast is 12:37–12:38, and final trades at the closing price run 12:38–12:40.
This distinction is why the page can say “cash-equity trading ended at 12:40” while still accurately reflecting the exchange-wide holiday label “until 13:00.”
Are BIST 100 trading hours the same as Borsa Istanbul hours?
BIST 100 is an index, not a separate cash exchange. Its constituent shares trade in Borsa İstanbul's Equity Market. For cash-share intent, the relevant full-day answer is the 09:40 opening process, 10:00–18:00 continuous session and closing lifecycle through 18:10.
BIST index futures can trade into the evening
Current Borsa İstanbul VİOP index futures trade 09:20–18:10 in the normal session and 19:00–23:00 in the evening session. That does not create an evening cash-equity session for BIST 100 constituent shares.

A scheduled clock does not override a live BIST circuit breaker
Borsa İstanbul operates instrument-level and market-wide circuit breakers. Its current Market Functioning page states that if the market-wide trigger occurs within the final 30 minutes of continuous trading, the Equity Market can remain halted and restart directly with the 18:00 closing session.
Does Borsa Istanbul close for lunch?
No. Standard continuously traded equities have no scheduled midday lunch break. Full-day continuous trading is 10:00–18:00; half-day continuous trading is 10:00–12:30.
Does Borsa Istanbul change clocks?
Turkey currently uses UTC+3 year-round. CalendarHours still uses `Europe/Istanbul` instead of a manually fixed offset.
Why can BIST-related futures trade after cash shares stop?
Because VİOP is a separate derivatives market. Current index-futures documentation lists a 09:20–18:10 normal session and a 19:00–23:00 evening session.

Borsa Istanbul Hours FAQ
Is Borsa Istanbul open today?
For standard continuously traded cash equities on a full trading day, Borsa İstanbul uses opening order collection from 9:40 AM to 9:55 AM Istanbul time, opening-price determination after 9:55 AM, continuous trading from 10:00 AM to 6:00 PM, and an official closing session from 6:00 PM through final trades at the closing price ending at 6:10 PM. CalendarHours also checks the official 2026 full closures and half trading days.
What time does Borsa Istanbul open?
The Equity Market opening call begins at 9:40 AM Istanbul time. Standard-share order collection runs to 9:55 AM, opening-price determination follows, and continuous trading begins at 10:00 AM. ETFs have a slightly later opening call through 9:56 AM.
What time does Borsa Istanbul close?
Continuous equity trading ends at 6:00 PM. Borsa İstanbul then runs the closing session: margin broadcast 6:00–6:01 PM, closing order collection 6:01–6:05 PM, closing-price determination through about 6:07 PM, another margin broadcast 6:07–6:08 PM, and trades at the closing price from 6:08–6:10 PM.
Why do some websites say Borsa Istanbul closes at 6:00 PM while others say 6:10 PM?
6:00 PM is the end of continuous trading. The official closing session continues through 6:10 PM, so both numbers can appear depending on whether a source means continuous trading or the complete cash-equity trading lifecycle.
What are Borsa Istanbul pre-market hours?
The relevant cash-equity opening phase begins at 9:40 AM. Standard shares collect opening orders through 9:55 AM, then opening-price determination occurs before continuous trading begins at 10:00 AM. This is an opening auction, not a U.S.-style multi-hour electronic premarket.
What time is the Borsa Istanbul closing auction?
The closing lifecycle starts at 6:00 PM with margin broadcast. Closing-auction order collection runs from 6:01 PM to 6:05 PM, followed by closing-price determination through about 6:07 PM. Final trades at the closing price run from 6:08 PM to 6:10 PM.
Does Borsa Istanbul have after-hours trading?
Not in the U.S.-style sense for cash equities. The 6:00–6:10 PM closing session is part of the official exchange session. VİOP derivatives are different: current index futures can have an evening session from 7:00 PM to 11:00 PM.
What are BIST 100 trading hours?
BIST 100 is an index, not a separate stock exchange. Its constituent shares trade on Borsa İstanbul. On a normal full day, the main continuous share session is 10:00 AM–6:00 PM, surrounded by the opening process beginning at 9:40 AM and the closing session through 6:10 PM.
Are BIST 100 futures hours the same as stock-market hours?
No. Current Borsa İstanbul VİOP index futures trade continuously from 9:20 AM to 6:10 PM in the normal session and from 7:00 PM to 11:00 PM in the evening session. That derivatives schedule is separate from cash shares.
Does Borsa Istanbul close for lunch?
No. On a full trading day, standard continuously traded equities run continuously from 10:00 AM to 6:00 PM without a scheduled lunch break.
What are Borsa Istanbul ETF hours?
Borsa İstanbul states that the ETF opening call runs from 9:40 AM to 9:56 AM, one minute later than the standard-share opening order-collection endpoint. ETF continuous trading starts at 10:00 AM and ETFs are handled as a distinct instrument type inside the Equity Market.
What are Borsa Istanbul half-day hours?
On an official half trading day, the cash Equity Market runs from the 9:40 AM opening process through final closing-price trades ending at 12:40 PM. Standard-share continuous trading runs 10:00 AM–12:30 PM, followed by closing phases from 12:30 PM to 12:40 PM.
Which Borsa Istanbul dates are half days in 2026?
The official 2026 calendar marks March 19 for Ramadan Feast, May 26 for Eid al-Adha, and October 28 for Republic Day as half days. The holiday table says the exchange is open until 1:00 PM, while the detailed Equity Market cash schedule ends final closing-price trades at 12:40 PM.
What are Borsa Istanbul holidays in 2026?
The official 2026 calendar lists January 1, March 20, April 23, May 1, May 19, May 27–29, July 15 and October 29 as weekday full closures. March 21–22, May 30 and August 30 fall on weekends. March 19, May 26 and October 28 are half days.
Is Borsa Istanbul open on October 28, 2026?
Yes, but only for a half day. October 28 is marked by Borsa İstanbul as open until 1:00 PM. The detailed Equity Market cash schedule finishes continuous trading at 12:30 PM and closing-price trades at 12:40 PM. October 29 is fully closed.
What time zone does Borsa Istanbul use?
CalendarHours uses Europe/Istanbul. Turkey currently remains on UTC+3 year-round, so Borsa İstanbul does not make the seasonal CET/CEST-style clock changes seen at many European exchanges.
What is the difference between Borsa Istanbul Equity Market and VIOP?
The Equity Market is the cash venue for shares, ETFs and related instruments. VİOP is the derivatives market for futures and options. Their clocks differ: cash shares use the 9:40 AM opening process and 10:00 AM–6:00 PM continuous session, while many VİOP contracts use a 9:20 AM–6:10 PM normal session and selected contracts also have a 7:00 PM–11:00 PM evening session.

Accuracy & Methodology
How CalendarHours verifies Borsa Istanbul hours
CalendarHours prioritizes Borsa İstanbul's current Equity Market Trading Hours page, Closing Session and Market Functioning pages, the official 2026 holiday calendar, detailed BISTECH Equity Market schedules and current VİOP product pages. Live status uses `Europe/Istanbul`.
The normal cash-equity lifecycle is modeled as 09:40–09:55 opening order collection, opening-price determination after 09:55, 10:00–18:00 continuous trading, 18:00–18:01 closing margin broadcast, 18:01–18:05 closing order collection, closing-price determination through about 18:07, 18:07–18:08 margin broadcast and 18:08–18:10 closing-price trading.
The official 2026 holiday calendar is combined with the detailed half-day Equity Market schedule. Mar. 19, May 26 and Oct. 28 use 10:00–12:30 continuous trading and final closing-price trades ending at 12:40.
Product-specific differences are kept separate: ETFs have an opening call through 09:56; warrants, certificates and rights do not participate identically in every closing phase; single-price instruments have auction-based schedules; and VİOP futures/options use a different derivatives clock.
