Operating from Vietnam: clocks, sleep, payments

Monday 2 November 2026. All summer your alarm rang five minutes before the 09:30 ET (20:30 ICT, summer) open, at 20:25 in Hanoi. Tonight it rings at 20:25 ICT and the open does not come. On Sunday 1 November New York moved its clocks back one hour; Vietnam did not. The 09:30 ET open is now at 21:30 ICT (winter), and 08:30 ET (20:30 ICT, winter) is where morning releases land. Your clock changed, not the market. This lesson settles three questions before any setup: when does the US session fall in your night, how do you protect your sleep, and what must you check before money crosses borders?

Key terms

ET (giờ miền Đông Mỹ, giờ New York): the time zone of New York Definition. It is UTC−4 in US daylight time and UTC−5 in US standard time. Every time on this site is written in ET first.

ICT (giờ Đông Dương, giờ Việt Nam): Vietnam time, UTC+7 all year Definition. Vietnam has no daylight saving time.

US daylight saving time (giờ mùa hè của Mỹ, DST): the months when US clocks run one hour ahead Definition. It starts on the second Sunday of March and ends on the first Sunday of November: in 2026 from 8 March to 1 November; in 2027 from 14 March to 7 November.

Terms you need, taught later: RTH (regular trading hours) here means the US cash-equity session, 09:30–16:00 ET. Globex is CME’s electronic market, where NQ and ES trade almost 23 hours a day; the hours outside RTH are called ETH. The trading day is named after the date of its 17:00 ET close, so the session that opens Sunday 18:00 ET is Monday’s. MKT1.04 covers halts, holidays and early closes.

Chart first: the futures day on two clocks

How it works

One rule, two numbers

Vietnam time is New York time plus 11 hours in US daylight time, and plus 12 hours in US standard time Definition. The hard part is knowing which half of the year you are in, so memorise ET times, never Vietnam times, and convert.

A real date: the Fed’s decision on Wednesday 28 October 2026 came at 14:00 ET. US daylight time was still on, so in Hanoi it was 01:00 on Thursday 29 October. Four days later the same 14:00 ET slot moved to 02:00 ICT.

The US week ends at 17:00 ET on Friday (Saturday morning in Vietnam) and starts at 18:00 ET on Sunday (Monday morning). London changes its clocks on other Sundays; MKT1.04 has those dates.

Where the activity is, and where your night is

Most of a US index future’s daily movement and volume comes in the cash session, heaviest after the open and before the close, with bursts at the release times PlausibleOther market. From Vietnam that is your evening and night. The Asian hours of Globex fall in your working day but are thinner; MKT2.08 compares them. So the real question is which part of the US session you can trade while rested, every week, for years.

Common mistake: treating the busy hours as the profitable hours. The open has more volume and bigger moves; that is a base rate, not an edge. A larger move pays a trader with an edge faster and costs a trader without one faster (EV2.01).

Sleep is a trading input

Three usual windows: Evening block (house default): 08:30 ET releases and the first 90 minutes of the session, about 20:30–23:00 ICT in winter (19:30–22:00 in summer), then sleep. Late block: the last two hours, about 02:00–04:00 ICT in winter, after sleeping first. Split nights: some of each, which costs the most sleep.

House rule House rule: pick one window per night, write it in your plan, and be flat (no open position) before you sleep. A Fed decision at 14:00 ET (02:00 ICT, winter) is not your trade unless the late block is tonight’s window (M7.12).

What the data says

Worked example: a position left on while you sleep

Illustrative prices, not a real day. At 10:55 ET (22:55 ICT, winter) you are long 1 MNQ ($0.50 per 0.25-point tick, $2 per point) at 21,000.00 with a stop-market order at 20,990.00. Planned risk: 10 points = 40 ticks = $20. You go to bed.

A stop-market order becomes a market order when touched and fills at the next available price. Suppose a Fed decision at 14:00 ET (02:00 ICT, winter) moves NQ 40 points in seconds and your stop fills at 20,970.00. Loss: 30 points = $60, three times the plan, found at breakfast (MKT2.06).

The mirror. Short 1 MNQ at 21,000.00, stop at 21,010.00, and the same burst goes up: a fill at 21,030.00 costs the same $60.

The failure case. An alarm set in Vietnam time in summer is an hour early all winter, and one set in winter is an hour late all summer: arrive at 21:30 ICT in July and you have missed the 09:30 ET (20:30 ICT, summer) open by an hour.

Payments and paperwork: read, date, keep

Before you pay for an evaluation, read the firm’s help center and write down each answer with the date you read it:

1. Country eligibility. Can a Vietnam resident buy an evaluation and be paid? We have not yet verified Topstep’s answer for Vietnam (search date 2026-11-09); read the help center yourself.
2. Identity verification (xác minh danh tính, KYC): which documents, at which step.
3. Payout methods and fees. When our lab read Topstep’s payout article on 2026-11-08 it listed a bank wire, ACH (a domestic US bank network), Wise, Aeropay and a brokerage transfer. Check which methods reach a bank account in Vietnam and put the fees on your EV2.02 statement.
4. Currency. Payouts are in US dollars; your bank’s conversion to VND is another EV2.02 cost.
5. Tax forms. As general information (irs.gov), a US payer may ask a non-US person for IRS Form W-8BEN to certify foreign status; check with your firm and a qualified adviser.

Whether trading futures or prop evaluations from Vietnam is allowed for you, and how it is taxed, depends on your situation: see a qualified adviser. PROP1.02 covers the dated rule cards once verified.

Remote desks, VPNs and VPS

A common idea is to trade through a VPN or a rented US server (a VPS, virtual private server) “for lower latency”. Firms publish conduct and device rules in their help center that you must read before buying; we have not yet recorded Topstep’s current wording on VPN or VPS use, so we do not state it here. House rule House rule: trade a prop account from your own computer on your own connection, no VPN or VPS, and read the firm’s prohibited-conduct article before you buy (PROP1.04).

Do it on the platform

Windows can show a second clock for New York (Settings › Time & language › Date & time › Additional clocks). Vexity option data is frozen outside 09:30–16:15 ET, so at 07:00 ICT you read last night’s snapshot (PLAT1.02).

Drill: your week on two clocks

1. Convert 08:30, 09:30, 10:00, 14:00 and 16:00 ET to ICT for this week (US standard time until 14 March 2027) and for a week in July.
2. Choose your trading window and bedtime for each, and note the next US clock change.

Recap

• ICT = ET + 12 in US standard time and ET + 11 in US daylight time; memorise ET and convert.
• The US cash session falls in your night: 21:30–04:00 ICT in winter, 20:30–03:00 in summer.
• Pick one rested trading window per night and be flat before you sleep (house rule).
• Read and date each firm-published fact (eligibility, identity checks, payout methods, fees) before you pay; tax and legal questions go to a qualified adviser.
