Can you help me convert London and Newyork Markets' times to Broker's server time

[MEHMET FATIH BARUT]

Hi all,

I want to trade while London and Newyork Markets are open.

I want to use Strategy Tester in these times too.

However I only know their open and close time GMT.

Can you help me to solve this question

"When I look at the Chart I saw times, are these Broker's server time or local time?"

Chart times are broker times.

• FX opens 5pm Eastern Time (NY) Sunday and ends 5pm NY Friday. Some brokers start after (6pm is common/end before (up to 15 minutes) due to low volatility.

  Swap is computed 5pm ET. No swap if no open orders at that time.

• Brokers use a variety of time zones. Their local time (with or without DST,) GMT, UTC, GMT+2, UTC+2, NY+7.

  Only with NY+7 does the broker's 00:00 equals 5pm ET and the start of a daily bar (and H4) is the start of a new FX day.

  GMT/BST brokers, means there is a 1 or 2 hour D1/H4 bar on Sunday (depending on NY DST,) and a short Friday bar.

  GMT+2 is close but doesn't adjust for NY DST.

  EET is closer except when their DST doesn't match NY's. Last Sunday of March and 1:00 on the last Sunday of October vs second Sunday in March and return at 2:00 a.m. EDT to 1:00 a.m. EST on the first Sunday in November.

• Non-NY+7, means the chart daily bar overlaps the start, and converting broker time to NY time requires broker to GMT to NY timezone conversions.

• If you search the web you will find differing answers. Those are all wrong (half the year) because they do not take DST into account (or that it changed for the US in 2007 [important when testing history.])

• Then there are H4 candles that start on odd hours.

Do you have NY, London, and your broker's TZ and DST information, (including historical changes?) Only then, with code can you convert session times to UTC to broker's time. You can use offset inputs but then you must maintain them correctly, through all three DST changes when they occur.
