Local Time Zones incl. Daylight Savings for Charts

Chart & drawings

Current situation:

Data are stored with UTC (Universal Time) time stamps and the user can define a static offset value on exchange or symbol basis in order to define how many hours time shift ATAS applies in chart (and tape) windows in order to display the data in local time (or whatever time the user chooses). Daylight saving time adjustments need to be implemented via an adjustment of the offset value which then is applied to the complete history shown in the chart.

Problem:

It is not possible to generate a chart which correctly displays historical data which consider daylight savings and contain summer times and winter times within this chart. It is necessary to decide between summer and winter time for the complete displayed time span. This leads to a partial time shift for any time-filtered indicator. e.g. Relative Volume, VWAP (with time filter), Daily Lines (with time filter), MP+TPO (with time filter) etc. In the screenshot above the US-Opening is shifted between 14:30 and 15:30 CET (Central European Time) -please see the blue vertical lines- but it applies to any exchange which does not trade in UTC time zone.

Proposal:

Instead of the static (UTC basis+offset) value for time zones ATAS should offer all the different local time zones incl. daylight savings (as available in windows) + offset value.

This would allow to combine daylight saving periods of the exchange with the regular time shift to the local time of the user, like e.g. US-Eastern time + 6 hours (US daylight savings combined with CET time zone).

    Indian Standard time must be added atleast for Binance & Bybit. It's getting a bit difficult for me eventually to recognise the time patterns & then trade!

    Also plz make the search function simpler! A bit easy like Trading view where I can select Only Perpetual Swaps on Binance Futures Exchange and not any other exchanges or other stocks or bonds when I input a special keyword.

    Searching 1M Baby Doge, 1000floki are a bit hassling but it could be made easier which could drastically ease up the loading time

    I have previously suggested this and included the objects to shift too so that if you have set up sessions they are correctly in sync when the time zone is adjusted on the chart.

    Agree. Users must be able to specify real timezones indead of time shift. Daylight saving time must be applied automatically.
