I have found a different solution.

I want to upload it, but the wheel keeps spinning and spinning...

So here are the indicator and the mqh file.

As the problem seems to be that at OnIni() CopyTime does not provide the values I need - sometimes - I do the time set in OnCalcutalte() (or OnTick()) ...

Feel free to check it and let me know what you think.

It seems to be working on Saturday, Sunday and Monday as well now, even on my side so that's perfect.

I still have an incomprehension, that could be on my side, but if you can enlighten me after reading your guides multiple times without understanding, that would be awesome.

As said, I'm using FTMO, and they switched their DST on NY date (10 March) this year, but when the bot check for DST, instead of moving from +2 to +3 like it would normally do, it did move the GMT from +2 to +4, I'm still really not sure of why it does that. It's not really impactful for now as we're in April/May, but I'd like to understand what happens there.

Taking into consideration that when comes the European DST, it comes back to a more normal number, which is DST +3 (so going from +2 to +3, which is a normal DST switch),
I hope it was understandable. It's quite messy in my head right now, so I tried to make it clear

And as said in my first message, which was telling that I think it's a bug in the code, when I compared a trading hour with trading view putting my trading view time zone to UTC+0, it was off of 1 hour, so I guess that's a coding problem as well. It occurs from 11th of March to 30th of March I think, around that. For the whole NYSumEUWin

    It seems to be working on Saturday, Sunday and Monday as well now, even on my side so that's perfect.

    I still have an incomprehension, that could be on my side, but if you can enlighten me after reading your guides multiple times without understanding, that would be awesome.

    As said, I'm using FTMO, and they switched their DST on NY date (10 March) this year, but when the bot check for DST, instead of moving from +2 to +3 like it would normally do, it did move the GMT from +2 to +4, I'm still really not sure of why it does that. It's not really impactful for now as we're in April/May, but I'd like to understand what happens there.

    Taking into consideration that when comes the European DST, it comes back to a more normal number, which is DST +3 (so going from +2 to +3, which is a normal DST switch),
    I hope it was understandable. It's quite messy in my head right now, so I tried to make it clear

    And as said in my first message, which was telling that I think it's a bug in the code, when I compared a trading hour with trading view putting my trading view time zone to UTC+0, it was off of 1 hour, so I guess that's a coding problem as well. It occurs from 11th of March to 30th of March I think, around that. For the whole NYSumEUWin

    Try this lib on yoor broker to check if it is a broker problem. https://www.mql5.com/en/code/48291

    Indeed it looks like that's a broker problem, I'm not sure of where I could check to try solving that issue, that's not going to interfere a lot with my bot, but that's still quite a problem, thanks for the help on that!

    I really don't think it's the right way of going with it, but I've made a little change to the library to adapt the offset for when the broker decides to switch with NY DST when they use London times, from my understanding, it happens only in March so I did not try to do anything for October (the other dst switch I think).

    bool setBokerOffset(bool winToSumDSTBreak = false, const bool fromInit = true)
    {
    // Bunch of your code right there
                if(DST_USD!=0 && DST_EUR==0)                          // US:summer EU:winter
                   {
                    if(winToSumDSTBreak) {OffsetBroker.actOffset = OffsetBroker.USsumEUsum = hDiff*3600 + 3600;}
                    else {OffsetBroker.actOffset = OffsetBroker.USsumEUwin = hDiff*3600;}
                    OffsetBroker.actSecFX  = sClFX; // lat second of FX-week == Close at: tCl=SoW(TimeCurrent()) + OffsetBroker.actSecFX), time left: tCl - TimeCurrent()= SoW(tB);
                    OffsetBroker.set       = true;
                   }
    // #ifdef part for debug right after (so you can see more easily) It's around line 340 to 350 of your library.
    }

    By doing that, when I put the library on my expert advisor, and I know that the broker has that issue we've spoken about, I can just add this in the inputs of my EA : 

    input bool brokerWinToSumProblem = false;       // If your broker has a DST problem in March

    And then in the init function I just need to change "isTimeSet" :

    bool isTimeSet = setBokerOffset( brokerWinToSumProblem  );


    Tell me what you think about it, it's really barbarian way of doing it, but it seems to be working so I won't complain :)

    I'll program tomorrow a solution for such sluggard broker.

    Hi @Carl Schreiber

    There used to be methods to find First Bar and Last Bar of the day, do they still exist somewhere in your lib(s)? If true please share the link.

    I remembered one of your post stating that they no longer works with updated Mql5 version, but not sure about it.
