The issue also might come from what kind of indicator you use to generate the strategy.

I try to test it live on 1 minute chart but it still not opening orders. In tester on 1 minute period its opening orders just in 00:00 where should be opened daily but just on date when test starts. After that no more trades. Can somebody help?

May I ask which broker you are using? Possibly Pepperstone or Global Prime? The reason is this, both brokers have a trading break at 0:00, but still stream prices. So your EA will try to enter at that time (start of a new daily bar), but can´t, because it will get rejected with "market is closed". Do you see any such error in the "journal" tab?

I am avoiding this by adding my custom code to the EA´s to do a trading break from 23:59 to 0:01 server-time, so the order can be placed at 0:01 by the EA. It´s not exactly accurate like in the backtests then, but at least you get in. And believe me, you anyway do not wish to open the order at 0:00, as this is roll-over-time and spreads jump to 30 to 40 pips for that minute VERY often. So it´s better to wait for 0:01. Maybe Popov can insert such a simple function into the generic code of FSB (and EA Studio). Here is how I do it in my EAs, maybe that helps. I simply check if the "trading break" is currently active at the same place I check for a new bar (which would be needed in order to enter a trade, as my EAs only trade on bar open):

extern string TradingBreakFrom = "23:59";
extern string TradingBreakUntil = "00:01";

   static datetime timeCur;
   bool isNewBar = false;
   if (timeCur != Time[0] && checkTradingBreak(TradingBreakFrom, TradingBreakUntil) == false) {
   isNewBar = true;
   timeCur=Time[0];
   }
   
   if(isNewBar){
..............................

bool checkTradingBreak(string TimeFrom, string TimeTo)
{
    bool RevertRange = false;

    if (TimeStringToDateTime(TimeTo) < TimeStringToDateTime(TimeFrom))
        RevertRange = true;

    if (RevertRange == false && (TimeCurrent() < TimeStringToDateTime(TimeFrom) || TimeCurrent() > TimeStringToDateTime(TimeTo)))
    {
        return(false);
    }
    else if (RevertRange == true && (TimeCurrent() > TimeStringToDateTime(TimeTo) && TimeCurrent() < TimeStringToDateTime(TimeFrom)))
    {
        return(false);
    }

    return(true);
}

datetime TimeStringToDateTime(string time) {
   string date = TimeToStr(TimeCurrent(),TIME_DATE);//"yyyy.mm.dd"
   return (StrToTime(date + " " + time));
}

What this does is to simply NOT tell the EA that a new bar has opened if we are currently within the trading-break. So the "new bar event" which normally would have happened at 0:00, gets delayed until 0:01, regardless of the timeframe of the chart, it can place the order at 0:01 and does not have to wait until the next "real" bar (which would be very bad for H1 / H4 / D1 strategies). Maybe an idea for Popov.... ;-)

Please report, if you find more info or some suspicious behavior.

Anyway, this is a very common question.
It is important to understand that the strategies start trading not when you put on the chart, but when the used indicators form a suitable signal.

Especially on a D1 chart, it may take weeks before the first trade.
