Friends, help a dummy. The idea is as follows: When the "Ind" variable reaches the set level, switch to waiting for "Value" to change direction while waiting for "Ind" to no longer reconcile.

   if(Ind[0]<=-0.7)
     {
      while(Value[3]>Value[2]<Value[1])
        {
         if(CopyBuffer(InpInd2_Handle,1,SignalBar,3,Value)<=0)
           {
            Recount=true;
            return;
           }
        }
      if(BuyPosOpen) BUY_Open=true;
     }

What is the right way to do this?

   if(Ind[0]<=-0.7)
     {

replace by

   bool pravda=false;

   if(pravda || Ind[0]<=-0.7)
     {
      pravda=true;

Friends, help a dummy. The idea is as follows: When the "Ind" variable reaches the set level, we switch to waiting for "Value" to change direction, without checking "Ind" again while waiting.

What is the correct way to do it???

I think there is a mistake here :

while(Value[3]>Value[2]<Value[1])

It has to be:

while(Value[3]>Value[2] §§ Value[2]<Value[1])

Where on the keyboard is the paragraph symbol? I thought it had been disabled...

while(Value[3]>Value[2] §§  Value[2]<Value[1])

It should be:

This is not generally the case, you can get by with

while(Value[2]<Value[1])

If I did it correctly (which is doubtful), it hangs, apparently it won't come out of the loop.

 bool pravda=false;

   if(pravda || Ind[0]<=-0.7)
   pravda=true;
   
   {   
      
      while(Value[2]<Value[1])
         {
         if(CopyBuffer(InpInd2_Handle,1,SignalBar,3,Value)<=0) {Recount=true; return;}

         if(SellPosClose) SELL_Close=true;
         UpSignalTime=datetime(SeriesInfoInteger(Symbol(),InpInd_Timeframe,SERIES_LASTBAR_DATE))+TimeShiftSec;
         }

Tried it, same thing. When Ind goes over the level, it hangs.

Tried it, same thing. When Ind exceeds level, it hangs.

1. Make bool pravda global.(https://www.mql5.com/ru/docs/basis/variables/global)

2. Replace while with if.

3. When if (from step 2) works, return pravda=false.

Friends, help a dummy. The idea is as follows: When the "Ind" variable reaches a given level, we switch to waiting for "Value" to change direction while waiting for "Ind" not to be checked again.

Are you sure that the indicator is recalculated during the while loop?
