just enter your Indicator correctly

Thank you very much! I will look into it)

Greetings Professionals and Beginners, need help.

How to insert an alert in this indicator that would signal when a given upper and lower level is crossed/touched?

Tried it myself, but it doesn't work((

So, give me an example, how did you try it and where did you put the alert. It will be interesting for all to see and maybe give you the right solution.

Yes, I deleted everything at once.

didn't work, 8 errors in debugging)

I guess it's not my thing((.

probably not my thing((.

Thanks! I think I've got it sorted out, the alert when the zero level is crossed and the arrows in the direction of the crossing. but how do I make it signal at other levels?

Thanks! I think I got it, the alert when the zero level is crossed and the arrows point in the direction of crossing.

in your code - here is where to pick up the numbers

         if(Vertex_Buffer[i] > 9.9999)
            UpHisto_Buffer[i] = Vertex_Buffer[i];
         else
            UpHisto_Buffer[i] = EMPTY_VALUE;
         if(Vertex_Buffer[i] < -9.9999)
            DnHisto_Buffer[i] = Vertex_Buffer[i];
         else
            DnHisto_Buffer[i] = EMPTY_VALUE;

in the signal indicator - which has an alert . here to have more signals - remove a couple of lines

      if(CUSTOM[bar]<CUSTOMS[bar])
        {
         //if(OldTrend<0)   
            BuyBuffer[bar]=low[bar];
         //if(bar!=0)   
           // OldTrend=+1;   
        }
      if(CUSTOM[bar]>CUSTOMS[bar])
        {
         //if(OldTrend>0)   
            SellBuffer[bar]=high[bar];
         //if(bar!=0)   
            //OldTrend=-1;   
        }
     }

hello!

Decided to make owls a bit more complicated.

I want to do something like trailing, but with a single / double action

idea:

price passed 75% to take - stop decreased (for example) by 20 pips and take increased by 20 pips.

price passed 90% to take - stop decreased (for example) by 30p and take increased by 10p.

I see the scheme like this (.....function...)=> (TP - Mparametr)

where: TP - TakeProfit

Mparametr- set in external EA variables (e.g. number of points)

What functions should be used to solve this problem?

I've read about predefined variables bid,ask - should we use them as a base?

or should we use MarketInfo or SymbolInfoTick?

I have a similar solution, but its shift of stop and take depends on lots:

  if((iOTy == OP_BUY)&& (LOT()>LotControl))
             {
              dSL = NormalizeDouble(dOOP - StopLoss * Point+DownLoss * Point, Digits);
              dTP = NormalizeDouble(dOOP + TakeProfit * Point+DownProfit * Point, Digits);

              bool bOM = OrderModify(iOTi, dOOP, dSL, dTP, 0, clrNONE);
             }

I want to do something similar. relatively simple.

Or like this

I've been writing this board for almost a week and here's the problem: if I also set the pending leveller to close on the button by analogy with the approach, which was a point below when the price was reached, then for some reason it closes automatically without asking, without pressing the button, which should do it a point above (after pressing and after reaching a level as in theory you should)
