I can do it in principle, the hardest thing for me is to write the price to a file and calculate the time

Why write it to a file, you can do it like this?


It's not hard either, the moment you start counting

int iStart  = 0;
int iSeconds=20;
//---
   if(наступило событие)
      iStart=TimeCurrent(); // запомнили время в секундах
//---
   if((iStart+iSeconds)<=TimeCurrent()) // если время пришло
     {
      выполняем действие
     }

We will deal with issues as they arise...

First you have to make a table and define what should be there and where, and then write functions

int ticket;
double pricefix;
// if an object was clicked
   if(id==CHARTEVENT_OBJECT_CLICK)
     {
      // if buy button was pressed
      if(sparam=="BuyButton")
        {
         //price fixing
         pricefix = Ask; 
        
        }
     }  
    if(Ask < pricefix - 4*_Point)
    { 
   ticket = OrderSend(_Symbol,OP_BUY,0.01,Ask,3,0,Ask+300*_Point,NULL,0,0,Green);  
    }  
}

I tried to fix the price by pressing the button through a variable, hoping that when the price reaches this variable, the order will be opened, but no miracle happened. Help.

Although the function is theoretically correct, if I put

if(Ask == pricefix)
then the order opens immediately, but I need it to be 4 points lower after remembering

Hi!

I have a question.

Is there any way to remember the maximum drawdown?

I.e. today's drawdown is 16% and 20 days ago it was 5%, so the maximum drawdown is 16% and if tomorrow it is 24% then the maximum drawdown is 24%.

Or it is difficult to remember.

Or it is complicated.

CodeBase has indicators that display the Balance, Equty history from the trading history. There is more than one such tool.

Take the data and calculate it like a normal indicator

Well of course you can output to an indicator and do comparisons.

Thank you!!!

Right, there is no check for open orders.

Right, no check for open orders.

No button release function :)

Right, no check for open orders.

I'll try to add it and report back.
